The History of Ever

[Herms]

AKA “That Is All”
Or the “Strongester Lovinger Timeline”

Basically this is a revamp of my Stronger Loving Timeline thread, with information from the DBO timeline, plus the Timeline Evaluation, The Awkward Age, and Longest Days threads combined. However, this is really in large part what was going to be the Kanzentai Timeline Guide, which would itself have been all that stuff (except for the detailed DBO timeline, which of course I only did recently). It also ended up including various other bits and pieces of other guides that never quite got down. The entries on the DBO time quests are based on information kindly provided by TheDevilsCorpse, and gohan2k broke down the anime 22nd TB timeline.

The thing about the Kanzentai Timeline Guide was that all the entries would be assigned categories (ie anime-only stuff, Saiyan history, Goku’s life, etc), and fancy HTML would allow you to toggle things on and off so that you could view a manga-only timeline, or a timeline that goes with the anime instead, or one that only features entries relating to the Red Ribbon Army, or whatever. Or if you wanted to you could just have the big giant huge timeline with everything. Lacking any HTML skills, I’m just going to be posting up that huge giant timeline with everything, which sounds neat but can be sub-optimal at times, since some of these entries weren’t intended to be read on the same timeline, and the whole thing comes out to be really long.

I have though tried to set apart entries relating to flat-out alternate versions of the same time period, by putting those in quote tags. This is done with times when the anime version is different from the manga (like with the 22nd Tenkaichi Budokai being several days rather than one day), with Trunks and Cell’s alternate timelines, with the movies (though not the Bardock or JSAT specials), with the main events of GT, and with the DBO time quests. Events leading up to those things are not put in quotes however. That is, the events of DBZ Movie 4 in Age 762 are in quotes but Slugg’s origin in Age 261 isn’t (though it is still marked as relating to DBZ Movie 4), because only the main events of the movie create timeline organization problems. I’m also not trying to say that GT counts less than DBO by putting it in quote tags; it just seemed like the easier one to set apart that way.

For the time-travel alternate timelines, I'm basically using the numbering from Daizenshuu 7's alternate timeline explanation page, where the main series timeline is Timeline I, "future" Trunks' timeline is Timeline II, and the main Cell's timeline is Timeline III. In other words, Timeline I's Cell is the one killed as a fetus by Trunks and Kuririn, Timeline II's Cell is the one Trunks kills, and Timeline III's Cell is the one who reaches his perfect form and is killed by Gohan. This is a rather silly numbering system all in all, since "Timeline I" is really the one produced by the time-travel in the other two timelines, but it seemed convenient for my purposes. Daizenshuu 7 also has a Timeline IV, but I've not included it because I don't think their explanation of it makes much.

Entries are followed by a reference box explaining what they’re based on. Most of the specific dates come from Daizenshuu 7, but I’ve tried to explain the reasoning behind those dates. I’ve also included a number of entries with estimated or even somewhat arbitrary dates, and explained what my reasoning is. These are also typically phrased as “Roughly X?”, to mark them as guesses. Besides the date, if any information in an entry is speculation, it’ll be in brackets. I figure it’s OK to take wild guesses if I tell you when I’m doing it.

Besides the basics of a timeline, there’s also a good deal of explanations and extra background info, particularly at the start. Some of this is a holdover from the idea of the Kanzentai Timeline Guide offering histories of specific elements of the series, some of it is just me trying to expand on entries that were originally just “X is born”, some of it is random tidbits I haven’t managed to incorporate into my other guides, and some of it is leftover from other aborted guides. This is going to be my final guide for the foreseeable future, so I wanted to go out with a bang.

For quick reference, he’s the year numbers for the major story arcs/series, with the total number of years since Goku met Bulma noted:

Age 749: Hunt for the Dragon Balls, start of Kame-sennin’s training
Age 750 (1 year): 21st Tenkaichi Budokai, Red Ribbon Army, Uranai Baba
Age 753 (4 years): 22nd Tenkaichi Budokai, Piccolo Daimao
Age 756 (7 years): 23rd Tenkaichi Budokai
Age 761 (12 years): Raditz
Age 762 (13 years): Vegeta and Nappa, Freeza
Age 764 (15 years): Trunks
Age 767 (18 years): Androids, Cell Games
Age 774 (25 years): High school, 25th Tenkaichi Budokai, Majin Boo
Age 784 (35 years): 28th Tenkaichi Budokai (end of manga/DBZ)
Age 789 (40 years): Start of GT, Ultimate Dragon Balls, Baby
Age 790 (41 years): Earth explodes, Tenkaichi Budokai, Super No.17, Evil Dragons
Age 890 (141 years): Goku Jr., end of GT
Age 1000 (251 years): DB Online

And here’s a few important events from before the series:
c. 5,000,000 Before Age: Majin Boo is born
Age 261 (-488 years): Disaster on Namek
Age 461 (-288 years): Piccolo Daimao’s rampage
Age 737 (-12 years): Goku’s birth, Planet Vegeta’s destruction

At this point I should perhaps explain a bit about the DB calendar. In Chapter 358, Trunks inspects Cell's time machine and says it came form "Age 788". This is the only reference to a specific year within the actual series itself. Starting with Daizenshuu 7 though, the guidebooks and other secondary material have made use of an elaborate calendar based around that single reference, as you can see above. The year marker is "Age", placed before the year number. DB is mostly set within the Age 700s, while the GT Special and the final scene of GT are around Age 890, and DB Online's main story is in Age 1000. This calendar is unrelated to the Gregorian calendar. Sometimes you see DB fansites label DB years as "A.D.", but this is simply a clumsy though widespread mistranslation. DB Online clearly and repeatedly uses the English spelling "Age", and both the Viz manga and Funi DVD subtitles use "Age" for that single reference in the Cell arc.

In fact, Daizenshuu 7 says that certain parts of DB Earth do use the Gregorian calendar, which is distinctly separate from the "Age" one. This is mostly a reference to Dr. Slump, and going off of that Age 745 (the official year of Arale's creation) seems to equal 1980 A.D. In any case, the world of DB is a fantasy one unrelated to the real world, so none of these years have any relation to our idea of the present. It should be noted though that the first chapter of DB does refer to the story as taking place "long, long ago".

To hopefully make it a little easier to jump to particular parts, I've included a Find tool navigation system like in the Strength Checker. To go to a certain part, use the Find tool on your internet browser to use the following codes, putting # before them. So to go to section ABC, search for #ABC. For story arcs:

DRA: Search for the Dragon Balls
TRA: Kame-sennin's training
21T: The 21st Tenkaichi Budokai
RRA: Red Ribbon Army
UBB: Uranai Baba
22T: The 22nd Tenkaichi Budokai
PIC: Piccolo Daimao
23T: The 23rd Tenkaichi Budokai
SAI: Saiyans
FRE: Freeza and Namek
TRU: Trunks's first appearance
CEL: Cell and the androids
BOO: High school, 25th Tenkaichi Budokai, Majin Boo

For GT:
GT1: Ultimate Dragon Balls, Baby
GT2: Earth explodes, Tenkaichi Budokai, Super No.17, Evil Dragons

For DB Online:
DBO1: the pre-Age 791 stuff on the DBO timeline.
DBO2: Age 791 onward on the DBO timeline. The earlier stuff is around the same time as the GT stuff, so I figured it'd be good to be able to skip past that if you only want to read about DBO.
DBO3: Age 1000 and afterward.

Then there are codes for specific time periods:

DAW: Dawn of Time
BA: Before Age; starts about 10,000 years ago.
AGE: The early Age years.
200: the Age 200s
400: The Age 400s
500: The Age 500s
600: The Age 600s
700: The Age 700s
710: The Age 710s
720: The Age 720s
730: The Age 730s
740: The Age 740s
750: The Age 750s
760: The Age 760s
770: The Age 770s
780: The Age 780s
790: The Age 790s
800: The Age 800s
900: The Age 900s
1000: Age 1000 and beyond

Anyway, let’s get this thing started.

[Herms]

THE DAWN OF TIME? (#DAW)
The Dragon World is created
--The cosmos consists of a giant ball, divided into two halves. The upper half is the afterlife, the realm souls naturally arrive at when they die. The lower half is the living world, itself consisting of two parts. The upper part is the universe, ruled by science, while the lower part is the Demon Realm, ruled by magic. The walls of this cosmic ball are inscribed with strange symbols, and outside is a separate, miniature cosmos that revolves around the other like a moon. Though clearly artificial and constructed, the creator of either of these two cosmos is unknown. [Some say they were made by a being known as “Akira Toriyama”, though nobody, not even Toriyama, can now remember.]
[Ref: Basically just a description of the Dragon World, taken from the cosmos map in Daizenshuu 4 plus the Daizenshuu 7 world section and glossary. Toriyama’s Daizenshuu 7 bio playfully describes him as the “ultimate ruler of the DB World” and someone “far, far more important than even the Grand Kaioshin”. The date is self-explanatory, I guess.]

Untold MILLIONS OF YEARS AGO?
The World Tree
--Somewhere within the cosmos, the planet Kaishin [World Core] comes into existence. On it grows the gigantic Kaiju [World Tree]. The Kaiju produces fruit, and from the pits of its fruit are born the Shinjin [Pit People]. The Shinjin are genderless, though some can look more like men and others more like women. Their average lifespan is 75,000 years, their population typically around 80, and they spend their days studying various subjects in a large castle that serves as a school. They are clairvoyant, have telepathic powers and the ability to materialize objects through thought. Very rarely, the Kaiju produces a golden fruit, from which a special type of Shinjin is born, far more powerful and capable of living for millions of years.

The origin of the gods
--Eventually, the Shinjin take it upon themselves to becomes gods, organizing and overseeing the cosmos. They divide the countless worlds of the universe into four areas, which they term “galaxies”, and name after the cardinal directions: the North Galaxy, South Galaxy, East Galaxy, and West Galaxy. For each galaxy, a Shinjin is chosen by lottery to become a “Kaio” [World-King] and oversee its worlds. The four Kaios live in the afterlife, and are overseen by a “Grand Kaio”, also chosen by lottery.
--Gods are also appointed for individual planets. They are not chosen from among the Shinjin, but from among strong and pure-hearted members of each planet’s sentient life. Attendants from the afterlife are dispatched to assist these gods, but can only act in subservient roles, so that a species’ fate will be entrusted to the species itself.
--To oversee the gods themselves, for each Kaio an equivalent “Kaioshin” [World-King God] is appointed. The Shinjin born from the rare golden are selected by lottery for these posts. They oversee the north, south, east, and west of not only the living world, but the afterlife and its gods as well. Above the Kaioshins of the cardinal directions is a Grand Kaioshin, who oversees the entire cosmos. The five Kaioshins live in the Kaioshin Realm, the separate cosmos that revolves around the main cosmic ball like a moon. The Kaioshins’ secret weapon is the Potara earrings, which enable any two beings to permanently combine into one and vastly power up.

The roots of evil
--However, even the divine eyes of the Kaios and Kaioshins cannot penetrate into the Demon Realm, a chaotic realm which is home to the Makaios [Demon-Realm-Kings] and Makaioshins [Demon-Realm-King Gods]. These are the antithesis of the Kaios and Kaioshins, and govern evil. Their origin is obscure, but occasionally evil Shinjin are born, which go to the Demon Realm and ally themselves with the Makaios.
[Ref: Description of Planet Kaishin, Kaiju, its fruit, the Shinjin, and the Makaio/shins are from Toriyama’s explanation in the SEG: Character Volume. For the dating I’m assuming here that Shinjin society as outlined by Toriyama predates the existence of the North Kaio’s planet. The explanation of the god system and Kaioshin Realm is from Daizenshuu 7’s world section and glossary. The description of Shinjin special powers is taken from the “People of the Cosmos” section in Daizenshuu 4’s racial guide, though this was about DB gods in general and not specifically Shinjin (which wasn’t a term that had been created yet). Toriyama says the Shinjin lifespan is about 75,000 years, but East Kaioshin is supposedly over 5 million, so I’ve tried to reconcile that. I also tried to explain Toriyama saying that the Shinjin are genderless, though North Kaio can pee standing up and the anime shows South Kaio and West Kaioshin as women. The description of golden Shinjin as more powerful than regular ones comes from comparing East Kaioshin’s power to North Kaio’s, and just assuming that’s typical. Elder Kaioshin explains about the Potara in Chapter 501.]

Over 100 MILLION YEARS AGO
North Kaios’ planet already exists
--The four Kaios live on special worlds in the afterlife, each one like a miniature version of Planet Kaishin. The North Kaio’s planet already exists at this time, accessible only via the million kilometer “Serpent Road” which sits above Hell, though the current North Kaio is not born yet. When ordinary people or those especially evil die, they lose their bodies and enter the afterlife only as souls. Certain people though are allowed to keep their bodies after death, typically in recognition of great achievements, and receive training from the Kaios.
[Ref: The date is from Daizenshuu 7. The Guide Oni in Chapter 205 says he thinks Elma Daio is the only person to have crossed the road and reached Kaio’s planet in 100 million years, so presumably the planet and road are at least that old. Toriyama in the SEG: Character Volume establishes that the average lifespan of Shinjin is 75,000 years, putting this well before the current North Kaio’s time. Also in SEG: Character Volume, Toriyama describes Planet Kaishin as a gigantic version of the planets the Kaios live on. The explanation of bodies in the afterlife is from Daizenshuu 7’s world section, and in Chapter 417 Goku says regular and really evil people like Cell don’t get bodies in the afterlife.]

--DBZ Episode 195: The Grand Kaio lives on his own planet at the highest point in the afterlife. Those allowed to keep their bodies in the afterlife can also gather on this planet in the hope of eventually receiving personal training from the Grand Kaio.
[Ref: As shown in the episode. I’m assuming Grand Kaio’s planet is at least as old as North Kaio’s.]

Circa 75 MILLION YEARS AGO
The Dragon Balls are created
--On Planet Namek, members of the Namekian Dragon Clan create “Dragon Balls”, magical artifacts which can grant any wish. Dragon Ball sets consist of seven balls, each one containing a different number of stars, and when all seven are gathered a dragon will appear and grant wishes. The East Kaioshin of the time fears the way in which the Dragon Balls confuse the natural order, and allows only the Namekians to use them, since they are the only ones he trusts to use them responsibly. He also warns the Namekians against using the Dragon Balls for the sake of other planets.
[Ref: Elder Kaioshin explains warning the Namekians in Chapter 509. This must have been before his imprisonment, so I’m using the Daizenshuu 7 dating for that. It’s possible though that this occurred millions of years prior to his imprisonment. Dragon Clan Namekians being the ones who make Dragon Balls is from Chapter 265 and 393.]

--DBGT: Whenever Dragon Balls grant a wish, their Plus Energy decreases, while their Minus Energy increases. Plus Energy is positive, righteous energy, while Minus Energy is negative and evil. To purge the negative energy created by granting wishes, a Dragon Ball set should not be used for another hundred years. Otherwise, Minus Energy will overflow, creating Evil Dragons. Because they are born from negativity, these Evil Dragons hold only negative desires such as destruction. Once when Evil Dragons appeared on a certain planet, it and countless other planets surrounding it were wiped out. [This was probably one of the East Kaioshin’s concerns when he restricted the use of Dragon Balls to Planet Namek alone.]
[Ref: From GT Episode 48, plus a bit from GT Perfect File Vol.2’s explanation of the Evil Dragons. Mister Popo says the thing where Evil Dragons appeared and wiped out lots of stuff was “long, long ago”. I’m just putting all this stuff here because it fits with Elder Kaioshin warning Namekians, but it could be any time really.]

The Elder Kaioshin is sealed
--The East Kaioshin carelessly allows an old witch to take one of his Potara earrings. Not knowing what it is, she puts it on, merging the two forever. As a result, the East Kaioshin is stuck with the witch’s aged appearance, but he also gains several mysterious abilities. Most notably, he now has the ability to draw out anyone’s hidden power to far beyond its limits.
[Ref: Elder Kaioshin mentions fusing with the witch in Chapter 502, and says this is where his abilities come from. I’m assuming this happens in the same general era as his imprisonment, and arbitrarily placing it after his warning to the Namekians. The Elder Kaioshin formally being an East Kaioshin is from DBZ Son Goku Densetsu.]

--A certain powerful, evil being [perhaps a Makaioshin?] becomes afraid of the East Kaioshin’s ability to draw people’s power out beyond its limits, and seals him within the Z Sword. The Z Sword is planted up to its hilt into a mountain in the Kaioshin Realm. Over the next 15 Kaioshin generations (equivalent to 75 million years), countless Kaioshins attempt to pull the sword out, both to free the trapped East Kaioshin inside, and to receive the tremendous power-up he grants. None succeed. Over time, the Kaioshins forget about the trapped East Kaioshin, and come to believe that the Z Sword itself grants tremendous power.
[Ref: Elder Kaioshin’s imprisonment is described in Chapter 479, but no date is specified besides it being 15 generations ago. Daizenshuu 7 dates this to 75 million years ago, perhaps because the current East Kaioshin is over 5 million years, making a Kaioshin generation about that long.]

65 MILLION YEARS AGO?
--On Earth, the dinosaurs stubbornly refuse to go extinct.
[Ref: The series shows the dinosaurs still around on modern DB Earth. Of course, I’m assuming here that natural history in the Dragon World is remotely equivalent to the real world.]

MILLIONS, perhaps TENS OF MILLIONS OF YEARS AGO
--The evil wizard Bibidi has a son, Babidi. On their world “magic” is a science, and in time Babidi becomes a greater wizard than his father.
[Ref: Daizenshuu 7’s Babidi bio describes him as this old. Daizenshuu 4’s item guide describes Babidi’s home planet. Babidi says he’s better than his father in Chapter 458.]

Circa 5 MILLION YEARS AGO
The evolution of Earthlings
--On the planet Earth in the North Galaxy, Earthlings begin walking on two legs. In time, three distinct groups of Earthlings come about: Human-type, Animal-type (ie humanoid animals), and Monster-type (monster people and anything else not fitting into the other two categories).
[Ref: Kaioshin says in Chapter 545 that Boo was created when Earthlings were starting to walk on two legs, and Daizenshuu 7 places Boo’s creation circa 5 million years ago, roughly matching the real world development of homo sapiens. The Earthling classification system is from Daizenshuu 4. I’ve thrown it in here for the hell of it.]

Majin Boo is born
--By accident, the wizard Bibidi creates a fearsome Majin [magical creature], which he names “Boo”. Lacking both reason and emotions, Boo devotes himself purely to destruction. He is an incomplete creation who not even Bibidi can fully control. [Nevertheless, Bibidi decides to use Boo to overthrow the Kaioshins and take control of the Dragon World, and] the two begin destroying planets.
[Ref: Kaioshin describes Boo’s creation in Chapter 445 and Chapter 508. Bibidi’s own motives for having Boo destroy things is never specified in the manga, but Babidi wants to use Boo to become king of the world, and in DBZ Episode 277 Bibidi says he won’t be taking orders from the Kaioshins anymore, so I’m guessing based on that.]

--Over the course of just a few years, Boo destroys hundreds of planets. Eventually Bibidi and Boo come into conflict with the Kaioshins. First, the North and West Kaioshins are killed by Boo. Then Boo absorbs the South Kaioshin, the strongest and burliest Kaioshin of that generation. Next he absorbs the kindhearted and gentle Grand Kaioshin. As a result, Boo takes on the Grand Kaioshin’s fat appearance, and becomes weaker but more easily controllable. The only Kaioshin left afterwards is the current East Kaioshin, who despite being the youngest and weakest one, somehow survives with only heavy injuries. He and his attendant Kibito start waiting for an opportunity to defeat Bibidi.
[Ref: Still from Chapter 445 and 508.]

--Though Boo is now more easily controllable, he still gives Bibidi so much trouble that Bibidi has to seal him within a magic ball when not using him. He transports Boo from planet to planet in this ball, and eventually targets the planet Earth. After bringing Boo’s ball to Earth, the East Kaioshin takes this opportunity to kill Bibidi before he can remove Boo’s seal. East Kaioshin and Kibito decide not to attempt to destroy the ball or move it, fearing that any shock will release Boo. Since the ball is located in a place inaccessible to the primitive Earthlings, the two decide to leave it as-is.
[Ref: Chapter 445-446]

MILLIONS OF YEARS AGO?
Evolution of the Saiyans
--According to one theory, the race later known as the Saiyans evolve from Oozaru [Giant Monkeys] on an unknown planet hypothetically dubbed “Planet Saiya”. As a result, the modern Saiyans retain the ability to revert to their ancestral Oozaru form when exposed to “Bruits Waves”, a kind of energy found in sunlight when it is reflected off a moon.
[Ref: The theory about Saiyans evolving from Oozarus and “Planet Saiya” are from GT Perfect File Vol.1, page 74; the book itself literally calls this "a theory". The Bruits Wave stuff is from Chapter 232. I’m assuming Saiyans evolved on a similar timetable as Earthlings.]

Roughly 75,000~37,500 YEARS AGO?
The current generation of Kaios are born
--The North Kaio in time invents the “Kaio-Ken” [Fist of the Kaio] technique to multiply one’s own power, and the “Genki-Dama” [Vitality Ball] technique to draw power from one’s surroundings, but is unable to master these techniques himself.
[Ref: In the SEG: Character Volume Toriyama says the average lifespan for a Shinjin is 75,000 years (presumably he means regular Shinjin, not Golden Fruit ones, since the Kaioshins are shown to live much longer). So the current crop of Kaios probably isn’t older than that; I’m guessing they’re about middle aged. North Kaio’s invention of the Kaio-Ken and Genki-Dama comes from Chapter 211 and his Daizenshuu 7 bio.]

--DBZ Movie 9: Bojack, a survivor of the “Hera Clan”, rampages throughout the four galaxies. To safeguard their domains, the Kaios of the North, South, East, and West therefore combine their powers to seal Bojack away inside a planet at the edge of the universe. To maintain this seal, all four Kaios must be alive.
[Ref: This is the background to DBZ Movie 9. North Kaio merely says that these events were “long ago”, so I’m arbitrarily placing it here, since if nothing else it couldn’t have been before the current crop of Kaios were born. Bojack’s connection to the “Hera Clan” is extra background information created for the movie, and mentioned in passing in Daizenshuu 7.]

TENS OF THOUSANDS OF YEARS AGO
--DB Episode 153: On Earth, the deity Annin begins managing the Furnace of Eight Trigrams, located on the Mountain of Five Elements. The smoke of this furnace connects the living world to the afterlife. In recognition of her services, Annin takes on the modest title “Taijo-Rokun” [Grand Supreme Elder Lord].
[Ref: in the episode, Annin tells Goku she’s had her furnace-managing gig for tens of thousands of years. This prompts Goku to say that she’s an old lady, which makes her furiously angry. Hilarity ensues.]

11,000 YEARS AGO?
--Following the dinosaurs’ bad example, on Earth the saber-tooth tigers likewise refuse to go extinct.
[Ref: The series shows them still present on Earth in the modern era. The date here is when real saber-tooth tigers were nice enough to die off, according to Wikipedia.]

10,000~3,000 YEARS AGO? (#BA)
--The Saiyans begin a violent and inhumane lifestyle, attacking numerous planets to build up wealth and goods. According to one theory, the Saiyans descend from the survivors of an ancient battle, which explains their warlike tendencies.
[Ref: The Saiyan lifestyle description is from SEG: Character Volume. Toriyama says there that the Saiyans have lived this violent way “since ancient times”. The theory on their origins is from the Daizenshuu 7 race section, which says this is "possibly" the case. The range I’ve suggested here is I think suitably ancient, but otherwise arbitrary.]

Circa 6,233 BEFORE AGE
--DBZ Episode 196: In the North Galaxy, the hero Migoren fights bravely with an evil alien. In recognition of his deeds, after his death he is allowed to keep his body in the afterlife, and trains on the Grand Kaio’s world.
[Ref: DBZ Episode 196 places this 7,000 years ago (due to a typo, the Funi subtitles say "700 years"). The date of Migoren’s actual death is unspecified.]

Circa 4,250 BEFORE AGE
--DB Movie 2: The “Sleeping Princess” gem, a source of seemingly limitless power, becomes dormant. Demons store it within Devil’s Castle, awaiting the day it will become active again. Over the centuries, stories of this gem somehow morph into legends of a literal sleeping princess kidnapped by demons and imprisoned within Devil’s Castle. According to this story she continues sleeping for thousands of years inside a dark room, blinding all who look upon her with her great beauty.
[Ref: This is the movie’s back-story. Lucifer says the Sleeping Princess is awakening after 5,000 years.]

4,237 BEFORE AGE
--DBZ Episode 108: Planet Makyo approaches Earth, and some of its inhabitants immigrate to Earth. Known as the “Demon Clan”, their descendants include Garlic and his son Garlic Junior.
[Ref: This date is from Daizenshuu 7. The Garlic Junior filler arc establishes that Planet Makyo passes by Earth once every 5,000 years, and so this date is exactly 5,000 years before Age 763, when the Garlic Junior arc is set.]

--DBZ Episode 41: Raichi and Zarkuro claim that the ruins on their fake Planet Namek date to around this time.
[Ref: In the episode they say the ruins are 5,000 years old, but of course they are not real. However, since the ruins contain drawings resembling Rachi and Zarkuro’s true forms, possibly the illusionary ruins are based off their own memories of ruins on their home planet. I guess.]

Circa 2,733 BEFORE AGE
--DBZ Episode 196: In the North Galaxy, the hero Sarte protects his home planet from a meteor impact. In recognition of his deeds, after his death he is allowed to keep his physical body in the afterlife, and to train on Grand Kaio’s world.
[Ref: The episode sets Sarte’s deeds as 3,500 years ago, though the date of Sarte’s death is unspecified.]

Roughly 1,700~1,600 BEFORE AGE?
--On Earth, a form of Buddhism may have been founded around this time.
[Ref: References to Buddhism pop up occasionally in DB. In Chapter 1 Goku wonders if Bulma is collecting the Dragon Balls to make a Buddhist prayer necklace, in Chapter 44 Namu says a Buddhist chant while attacking Goku, and in Chapter 45 he says he believes in the Buddha. Buddhist prayers also turn up in Chapter 59 and Chapter 168. Daizenshuu 7’s world section explains that there is a form of Buddhism in DB Earth. In the real world Buddhism was founded around 500-400 BCE. I’m arbitrarily and perhaps absurdly assuming this is true in DB too; the year range here is based off the conversion of Age years to the Gregorian calendar, as explained below.]

1,235 BEFORE AGE (1 A.D.)
--The Dragon World’s equivalent of the Gregorian calendar begins. This year is equivalent to 1 A.D. Though this calendar is used in Penguin Village and certain other parts of DB Earth, exactly what it commemorates is uncertain. Perhaps not unrelated though, a form of Christianity does exist on DB Earth, with crosses and crucifixes sometimes seen.
[Ref: Daizenshuu 7’s glossary refer to the Western/Gregorian calendar being used on DB Earth, and its “world” section explains that a form of Christianity exists there too. Arale’s Daizenshuu 7 bio says she was made in Age 745. Since Dr. Slump establishes Arale as being made in 1980 A.D., this by extension makes 1 A.D. equivalent to 1,235 Before Age. In Chapter 99 Upa imitates the shape of a cross to scare the vampire Dracula Man, and a crucifix and cross-shaped tombstones are seen in DBZ Movie 12. Perhaps though this is ultimately something it is best not to think too much about.]

Roughly 750~250 BEFORE AGE?
--In the afterlife, Mister Popo is born. Sometime later he is dispatched to Earth to assist the planet’s god.
[Ref: Popo’s Daizenshuu 7 bio says his exact age is uncertain but that he’s over 1,000. I’m assuming this means he’s not older than 2,000, and estimated his birth as between roughly 1,000 to 1,500 years prior to his first appearance. In Chapter 244 Goku says Popo has been at God’s temple for “longer than even the current God or the one before that.” Popo’s origin in the afterlife and role on Earth are explained in Daizenshuu 7’s world section.]

739 BEFORE AGE
--DBZ Episode 14: The giant serpent Jado-Shin, god of the Serpent Road, sets up shop along the road’s halfway point. She disguises herself as the beautiful “Serpent Princess” and tempts any man who passes by.
[Ref: The date is from Daizenshuu 7. In the episode Jado-Shin says she’s been haunting the Serpent Road for 1,500 years, so this is that many years before Age 761, when Goku meets her.]

Circa 239 BEFORE AGE
--A “Super Saiyan” appears in this era, according to a Saiyan legend which states that one such supreme warrior appears every thousand years. The legend describes the Super Saiyan as making the universe tremble with destruction and slaughter.
[Ref: The date is from Daizenshuu 7. In Chapter 280 Vegeta says one Super Saiyan appears every thousand years, so this is that long before Age 762, when Goku becomes one.]

--Episode of Bardock: The Saiyan Bardock is sent backwards in time during the destruction of Planet Vegeta, arriving on Planet Plant (Planet Vegeta’s original name) apparently long before the Saiyans arrived there. When the planet is attacked by the space pirate Chilled, Bardock transforms into a Super Saiyan and defeats him. Dying, Chilled tells his underlings to warn his clan about “Saiyans with golden hair”, perhaps helping to give rise to the legend of the Super Saiyan.
[Ref: A summary of Episode of Bardock. The story itself never says how far back in time Bardock goes, so he could be many thousands, even millions of years in the past. But I’ve chosen this as the least arbitrary date. The story leaves unanswered why Chilled’s descendant Freeza doesn’t know Super Saiyans have gold hair.]

237 BEFORE AGE
--DBZ Episode 117: A sea turtle is born. This turtle will go on to learn human language, and eventually live to be over 1,000 years old.
[Ref: In the episode (set in Age 763) he celebrates his 1,000th birthday.]

Circa 226 BEFORE AGE
--DBZ Movie 13: In the South Galaxy, on Planet Conuts the people are protected by a Majin [demon god] which sucks up evil ki. The spectral body of this Majin resides within a gigantic sacred statue. Thanks to its protection, the people of Conuts live peacefully, until one day a group of evil wizards arrive on the planet. They use their magic powers to transform the Majin’s spectral body inside the statue into an evil Phantom Majin, which they call “Hildegarn”. Hildegarn breaks out of the statue and rampages through Conuts. The God [of Conuts] gives a pair of sacred flutes to the brothers Tapion and Minoshia, the sound of which weakens Hildegarn. As Tapion and Minoshia play their flutes, a priest cuts Hildegarn in two with a sacred sword. Hildegarn’s upper half is sealed within Tapion, and its lower half is sealed within Minoshia. To prevent Hildegarn’s halves from combining again, the brothers are sealed within magic music boxes and set adrift in two different galaxies. One of the wizards who created Hildegarn, Hoi, survives and begins searching for the music boxes.
[Ref: This backstory comes from the movie itself and from the movie’s Jump Anime Collection book, in the section “The Legend of Planet Conuts”. The movie establishes these events as 1,000 years ago, so this is that long before Age 774. The exact nature of the god who gives Tapion and Minoshia the flutes isn’t specified; I’m assuming it is the God of Conuts.]

Circa 50 BEFORE AGE
--In the afterlife, the Cat Sage Karin is born sometime in this era. He is later dispatched to Earth to assist the planet’s god, acting as an intermediary between God and the general population.
[Ref: In Chapter 88 Karin says he is “a little over 800.” Karin’s origin and role are explained in Daizenshuu 7’s world section.]

--On Earth, the Monster-type Earthling “Mummy-kun” is born. He goes on to live (?) for over 800 years.
[Ref: The date is from his Daizenshuu 7 bio, and his age (in Age 750) is given as 800 in the Boken Special. The classification “Monster-type Earthling” is from Daizenshuu 4.]

AGE 1 (#AGE)
--The first year of the “Age” calendar, the predominant calendar used on Earth. Presumably, something important happened this year. What could it have been? I dunno.
[Ref: The “Age” calendar being predominant on DB Earth is from Daizenshuu 7’s glossary. There remains no official explanation for what if anything the calendar commemorates.]

Roughly AGE 1~400?
Karin sets up shop
--Sometime during these centuries, the Cat Sage Karin arrives on Earth and takes up his role as intermediary between Earth’s God and its people. He sets up shop in the tower linking the Earth’s surface to God’s temple, so that all who wish to meet God must first get his approval. God’s temple itself floats in the sky far above the tower, and can only be reached via the “Nyoibo” [As-You-Will-It Staff], which expands and contracts according to a person’s thoughts. Also at the tower’s top is the gigantic “Kinto-Un” [Somersault Cloud], a cloud which flies at supersonic speeds and can be stood on only by those with pure hearts. Karin allows people to break off chunks of his huge Kinto-Un to use as their own personal vehicles.

The Super Holy Water and the Super God Water
--In addition, Karin offers anyone who climbs the tower “Super Holy Water”, which is supposed to greatly raise one’s power, but those who want it must grab a jug of it from him. In truth the “Super Holy Water” is ordinary rain water. The act of grabbing the jug from Karin is his way of training people, and it is this that makes them stronger. However, Karin also keeps a genuine power-up item, the “Super God Water”, a deadly poison. By overcoming the effects of this poison, a person can draw out their dormant power…if they survive. Over the years Karin allows 14 people to drink the Super God Water, all talented martial artists, but all die of the poison. In time Karin becomes a legend on Earth, known as a “god of the martial arts”, and his tower is named “Karin Tower” in his honor. The deep forest in which the tower is located is likewise known as the “Holy Land of Karin”, and the tower’s base is protected through the generations by a tribe that lives in the forest.
[Ref: The information on Karin is from Chapter 85, 89, 151, 152, 162, and Daizenshuu 7. No exact date is ever given for this, but as noted above Karin is born around 50 Before Age and is apparently well-known by Kame-sennin’s time, around Age 460. In Chapter 88 Karin says Kame-sennin was the only one prior to Goku to climb his tower, but in 151 he says he’s given the Super God Water to 14 people. I suppose it’s possible though that he gave it to people who didn’t climb the tower, for some reason.]

AGE 176
--The Monster-type Earthling Dracula Man is born. A vampire, he goes on to live (?) for over 500 years.
[Ref: The date is from his Daizenshuu 7 bio. However, the Boken Special gives his age (circa 750) as only 34. Perhaps 34 was his age at death, before he became undead? The classification “Monster-type Earthling” is from Daizenshuu 4.]

Circa AGE 250 (#200)
--Uranai Baba [the “Fortunetelling Granny”] begins her fortunetelling and divination business. In time she becomes renowned enough to charge exorbitant rates for her services. For her own amusement, those who cannot pay she allows to fight against five warriors she keeps in her employ. If the challengers win she’ll divine for them free of charge. Mummy-kun and Dracula Man are among those she hires to fight for her.
[Ref: The date is from Daizenshuu 7. In DB Episode 70, Kame-sennin says his sister has been divining for 500 years, so this is that long before Age 750. The explanation of her business is from Chapter 98.]

AGE 261
A weather anomaly devastates Planet Namek, wiping out virtually all of the Namekians
--Katatz, a Dragon Clan Namekian, sends his child out into space in a ship to escape the disaster. Katatz planned on joining his child, but dies before he can make his own escape. Eventually, the child’s spaceship crash lands on Earth, in the desolate Yunzabit Highlands. Perhaps as a result of these traumatic events, Katatz’s child loses all memory of his home world, and believes his spaceship to merely be a house. However, Katatz had left him a note saying to wait for him, so the child dutifully stays put.
[Ref: Kaio explains the disaster on Namek in Chapter 243, saying it was “a long time ago.” More information is given in Chapter 244 and 265. The date here (about 500 years before the Namek story arc) is from Daizenshuu 7, though Daizenshuu 4 estimates the event as 300~400 years ago. Piccolo Daimao's initial rampage was about 300 years before the series (more on this later), putting a lower limit on things.]

--DBZ Move 4: During the disaster on Namek, another Namekian escapes to the planet Slugg. This child is a mutant “Super Namekian”, born with a heart of pure evil. He eventually takes on the name “Slugg” himself, and becomes leader of the local “Demon Clan” that inhabits Planet Slugg.
[Ref: The background to DBZ Movie 4. Slugg’s “Demon Clan” henchmen being the natives of Planet Slugg is apparently from the pamphlet passed out during the movie’s premiere.]

The Great Elder (Age 261)
--On Namek itself, only a single survivor is left. Namekians reproduce asexually by laying eggs from their mouths, and so this sole survivor goes on to gradually repopulate the planet. Over the next 500 years he gives birth to over 100 children, becoming known as the “Great Elder”. As a testament to the knowledge and power of the Namekians, the Great Elder creates a set of Dragon Balls. When these seven Dragon Balls are assembled, they summon the dragon Polunga (Namekian for “God of Dreams”), who grants any three wishes within his power. Afterwards the Dragon Balls scatter across the planet and become ordinary stones for the next 130 days.
[Ref: In Chapter 260 Dende explains about the Great Elder and says he is the Great Elder’s 108th child, and in Chapter 243 Kaio says there are a little over 100 Namekians on Namek now. In Chapter 265 the Great Elder explains the meaning he assigns the Dragon Balls, Chapter 292 explains the name “Polunga” and the number of wishes, and Chapter 329 explains about 130 days, which in DBZ Episode 107 is said to be the length of a Namekian year. Despite the Namekians reproducing asexually, I’m going to refer to them as males. Sue me.]

Enma Daio crosses the Serpent Road (Age 261)
--DBZ Episode 14: The god Enma Daio, judge of the dead, travels to North Kaio’s planet along the Serpent Road [to train in the martial arts so that he can be strong enough to subdue unruly spirits]. Along the way he meets the Serpent Princess. He resists her temptation and continues on his way, but she falls in love with him.
[Ref: In the episode the Serpent Princess says Enma came by 500 years ago, so this is that long before Age 761. It’s never explained exactly why Enma went to Kaio’s, but presumably it was to train, and the most likely reason he’d need to train would be for his job.]

Circa AGE 281~291
--In Yunzabit Highlands, the child of Katatz finally gives up waiting for his parent to come. He abandons his spaceship and Yunzabit, traveling out into the world. As he learns more about Earth he realizes in retrospect how strange his “house” is, but he never considers that he might be from another planet. Periodically he returns to Yunzabit to check on his “house”, but nothing ever changes.
[Ref: The God of Earth tells this to Popo in Chapter 244, saying he waited 20~30 years before giving up.]

AGE 430 (#400)
--Uranai Baba’s younger brother is born. He eventually becomes one of the greatest martial artists on Earth, taking on the titles “Kame-sennin” [Turtle Sage] and “Muten Roshi” [Invincible Old Master]. However, in his younger days he simply goes by the nickname “Kame-chan”.
[Ref: The date is from Daizenshuu 7 and the SEG: Character Volume. In Chapter 88 (set in Age 750) Karin tells Goku that Kame-sennin climbed Karin Tower about 300 years ago, making him at least that old. DB Episode 70 places Uranai Baba’s birth at least 180 years prior to her younger brother’s. Their parents must have been as long-lived as their children. Kame-sennin’s youthful name is from DB Episode 129. His birth name remains unknown.]

AGE 431
--Since abandoning Yunzabit, the child of Katatz had become a powerful martial artist, in no small part thanks to his natural talent as a Namekian. Learning of the God of Earth, he journeys to God’s temple and becomes God’s pupil, hoping to eventually inherit his title.
[Ref: The date is from Daizenshuu 7. These events are explained in Chapter 164, though there no time period is specified.]

--DBZ Movie 1: Roughly around the same time, Garlic (a descendant of the people from Planet Makyo who immigrated to Earth) also becomes God’s pupil. He and the child of Katatz compete over who will be the next God of Earth.
[Ref: The movie says Garlic rebelled 300 years ago, but not when Garlic first became God’s pupil. I’m assuming it was around the same time as Katatz’s child. If nothing else, Karin lends the Nyoibo to Kame-sennin around Age 450, meaning after that Garlic presumably couldn’t have reached the temple.]

Roughly AGE 431~461?
--DBGT: During his time training as God’s pupil, the child of Katatz is driven by racial memories to attempt to create a set of Dragon Balls. However, his first attempt is a failure. Though powerful, after granting a wish they scatter throughout the entire universe, and as a side-effect of their power the planet they are used on explodes after a year unless they are gathered again. Due to their power, they are dubbed the “Ultimate Dragon Balls”, but the child of Katatz and Mister Popo hide them away inside God’s temple so that they can never be used.
[Ref: The Ultimate Dragon Balls’ history is explained in DBGT Episode 1. Since Pilaf says the set was made prior to Katatz’s child splitting up into God and Piccolo, yet they are still stored inside God’s temple, the time frame here are the years between Katatz’s child reaching God’s temple and becoming God himself. The detail of why the Ultimate Dragon Balls destroys the planet is from GT Perfect File Vol.1.]

AGE 448
--DB Episode 129: By this time, Kame-chan had become pupil to Mutaito, the Earth’s greatest martial arts master at the time. He quickly forms a rivalry with another of Mutaito’s students, the man who in the future would be known as “Tsuru-sennin” [the “Crane Sage”]. In the middle of his training under Mutaito, the eighteen year old Kame-chan falls in love with a girl named Fan-Fan. Tsuru falls for her as well, and the two become rivals in love as well as martial arts.
[Ref: A summary of the episode; date from Daizenshuu 7. Kame-sennin’s age is given as 18, so this is the appropriate number of years after his birth. It’s not specified how long he has been training under Mutaito, but it’s been at least a while, and he’s already rivals with the future Tsuru-sennin.]

--DB Episode 129: While training at God’s palace, Son Goku travels from the future back to this time and learns about ki-control from Mutaito. He also meets the young Kame-sennin, and rescues Fan-Fan from young Tsuru-sennin.
[Ref: Likewise from DB Episode 129. The time-travel room Goku uses seems to be the same one Tenshinhan and co. later use in DBZ Episode 17, in which the time travel is ultimately revealed as only in the person’s mind. It’s therefore uncertain whether Goku actually travels into the “real” past. If nothing else, Kame-sennin seems to have no memory of meeting Goku in his youth.]

Sometime after AGE 448?
--DB Episode 82: The young Kame-sennin and Tsuru-sennin find a baby “Inoshikacho”, a monster combining the parts of a deer, boar, and butterfly. Despite their rivalry, they both raise the monster as a pet.
[Ref: As said in the episode. Since Inoshikacho isn’t around in DB Episode 129, I’m assuming they started raising it afterward.]

Roughly AGE 450 to AGE 453
--In search of even greater strength, the young Kame-sennin leaves Mutaito’s dojo and scales Karin Tower. At the top he begins trying to take the Super Holy Water jug from Karin, and finally succeeds after three years. During this time, Kame-sennin becomes fixated on the Nyoibo, and asks Karin to lend it to him. Karin eventually agrees, thinking that the staff will not be needed anytime soon, as there is no one else worthy of traveling to God’s temple. Kame-sennin also receives a chunk of Kinto-Un from Karin, which at the time he is able to ride.
[Ref: In Chapter 88 Karin says Kame-sennin climbed the tower about 300 years ago, and took 3 years to get the water. In Chapter 13 Kame-sennin says he got Kinto-Un from “God”, but in Chapter 152 Karin says he gave it to him (perhaps by “God” he had meant Karin, the “god of the martial arts”). In Chapter 4 Kame-sennin and Sea Turtle are surprised when Kame-sennin proves unable to ride Kinto-Un, so apparently he could ride it at some point. In Chapter 162 Karin tells of lending the Nyoibo to Kame-sennin.]

AGE 459
--Tsuru-sennin’s younger brother Tao Pai-Pai is born. [Though he trains in the martial arts], he makes his living as an office worker.
[Ref: The date is from Daizenshuu 7, while the Boken Special gives Tao Pai-Pai’s age circa 750 as 291, matching this. Tao Pai-Pai’s pre-hitman career as an office worker is mentioned by Toriyama in the Boken Special. I’m assuming though that he trained at least a little in the martial arts prior to starting up as a hitman, if only because “hitman” would be an odd career move if he had no prior fighting experience.]

AGE 461
--Though his death is near, the God of Earth refuses to recognize Katatz’s child as his successor, due to a trace of evil he senses within the Namekian’s heart. After further intense training, the child of Katatz successfully expels this evil, which flees to the Earth’s surface.
[Ref: As God explains in Chapter 164. The date is from Daizenshuu 7. The manga doesn’t specify a date other than that Kame-sennin was young then, but Chapter 88 establishes Kame-sennin is over 300.]

Garlic Junior rebels against God (Age 461)
--DBZ Movie 1, DBZ Episode 108: At around the same time, the aging God of Earth sees that Garlic only wants to become the next God for impure motives, and passes him over in favor of Katatz’s child. Garlic then raises an army of his fellow Demon Clansmen and tries to take God’s throne by force. Possibly at this time he also steals the “Aqua Water” from God’s temple. The mist form of this water (the Aqua Mist) amplifies the evil within people’s hearts, turning them into Demon Clansmen, [and Garlic uses this to increase the size of his army]. However, Garlic and his army are defeated by the God of Earth, and Garlic himself is sealed within a vessel which is stored within God’s temple.
[Ref: The back-story to the movie. The date is from Daizenshuu 7; the movie says this was 300 years ago, so this is that long before Age 761. The part about the Aqua Water/Mist is from DBZ Episode 108, which doesn’t specify Garlic’s motives for stealing the water, but presumably it was to make more Demon Clansmen to help him take over.]

The Child of Katatz becomes God of Earth, and Piccolo Daimao is born (Age 461)
--The current God of Earth finally dies, and the child of Katatz becomes the new God. Meanwhile, the evil he expelled from his heart becomes an evil mirror image of himself. This evil doppelganger names himself “Piccolo”, after the Namekian words for “another world”. Piccolo uses the Namekian asexual system of reproduction to lay eggs, which due to his evil nature hatch into a brood of mutants which he dubs “the Demon Clan”. Piccolo becomes their leader, and gives himself the title “Daimao” [“Great Demon King”]. All those killed by Piccolo and his demons are unable to pass on into the afterlife, and their spirits simply float through the air in pain. They plunge the entire Earth into terror, but the new God of Earth does not intervene. He knows that because he and Piccolo were originally one, killing Piccolo will result in his own death, and gods cannot commit suicide.
[Ref: Kame-sennin explains Piccolo’s rampage in Chapter 135, God explains Piccolo’s origin in Chapter 164, those killed by demons not passing on is in Chapter 162, and the meaning of Piccolo’s name is in Chapter 244. The SEG: Character Volume refers to Piccolo and his Demon Clan as “mutants”, offering the closest thing to an official explanation of why they look the way they do.]

Mutaito seals Piccolo Daimao away (Age 461)
--DB Episode 102: All of Mutaito’s pupils besides Kame-sennin and Tsuru-sennin die fighting Piccolo Daimao’s Demon Clan.
[Ref: As depicted in a filler flashback in that episode. In the manga it’s not clear if Mutaito ever even had any pupils besides Kame-sennin and Tsuru-sennin.]

--Kame-sennin, Tsuru-sennin, and Mutaito himself are defeated by Piccolo Daimao. Mutaito goes on to develop the “Mafuba” [Demon-Sealing Wave] technique, which he uses to seal Piccolo away inside an electric rice cooker inscribed with magic charms. However, Mutaito dies from the strain of using the technique. Kame-sennin drops the jar containing Piccolo to the bottom of the ocean so that he will never return.
[Ref: As explained in Chapter 135. Episode 102 depicts Mutaito spending a long time inventing the Mafuba.]

Sometime after AGE 461
The Founding of the Turtle and Crane Schools
--Kame-sennin establishes the Turtle School of martial arts. At some point, he sets up shop on a small island, in a house he dubs “Kame House”. He keeps a pet sea turtle who, over the centuries, he teaches to speak human language.
[Ref: Chapter 135 establishes that Kame-sennin was still a pupil of Mutaito’s during Piccolo’s rampage, so it must have been later that he established his own school. The bit about Sea Turtle learning to talk is from Daizenshuu 4’s “animals and monsters” section.]

--Tsuru-sennin likewise establishes the Crane School of martial arts. Seeing Piccolo’s might made him feel that justice was powerless before evil, and so he dedicates his school to training assassins. The specialty techniques of his school include “Bukujutsu” [Air-Floating Technique], which allows people to fly by manipulating their ki, and the “Kikoho” [Ki-Control Cannon], a powerful attack that eats up a huge amount of its user’s ki. Using the Kikoho shortens people’s lifespans, and some people even die from it.
[Ref: Tsuru-sennin’s past is from Chapter 135. The bit about Piccolo inspiring Tsuru-sennin to turn evil and train assassins is from his Daizenshuu 7 bio, though DB Episode 129 depicts Tsuru-sennin as a jerk even before Piccolo. Chapter 132 explains about the Kikoho, while Bukujutsu is identified as a trademark Crane School technique in Chapter 120, but in Chapter 153 Piccolo recognizes it and calls it by name, despite his sealing presumably pre-dating the founding of the Crane School.]

--The God of Earth begins teaching Mister Popo martial arts, and the Namekian language.
[Ref: Popo says in Chapter 167 that his martial arts skills come from what God taught him, and Chapter 244 shows that Popo learned Namekian from God. I’m assuming Katatz’s child only started teaching Popo this stuff after becoming God.]

--DB Episode 127: As part of his training under God, Mister Popo takes the holy crown of the Goro-Goro Mountains, which acts as a powerful lightning rod. This task teaches Popo how to move faster than lightning.
[Ref: In the episode, Popo says this was part of his training. I’m placing it here for the same reasoning as above.]

AGE 462
--DBZ Chapter 41: The aliens Zarkuro and Raichi claim to have met each other around this time.
[Ref: They say this happened 300 years ago, so this is that long before Age 762. Of course, the two are pretending to be Namekians, but it’s possible some of the personal details they give are true.]

AGE 467
--DBZ Episode 196: The North, South, East, and West Kaios all assemble.
[Ref: The episode says they last met 300 years ago, so this is that long before 767. Why did they all meet up? The episode doesn’t say; it’s tempting to suggest that this is when Bojack was sealed.]

AGE 470
The Earth’s Dragon Balls are created
--Acting on his Namekian racial memories, the God of Earth creates a set of Dragon Balls to foster hope and courage in Earth’s people, and as a last resort in emergencies. Mister Popo creates a stone model of “Shen Long” [the “Divine Dragon”], which God breathes life into. Shen Long splits up and is stored within the seven Dragon Balls. When all seven are assembled, then Shen Long appears and grants a single wish (within certain limits), after which the balls scatter across the Earth and become ordinary stones for one year.
[Ref: The date is from Daizenshuu 7’s bio for Shen Long. Chapters 1, 164, and 165 explain the origin and basic rules of the Dragon Balls. In Chapter 213 God speculates that his memories of Namek influenced him to make them.]

AGE 474
--By this time, Bibidi’s son Babidi had found his father’s notes and planned to resurrect Majin Boo, using Boo to take over the Dragon World. He uses his magic powers to manipulate strong warriors with evil hearts, making them into his servants. The most important recruit he gets is Dabra, the strongest being in the Demon Realm, and its so-called king. Dabra sends one of his underlings to investigate the Earth, the resting place of Boo’s ball. The investigation shows that there are no beings on Earth powerful enough to resist them. However, due to the extreme length of time Boo has been left sealed, a stupendous amount of untainted energy is needed to revive him. Apparently because of this setback, it is 300 years before Babidi and his followers’ plan to revive Boo goes into action.
[Ref: The date is from Daizenshuu 7. Chapter 449 mentions Dabra’s underling investigating Earth 300 years ago, so this is that long before Age 774 (translations of both the manga and the Daizenshuu 7 timeline tend to gloss over that Dabra himself didn’t personally investigate Earth). So Dabra must have been serving Babidi and Babidi must have been trying to revive Boo for that long, though it’s not specified exactly when they started. Chapter 446 mentions that the need for large energy to revive Boo is because of how long he’s been sealed. Chapter 447 explains about Dabra. Dabra’s relationship to the Makaios or Makaioshins, if any, is so far unspecified.]

Roughly AGE 500~650? (#500)
--Sometime during this period, Kame-sennin invents his trademark attack, an energy blast called the “Kamehameha”. He becomes famous as the only one in the world who can use it.
[Ref: Chapter 14 explains about the Kamehameha, and in Chapter 15 Kame-sennin says one must train for 50 years to learn it, so presumably that’s how long it took Kame-sennin himself. I’m assuming Kame-sennin hadn’t started training to learn it before Piccolo’s rampage (Piccolo Daimao doesn’t recognize the technique when Goku first uses it against him, and mistakes it for the Mafuba). In the Boken Special Toriyama is asked why Gyumao never learned the technique if Son Gohan did, and he says Gyumao isn’t the technique type, not that the technique hadn’t been invented yet, so presumably Kame-sennin finished it before training Gyumao and Son Gohan. We don’t know when that was, but Gohan was born in Age 658, so I’m setting that as the latest point. Rounding the edges off, I got this range.]

[Herms]

Roughly AGE 550~650?
By this time, the Earth was united under a single government
--The 43 countries throughout the world had become 43 regions of a unified nation ruled over by a Nation King. [Perhaps as a holdover from the earlier era though], individual national flags are still sometimes seen. The Earth’s capital is Central City, the location of the aptly named King Castle. North, East, South, and West City serve as metropolitan centers in their respective parts of the world, and West City in particular becomes known as the Earth’s most technologically advanced city.
--Sometime during this period, somebody gathers the Dragon Balls and uses them to become King of Earth. This and other details about the Dragon Balls are recorded within documents that eventually find their way into the hands of later Dragon Ball hunters such as Bulma and Pilaf.
[Ref: Chapter 148-149 first establish that DB Earth is ruled over by a single King. This King appears again in Chapter 393. Still, a US flag is seen in Chapter 60, and what looks like the flag of Libya in Chapter 393. The Earth having 43 regions comes from Chapter 153, and Daizenshuu 7’s society section explains that these used to be 43 separate countries, before the Earth became united. In Chapter 1 Bulma says she learned of the Dragon Balls by reading a document from “incredibly long ago”, and in Chapter 18 she likewise attributes Pilaf’s knowledge of the balls to them being described in old documents. The document Bulma describes in Chapter 1 says that someone who gathered the Dragon Balls before wished to be king. The world is a generic Ou-sama rather than Koku-Ou/”Nation King”, the term typically used for Earth’s King, but Daizenshuu 7’s society section says this was indeed the Nation King from 100 years back. The 100 years figure comes from Chapter 4, when Kame-sennin says he found the 3-Star Ball about 100 years ago, meaning the last time they were used must have been before that. The range here uses that as a lattermost limit and assumes about 100 years must have passed between the balls’ creation and this wish. Information on the cities is from Daizenshuu 4’s field section.]

Origin of Freeza’s clan? (roughly Age 550~Age 650?)
--A spontaneous mutation results in a descendant of the space pirate Chilled being born as one of the first of a new hybrid species with tremendous power. In time, the mutant’s son Cold and Cold’s son Freeza use their power to take control of many planets, gathering talented warriors from throughout the universe into a mercenary army under their rule.
[Ref: In the first issue of Viz’s Shonen Jump, released in January 2003, Toriyama says of Freeza’s species that “there aren't many of them, but perhaps they are a new hybrid species that came into existence from an accidental spontaneous mutation in our grandfathers' time.” My suspicion is that “our grandfathers’ time” is some typo or mistranslation and that Toriyama was talking about Freeza’s grandfather, because what relevance do “our” grandfathers have to the question? But there’s no way to know for sure. Still, I’m stubbornly going with what I think is right, though it’s difficult to date when Freeza’s grandfather’s time would be. How old is Freeza? He’s first mentioned in the Daizenshuu 7 timeline in 731, but already seems to have established his land shark business by then, and he looks the same when destroying Planet Vegeta in 737 as he does during the Namek arc in 762, though this is probably due to character design laziness more than anything (and his species might age in ways unnoticeable to us). Freeza’s interest in eternal life could suggest he’s getting on in years. I’m arbitrarily assuming Freeza’s race has an average lifespan not too different from Earthlings, placing the birth of Freeza’s grandfather roughly 100~200 years before Age 731. The explanation of how Freeza started up is from SEG: Character Volume. Chilled is from Episode of Bardock. If we assume Freeza’s race can live hundreds of years, it’s possible Chilled himself is Freeza’s grandfather and the original mutant.]

Circa AGE 550
--DBGT: Using [stolen] spaceships, the primitive Saiyans arrive on Planet Plant (also called “Planet Tsufru”), a scientifically advanced world inhabited by the brilliant Tsufruians. Planet Plant has high gravity (ten times that of Earth), making the Tsufruians very short, but allowing the Saiyans to toughen up their bodies. The Tsufruians at first approve of the Saiyans living there, but over the next few centuries the Saiyans evolve with surprising rapidity, gaining greater intelligence but also even stronger violent instincts.
[Ref: The date is from Daizenshuu 7 and the GT Perfect File Vol.1. These events are first mentioned in the DBZ OVA, then in GT, then in the OVA remake. Kaio first explains about the Tsufruians in DBZ Episode 20, but does not at the time describe the Saiyans as alien invaders to Planet Plant. The description here is based mainly off Baby’s from GT Episode 27 and the Perfect Files, plus DBZ 20. The OVA shows the Saiyans arriving in a single giant spaceship, but GT shows them arriving in many small ones, which I’ve gone with here. Since the Saiyans are described as very primitive at this time, I’m assuming they stole these ships.]

AGE 553
--Kame-sennin begins collecting dirty magazines. Eventually his collection includes “Bob and Margaret’s Forbidden Games”, a classic of erotic fiction. Perhaps as a result of this growing interest, Kame-sennin in time becomes unable to ride his Kinto-Un.
[Ref: Date from Daizenshuu 7. In the Boken Special’s guide to Kame House, Kame-sennin says he’s been collecting porn for 200 years. This is therefore that long before the Piccolo Daimao arc, the current storyline when the Boken Special came out. “Bob and Margaret’s Forbidden Games” is the book Kame-sennin has Goku and Kuririn read as part of their training in Chapter 31, which stars two characters with those names. The book’s actual title is from the DBO timeline.]

AGE 556
--DB Episode 149: Uranai Baba has her last cold for the next 200 years.
[Ref: In the episode she mentions not having had a cold for this long.]

Circa AGE 650 (#600)
--Kame-sennin picks up the 3-Star Dragon Ball from the bottom of the sea. Not knowing what it is, he makes it into a necklace.
[Ref: The date is from Daizenshuu 7. In Chapter 4 Kame-sennin says he found it about 100 years ago, so this is that long before Age 749, rounded up.]

AGE 650
The Tenkaichi Budokai is founded
--The Tenkaichi Budokai [“Strongest-Under-the-Heavens Tournament”] is created to determine the world’s martial arts champion. It is held in a martial arts temple in South City, on Papaya Island. The date of the tournament is always May 7th, and for the next century it is held once every 5 years. There are two other such world championships, as well as the Olympics, but the level of competition at the Tenkaichi Budokai far surpasses them.
[Ref: The year is from Daizenshuu 7. Chapter 33 says the tournament is held every 5 years, meaning it must have been going on for a century before the 21st tournament. The schedule is changed to 3 years in Chapter 112, following the 21st tournament. The tournament always being on May 7th is from Daizenshuu 4, but is based on Chapter 153, where Piccolo Daimao addresses the world on May 9th, two days after the 22nd tournament. Chapter 32 mentions Papaya Island and South City. The other two world championships and the Tenkaichi Budokai’s superiority to them are mentioned in Chapter 122. The Olympics are mentioned in Chapter 28; it’s possible the Olympics are one of the other two world championships Tenshinhan refers to.]

May 7th, Age 650
--The 1st Tenkaichi Budokai is held. The champion and runner-up are both unknown.
[Ref: The date is from Daizenshuu 7; the details are explained above. No information exists about who won the tournament, though Kame-sennin, Tsuru-sennin, Tao Pai-Pai, Dracula Man, and Mummy-kun are the only Earth martial artists known to be around at this time. Presumably Karin, Mister Popo, and God didn’t compete.]

AGE 658
--Son Gohan is born. He goes on to be Kame-sennin’s #1 disciple and a world-famous martial artist.
[Ref: The date is from Daizenshuu 7. On the other hand, the Boken Special gives his age circa 750 as 102, putting his birth in 648. Chapters 8 and 12 detail Son Gohan’s fame.]

AGE 662
--The Earth’s God discusses his personal history with Mister Popo for the first and only time, telling him about his childhood in Yunzabit.
[Ref: Date from Daizenshuu 7. In Chapter 244 Popo says it was 100 years ago, so this is that long before Age 762.]

Roughly AGE 680~AGE 710?
Son Gohan and Gyumao join the Turtle School
--Son Gohan begins training under Kame-sennin, becoming his #1 pupil, while the #2 pupil is the man who will later be known as “Gyumao” [Ox Demon King]. Kame-sennin has the pair undergo unorthodox training such as delivering milk on foot across a vast island. After his training is complete Son Gohan goes on to become a world-famous martial artist, known for using the Nyoibo (which he receives from Kame-sennin) as a weapon. At some point he fights Kame-sennin. To win, Kame-sennin is forced to use his deadly “Bankoku-Bikkuri-Sho” [International Surprise Palm] technique.

--Gyumao meanwhile eventually amasses a huge collection of treasure (including the 7-Star Ball), and takes up residence in a castle near the Mountain of Refreshing Scenery. Over the years, Gyumao kills many people who attempt to steal his treasure, gaining a fearsome reputation and becoming known as the “emperor of devils”.
[Ref: Gohan and Gyumao training under Kame-sennin is mentioned in Chapter 12. Gyumao’s back-story is in Chapter 11, and in Chapter 14 Kame-sennin says Gyumao killed people to protect his treasure. I’m assuming “Gyumao” is a title and not the guy’s real name. Chapter 30 mentions Gohan and Gyumao delivering milk. Dating the pair’s training under Kame-sennin is tricky. Gohan is officially born in 658, making him 79 when Goku is born. Gyumao’s daughter Chi-Chi is born the same year, so how old is he in comparison to Gohan? He doesn’t look that old when he first appears, but he could be like Tao Pai-Pai and retain a youthful appearance unusually long due to his martial arts training. On the other hand, by the end of the series he looks much older. I’m assuming Gohan trained under Kame-sennin sometime between his 20s to early 50s, while Gyumao was much younger, possibly just a boy when he started training. In Chapters 8 and 12 Yamcha and Gyumao realize Goku’s connection to Son Gohan by seeing the Nyoibo. In Chapter 50 Kame-sennin mentions using the Bankoku-Bikkuri-Sho against Gohan.]

Circa AGE 681
--DBZ Episode 9: An All-Purpose Capsule Robot Model C-6 is buried out in the desert southeast of West City while excavating the ruins of Nemuria.
[Ref: The episode establishes this as about 80 years ago. The desert’s location is from Daizenshuu 4’s map of DB Earth. Since this would be before the founding of Capsule Corporation, presumably the term “capsule robot” has no relation to Hoi-Poi Capsules. Certainly the robot doesn’t seem to have the ability to be stored as a capsule, which would have come in really handy in the episode.]

AGE 698
--The aptly-named “Carrotizer Bunny” is born. A rabbit-man, all those who touch him automatically turn into carrots, though he has the ability to change them back at will. His odd power leaves him hated by society, turning him evil. As a result, he eventually turns to crime, forming the “Rabbit Gang” and using his power to terrorize ordinary citizens.
[Ref: The date is from Daizenshuu 7. It’s based on the Boken Special, which gives his age as 51 when he appears. The Boken Special’s “Tenkaichi Dictionary” also speculates on his tragic (?) backstory, outlined above.]

Roughly Age 703~712? (#700)
--On Planet Plant, the Saiyan Nappa is born. By this time, the Saiyans had taken to classifying themselves into either “Elite” or “Low-Level” warriors based on their potential at birth. Nappa is classified as Elite, and becomes a member of the Saiyan nobility.
[Ref: Daizenshuu 7’s Nappa bio says he was in his 50s when he died, placing his birth in this range. Chapter 225 establishes that Nappa was a Saiyan Elite and member of the nobility. In Chapter 228 Vegeta explains about Saiyans’ warrior potential being judged at birth. The SEG: Character Guide outlines the simple Saiyan class structure. Since Nappa is called Elite and nobility, presumably this structure existed when he was born. However, it’s also possible the classes were established after his birth and Nappa was retroactively placed into this class system. The OVA suggests King Vegeta only became king after overthrowing the Tsufruians (Age 720-730), and judging a baby’s potential does sound like something the Saiyans would only do after setting up an organized planet-conquering business, after taking over Plant.]

--The Saiyan Bardock is probably also born around this time. Unlike Nappa, he is classed as a Low-Level Warrior.
[Ref: Bardock lacks an official age or birth year, and since Saiyans stay young long this makes estimating his age a crapshoot. However, since Raditz was probably 10~20 when Planet Vegeta was destroyed (more on this later), I’m going to assume Bardock had kids young and that he was 20~30 when Raditz was born, placing his birth around 690~710. I already had this year range set up for Nappa, so I stuck him in here. This would make him 25~34 when he died.]

--On Earth, Briefs graduates from the Science and Engineering Department of West City University, majoring in physical science. He then goes on to complete his doctorate in the Science and Engineering Department’s graduate program.
[Ref: The information is from Dr. Briefs’ Daizenshuu 7 bio. For the date, DB Online places Capsule Corporation’s founding in Age 712, so I’m assuming this wasn’t too long after he earned his doctorate. I already had this year range for Nappa and Bardock, so I stuck this here too. What a useful range this turned out to be. Less reliable sites sometimes say Briefs was born in the year 700. This is a rather extreme mistranslation of his Daizenshuu 7 bio’s statement that he is “the most successful man of the 700s”; ie the most successful man of that century.]

AGE 710 (#710)
--The martial artist Chapa is born. He eventually becomes good enough to win the Tenkaichi Budokai without his opponents even touching him. In recognition of his skill, he takes on the title “King Chapa”.
[Ref: The date is from Chapa’s Daizenshuu 7 bio. Chapter 114 explains about Chapa. It’s never quite spelled out, but “King” is apparently just something he’s called because he’s so strong; he doesn’t seem to actually be ruler of anywhere.]

--DBZ Movie 2: The 13th Tenkaichi Budokai is held, and Kame-sennin is the champion.
[Ref: In the movie Dr. Kochin believes Kame-sennin is the strongest man in the world due to him having won the Tenkaichi Budokai 50 years ago, before Uiro was sealed in ice (the movie is in 762). They don’t specify the tournament number, but calculating forward from the first TB in 650, this would be the closest one to Uiro being sealed away.]

AGE 712
The birth of Capsule Corporation
--Dr. Briefs founds the company after inventing the revolutionary “Hoi-Poi Capsules”. These are tiny, easily portable capsules capable of storing objects of any size by converting them into particles. Briefs becomes representative director and president of the company, which is headquartered in West City. In the following decades, the Hoi-Poi Capsule has an enormous influence on Earth society. Anything from refrigerators, cars, and even houses can now be stored in a capsule only a few centimeters long and carried anywhere. Capsule Corporation manufactures all sorts of goods capable of being converted into capsules, and becomes the Earth’s leading vehicle manufacturer. Even things not manufactured by them can be equipped with a particle-conversion system allowing them to be turned into capsules too. All of this soon makes Dr. Briefs one of the Earth’s richest men.
[Ref: The date is from DB Online, the timeline of which says Capsule Corporation celebrates its 250th anniversary in Age 962. The details are from Briefs’ Daizenshuu 7 bio, the Daizenshuu 7 section on Capsule Corporation on pages 202-203, and the Daizenshuu 4 technology and supernatural section. In Chapter 422 Bulma describes capsules as converting objects into particles, whatever the heck that’s supposed to mean. Gohan’s Great Saiyaman costume is then stored inside his wristwatch using the same principle.]

--DBZ Movie 2: From his laboratory in the Tsurumai-Tsuburi Mountains, the evil scientist Dr. Uiro schemes of using his advanced science to take over the Earth, restructuring humanity into an obedient cyborg race. However, a freak weather disaster seals him and his entire laboratory within an eternal wall of ice. The people attribute this to divine judgment. Uiro’s robotic assistant Dr. Kochin is left behind, and begins searching for a way to free his master.
[Ref: This is from the movie, which places these events 50 years ago, so this is that long before Age 762.]

AGE 714
--DBZ Movie 12: Romeo’s lover Julianne dies.
[Ref: Romeo says this was 60 years ago.]

AGE 715
--The Monster-type Earthling Pilaf is born. A wealthy man, he eventually dubs himself “Pilaf the Great” and becomes obsessed with taking over Earth. He uses his financial resources and supposed intellect (he fancies himself a brilliant scientist) to design robotic battle suits and other devices to aid him in this goal.
[Ref: The date is from Daizenshuu 7, based on the Boken Special placing his age circa 753 at 38. The information on his resources is from his Daizenshuu 7 bio.]

--The ninja quintuplets Murasaki, Aka, Kon, Cha, and Ao are born. Murasaki eventually joins the Red Ribbon Army and attains the rank of Sergeant Major.
[Ref: The date is from Daizenshuu 7. The Boken Special names Murasaki’s brothers and establishes that they are all the same age (which of course is implied by them being quintuplets).]

AGE 716
--DB Episode 150: Mt. Kiwi, a volcano in the southern portion of Earth, erupts. This event is believed to wipe out the legendary Fire-Eating Birds who live there, but one Fire-Eating Bird egg is left behind.
[Ref: The episode establishes this as 40 years ago.]

AGE 717
--The monster Giran is born. A natural roughneck, he eventually puts his strength to use as a professional bodyguard.
[Ref: The date is from Daizenshuu 7. Giran’s occupation is from the Boken Special. Note that Daizenshuu 4 classifies Giran as simply a “monster” rather than a “Monster-type Earthling” ala Pilaf or Mummy-kun (Buyon is also classed as a “monster”). Presumably the difference is sort of like the one between a regular pig and Oolong.]

--Dr. Slump: The inventor Senbe Norimaki is born in Penguin Village. Over the years he builds many inventions, though few of them make any sense.
[Ref: Senbe’s official DB birth year is Age 722, via Daizenshuu 7. However, Dr. Slump establishes him as 28 when he builds Arale, an event which Daizenshuu 7 places in 745. Essentially, they set it up so that Senbe is 28 when he meets Goku (in 750), rather than when he builds Arale. Though this contradicts Dr. Slump, it doesn’t contradict DB itself, which debatably could have different background for the Slump characters. Nevertheless, I’ve decided to move Senbe’s birth back to this date to make him 28 in Age 745.]

AGE 719
--Man-Wolf is born. The opposite of a Wolf-Man, he’s a wolf who turns into a man during the full moon. He eventually finds gainful employment at a zoo, and becomes a 30-Dan Kempo master.
[Ref: The date is from Daizenshuu 7, his job from the Boken Special, and his Kempo rank from Chapter 119.]

Circa AGE 720~730 (#720)
The Saiyan/Tsufruian war
--DBGT: On Planet Plant, though the Saiyans have greatly multiplied over the last few centuries, their numbers are still relatively small, and the Tsufruians make up the majority of the planet’s population. A brilliant Saiyan tactician named “Vegeta” unites the Saiyans in a war against the Tsufruians. While the Tsufruians blame the war on the Saiyans’ increasingly violent instincts, some Saiyans claim the Tsufruians had been using them like slaves; the exact reasons are unclear. The two races rush into all-out conflict, with the Tsufruians countering the Saiyans’ natural physical advantage with their advanced technology, including laser blasters and “Scouters”, devices capable of numerically measuring an opponent’s strength. However, the Tsufruians had miscalculated the speed of the Saiyans’ evolution, and soon find themselves cornered.
[Ref: The date is from Daizenshuu 7 and GT Perfect File Vol.1. The description is a mix of that found in DBZ Episode 20, Toriyama’s memo on the Tsufruians, the OVA (which includes Vegeta’s claim that the Tsufruians used the Saiyans like slaves), and GT Episode 27. In Chapter 196 Raditz says the Saiyans had always had a low population.]

--DBZ Episode 20: The tide of the war truly turns during the full moon, which on Planet Plant occurs only once in eight years. When reflected by a planet’s moon, starlight contains an energy called “Bruits Waves”, which are measured in units called “Zeno”. During a full moon, moonlight contains over 17 million Zeno, and when Saiyans absorb this through their eyes it triggers a reaction in their tails which transforms them into Oozarus until either the full moon is gone or their tails are cut off. The transformation increases their power ten-fold, giving them an obvious edge and allowing them to more quickly take control of the planet.
[Ref: The once-in-8-years full moon and its effect on the war is from the episode. Vegeta explains about the Oozaru transformation in Chapters 232 and 233.]

The birth of Baby and Hatch-Hyack (circa Age 720~730)
--DBGT: On the brink of destruction, the Tsufruians use their remaining scientific power to develop a parasitic life-form to one day take revenge on the Saiyans. The Tsufruian King inserts his own genes into the cells of this life-form, which is then launched into space.
[Ref: As described in GT Episode 27.]

--OVA: During the war, The Tsufruian scientist Dr. Raichi creates Hatch-Hyack, a “hatred-amplification device” he intends to use as a weapon to eradicate the Saiyans. Raichi is killed by Oozaru Saiyans, and Hatch-Hyack is launched into space with Raichi’s corpse inside.
[Ref: As shown in the OVA. Daizenshuu 7 places it during this time.]

Founding of the Saiyan empire (circa Age 720~730)
--DBGT: The Tsufruians are finally wiped out, and the Saiyans take complete control of Planet Plant, which they rename “Planet Vegeta” after their leader. At the same time, Vegeta himself becomes the Saiyans’ official king, establishing a royal household.
[Ref: From GT Perfect File Vol.1. King Vegeta only becoming king and establishing a royal household after the Tsufruians are wiped out is from Daizenshuu 3 page 122, which details anime-only Saiyan backstory.]

--The Saiyans absorb Tsufruian technology, most notably the Scouter. Perhaps at this time, certain Saiyans become scientists. They use biotechnology to create the Saibai Men [“Cultivation Men”], living weapons with enough intelligence to understand basic orders. They can be grown almost instantly from seeds planted in the ground and watered with a special growth serum, and their power varies depending on local soil quality.
[Ref: The Saiyans absorbing Tsufruian technology is from Daizenshuu 7, and implied by Toriyama’s memo on the Tsufruians, which describes the Scouter as their technology. Toriyama’s memo on the Saibai Men describes them as made with biotechnology by Saiyan scientist(s). The other info is from their Daizenshuu 7 bio, which also records the “Saiyan scientists” thing. I’m guessing that their creation dates to this period, though it must be before 737 at the latest, since that’s when even better Saibai Men are introduced.]

--DBZ Episode 20: After destroying the Tsufruians, Saiyan technological and cultural progress stagnates. They therefore hit upon the idea of heading out into space and acting as mercenaries for rich aliens. In this way, they can receive wealth and new technology simply by fighting, which for them is killing two birds with one stone.
[Ref: As Kaio describes. The dating is from Daizenshuu 7.]

Raditz’s birth? (circa Age 720~730)
--Bardock’s eldest son, Raditz, is probably born around this time. He is a Low-Level Warrior like his father.
[Ref: Raditz has no official birth year, but per Chapter 196 he was old enough during Planet Vegeta’s destruction to have memories of his father and be sent out on missions like an adult. I’m therefore guessing he’s around 7 to 17 at the time and placing his birth here.]

AGE 721
--On Earth, the martial artist Namu is born in a poor village in the western part of the world. He becomes a Buddhist, and hones his techniques while working as a farmer. Practicing his “Tenku-Pekeji-Ken” [Heavenly X-Mark Attack] leaves X-marks etched into the village fields, perplexing his fellow villages.
[Ref: The dating is from his Daizenshuu 7 bio, his occupation from the Boken Special, which also features a rough comic by Toriyama showing Namu practicing his techniques, leaving marks on the ground that baffle others. The location of his village is from Daizenshuu 4.]

AGE 722
--The psychic Blue is born. He eventually becomes a general in the Red Ribbon Army.
[Ref: The date is from his Daizenshuu 7 profile, taken from the Boken Special placing his age circa 750 as 28.]

--Dr. Slump: In Penguin Village, Midori Yamabuki is born. She eventually becomes a middle school teacher.
[Ref: Midori’s official DB birth year is Age 727, as given in Daizenshuu 7, but like Senbe this comes from using her age at the start of Dr. Slump (23) to calculate backward from when she meets Goku in 750. However, she meets Goku several years after Slump begins. Like with Senbe I’m setting this back to make her age work with Daizenshuu 7’s date for Arale’s creation (745). The Daizenshuu 7 birth years for the other Slump characters are all fine.]

AGE 726
--The martial artist and underwear collector Ran-Fan is born.
[Ref: Date from Daizenshuu 7, her hobby from the Boken Special.]

AGE 730 (#730)
--[After centuries as an office worker], Tao Pai-Pai [gets fed up and] starts his own independent assassination business, utilizing his brother’s Crane School techniques. He eventually becomes the Earth’s #1 assassin, able to charge exorbitant sums.
[Ref: The date is from Daizenshuu 7. In Chapter 85 Tao Pai-Pai says he’s celebrating his 20th year as an assassin, so this is that long before Age 750. Toriyama mentions in the Boken Special Q&A that Tao Pai-Pai was a salaryman/office worker before becoming an assassin. I’m assuming he held this job for his entire century-long lifespan prior to becoming an assassin, just because it amuses me. Chapter 120 establishes his connection to Tsuru-sennin.]

--Dr. Slump: Taro Soramame is born in Penguin Village, while the psychic Tsuru-rin Tsun is born in Tsuba-Peppei.
[Ref: These are their Daizenshuu 7 birth years.]

AGE 731~762
Height of Freeza’s army
--By this period, Cold and Freeza’s army had spread throughout the entire universe. Freeza personally rules hundreds of planets, whose people he puts to work as mercenaries who attack planets with good environments so that they can be sold to rich civilizations. Freeza acts as the public head of this land sharking business, while his father Cold runs things from the shadows and is known to none save his family and direct subordinates. Freeza’s highest ranking subordinates are the Ginyu Special-Squad, an elite task force featuring five of only the best warriors from throughout the entire universe. Though there exists a space police force, they lack the military might to oppose Freeza. Even North Kaio becomes terrified of Freeza.
[Ref: Description of Freeza’s business from SEG: Character Volume; in the book’s Q&A Toriyama describes Freeza as ruling hundreds of planets (not counting the ones he destroyed). Info on Cold from his Daizenshuu 7 bio. Raditz first describes the “land shark” business in Chapter 197; Freeza’s involvement is first established in Chapter 246. The term “land shark” (ji-age) is used for Freeza’s business mostly in the guidebooks; it comes from the Japanese real estate boom, when unscrupulous businessmen and the mob used strong-armed tactics to buy up land they could then sell at a profit. Toriyama explains in Daizenshuu 2 that Freeza was inspired by such practices, which were at a high at the time. The description of the Ginyu Special-Squad is from Chapter 288. The space police are mentioned in passing in Daizenshuu 7’s glossary, in the entry on the universe. Kaio being scared of Freeza is from Chapter 261. The range here is just from when Freeza is first mentioned in the Daizenshuu 7 timeline (see below) to the year of the Freeza story arc.]

--DBZ Movie 5, JSAT Special: Other major members of the land sharking business include Freeza’s older brother Coola and his subordinates Sauzer, Neiz, and Dore, aka the Coola Armored-Squad. Ginyu, captain of the Ginyu Special-Squad, had originally competed to be captain of the Armored-Squad instead, but lost to Sauzer. Another rival of the Ginyu Special-Squad are the brothers Abo and Kado, whose special technique is to merge together into “Aka”.
[Ref: Basically from the movie and special. Ginyu competing with Sauzer is part of Sauzer’s extra background info, first mentioned in Weekly Shonen Jump No.25, 1991, shortly before the movie came out.]

Circa AGE 731
Freeza and the Saiyans join forces
--On Planet Vegeta, the Saiyans become part of Freeza’s land sharking business. Freeza rules the Saiyans by force, similar to a mob kingpin.
[Ref: The date is from Daizenshuu 7 and GT Perfect File Vol.1. This somewhat cramped timeline comes from having the team-up happen after the Saiyans wiped out the Tsufruians, and the OVA/GT’s depiction of Vegeta’s father King Vegeta as the one who led the Saiyans against the Tsufruians, placing all this within about one generation. The description of how Freeza ruled the Saiyans is from Toriyama Q&A in SEG: Character Volume.]

--Around the same time, King Vegeta takes a queen.
[Ref: From Daizenshuu 7. It’s apparently based on backtracking from Prince Vegeta’s birth in 762. Saiyans don’t waste time, it seems.]

AGE 732
--On Planet Vegeta, King Vegeta’s son is born. Clearly out of ideas, his father names him “Vegeta” as well. Under the hereditary monarchy King Vegeta established, his son accordingly becomes prince of the Saiyans. Prince Vegeta soon shows a considerable talent for fighting, and surpasses his father while still a child.
[Ref: Vegeta’s official birth year, featured in Daizenshuu 7, the GT Perfect Files, and SEG: Character Guide. The Bardock TV Special depicts Vegeta as several years older than Goku, though still just a little kid when he’s born. Nappa in Chapter 227 says Vegeta was named after Planet Vegeta, while the anime gives his father the name “Vegeta” as well, with the planet named after him, and the prince likewise named after his father by implication. The bit about hereditary monarchy is kind of self-explanatory, but is spelled out in Daizenshuu 3’s Saiyan page and Daizenshuu 7’s glossary. Vegeta’s early talent is mentioned in Chapter 247, and him surpassing his father as a kid is from Chapter 296.]

--On Earth, Lunch is born. For unexplained reasons, she has a physical peculiarity which causes her to switch between a gentle and violent personality whenever she sneezes. Eventually, her violent personality becomes an infamous criminal.
[Ref: The Japanese Wikipedia page for Lunch says an issue of Weekly Jump gave her age when she first appears as 17. I’ve decided to trust them and throw this date in here. No official source ever explains Lunch’s split personality.]

--Dr. Slump: Peasuke Soramame and Akane Kimidori are born in Penguin Village, while Tsuru-rin Tsun’s younger brother Tsuku-tsun Tsun is born in Tsuba-Peppei.
[Ref: From their Daizenshuu 7 bios.]

Roughly AGE 733~734?
--JSAT Special: On Planet Vegeta, King Vegeta’s second son, Tarble, is born. In contrast to his older brother, Tarble shows no talent for fighting. His father considers him an embarrassment, and eventually ships him off to a distant planet.
[Ref: The special gives no age for Tarble, but as Vegeta’s younger brother he must be born after 732, and he must have been shipped off before Planet Vegeta’s destruction in 737. He also has memories of Vegeta, so he couldn’t have been a baby when he was dispatched. Within this cramped time-frame, I suggest Tarble was born 1~2 years after Vegeta and was shipped off not too long before the planet’s destruction, around the age of 3 or 4.]

AGE 733
--In West City, Briefs’ daughter Bulma is born. She inherits her father’s genius intellect, along with the quirkier aspects of her parents’ personality.
[Ref: The date is from Daizenshuu 7 and SEG: Character Guide. In Chapters 2 and 5 Bulma says she’s 16, matching this. I’m assuming she was born in West City.]

--The desert bandit Yamcha is born. His early life is shrouded in mystery, mostly because nobody cares.
[Ref: The date is from Daizenshuu 7 and the SEG: Character Guide. The other bit is self-explanatory.]

--The martial artist Tenshinhan is born. A descendant of the Three-Eyed Clan, aliens who settled on Earth at some unknown point in the past, he has the natural ability to grow an additional pair of arms from his back, and to split up into four people. Oh, and a third eye, that too.
[Ref: The date is from Daizenshuu 7 and SEG: Character Guide. The bit about the Three-Eyed Clan is from Daizenshuu 4 and 7. It should be noted that Daizenshuu 4 still classifies him as an Earthling, albeit one with alien ancestry.]

May 8th, Age 733
--A kindhearted dog-man becomes the new King of Earth. Originally named “Mister Dog”, his marketing department quickly advises him to change his name to “Caesar”.
[Ref: The date is from Daizenshuu 7. DB Episode 113 shows a ceremony celebrating the 20th year of the King’s reign, so this is that long prior to May 8th, 753. The bit about Mister Dog/Caesar is from Eddie Izzard, who as far as I’m concerned is part of the DB canon.]

Circa AGE 735
--The Saiyans’ animosity towards Freeza begins to grow, and on Planet Vegeta there is continual civil unrest among the Saiyans.
[Ref: Date and info from Daizenshuu 7 and GT Perfect File Vol.1. I suspect this is a reference to the war-torn Saiyan city in DBZ Episode 17, but am not sure.]

--DBZ Episode 17: While training in God’s palace, Tenshinhan, Yamcha, Kuririn, and Chaozu travel back in time to this era. Travelling through a war-torn Saiyan city, they encounter two Saiyan survivors, Onio and Brocco. Though weak by Saiyan standards, the pair quickly kills the time travelers off one-by-one. Fortunately, this time trip was only in the mind, and the group returns safely to their own time.
[Ref: As mentioned above, I assume the “Saiyan civil unrest” stuff in Daizenshuu 7 refers to this episode, so I’ve placed this time trip here. Since Popo says the journey is only in the group’s mind, it’s unclear whether they travel to the “real” past. The names "Onio" and "Brocco" are from the Famicom game "DBZ: Saiyan Assault!!"; I used them because I like them.]

AGE 735
--The vagabond Yajirobe is born.
[Ref: The date is from SEG: Character Guide.]

--DBGT: While drifting through space, the parasitic life-form created by the dying Tsufruians swears vengeance against the Saiyans. It begins plotting not merely the eradication of the Saiyans, but a “Universal Tsufruization Plan” to revive the Tsufru race by converting all life-forms in the universe into Tsufruians.
[Ref: Date and info from GT Pefect File Vol.1.]

AGE 736
--The martial artist Kuririn is born in East Village. He has no nose, but a physical idiosyncrasy allows him to breathe all he needs via his skin.
[Ref: The exact date is from Daizenshuu 7 and SEG: Character Guide. In Chapter 41 Kuririn is identified as 13. In Chapter 25 Kuririn says he came from East Village; Daizenshuu 7’s places dictionary refers to it as his homeland, so I’m assuming he was born there. Toriyama mentions Kuririn’s physical idiosyncrasy in the Boken Special.]

--Future world martial arts champion Mark is born. He eventually achieves everlasting fame under his ring name, “Mister Satan”.
[Ref: Date from SEG: Character Volume, which is also where Toriyama reveals Mister Satan’s real name. Toriyama explicitly says the character has no family name and is simply named “Mark”.]

AGE 737
--Bardock’s second son, Kakarot, is born on Planet Vegeta. Like his father and older brother he is classified as a Low-Level Warrior.
[Ref: Date from Daizenshuu 7, DBZ Son Goku Densetsu, and SEG: Character Volume. In Chapter 2 Goku claims to be 14, but in Chapter 41 he says he is really 12 and had miscounted before. This is therefore 12 years before the series’ start. Chapter 197 reveals his origin, while the Bardock TV Special and Chapter 307 detail his father.]

--DBZ Movie 8: On the same day as Kakarot, the high-class Saiyan Paragus’ son Broli is born. Broli has astronomically high power even as a newborn, and King Vegeta fears he will be a danger to his own son’s position, so he attempts to have Broli and his father killed.
[Ref: Mostly from Paragus’ flashback in the movie. Paragus having a high position in Saiyan is suggested in the supplemental daizenshuu TV Animation Part 3, based on Paragus’ ability to meet directly with King Vegeta. It also suggests that Paragus may have been Bardock’s superior or otherwise known Bardock, due to him recognizing Goku as Bardock’s son.]

--Strengthened Saibai Men are introduced around this time. If grown in good soil their strength can rival that of a Low-Level Warrior, though their intelligence remains low.
[Ref: Date from Daizenshuu 7. It's taken from how the Bardock TV Special shows kid Vegeta sparring with Saibai Men, and a nearby lackey says they are a new, strengthened kind. Implicitly the ones Vegeta and Nappa use on Earth are this type.]

Freeza turns against the Saiyans (Age 737)
--Bardock Special: Freeza gains an interest in Planet Kanassa, possibly due to rumors of an energy there which grants psychic powers. A team consisting of Bardock and four other Saiyans are dispatched to take control of the planet, which they manage a month faster than expected. This feat by a group of nameless Low-Level Warriors adds to Freeza’s growing concern that the Saiyans are becoming too powerful.
[Ref: A summary of the special. The date is from Daizenshuu 7.]

--Freeza decides to annihilate the Saiyans. Officially, his reason is that more outstanding warriors such as Prince Vegeta are being born, and he doesn’t think the Saiyans will remain obedient if they get too powerful. Though the strength of individual Saiyans is not significant in comparison to Freeza’s, if they all joined together against him it might prove troublesome. Unofficially, Freeza is probably motivated by legends of the “Super Saiyan”, and wants to get rid of the Saiyans before such a formidable threat will emerge. He therefore decides to destroy Planet Vegeta and most of the Saiyans with it, though he decides to target the planet at a time when Prince Vegeta is not around, since he thinks the prince will be a useful servant.
[Ref: Date from Daizenshuu 7. The “official” explanation of Freeza’s motives, and why he spared Vegeta, is from Chapter 247. Chapter 285 introduces the idea that the Super Saiyan was what Freeza truly feared.]

--Bardock Special: Bardock develops precognitive powers after being attacked by Tooro, the last of Kanassa’s people. He is plagued by visions of Planet Vegeta’s impending destruction at Freeza’s hands. As Bardock heals from Tooro’s attack, the other members of his team are sent to conquer Planet Meat. While there, Freeza’s plan to eradicate the Saiyans goes into operation, with Freeza’s close aide Dodoria and his henchmen killing Bardock’s teammates. Bardock himself arrives on Meat shortly thereafter. He defeats Dodoria’s men but loses to Dodoria himself, and is left for dead. Recovering, he heads back to Planet Vegeta to try and warn the other Saiyans of Freeza’s betrayal, but nobody believes him.
[Ref: More summary of the special.]

Freeza destroys Planet Vegeta (Age 737)
--As a Low-Level Warrior, Kakarot is sent off to Earth, a frontier planet judged to offer no significant resistance. Thanks to the planet’s moon, it’s thought that Kakarot, though still a baby, will be able to wipe out the natives within a few years by taking advantage of the Oozaru transformation.
[Ref: Chapter 197 and 228. Earth is described as on the “frontier” (from the Saiyans’ perspective) in the Bardock Special, which also introduces the idea that Planet Vegeta was destroyed shortly after Goku’s birth.]

--DBZ Episode 78: At around the same time, King Vegeta starts a revolt against Freeza. He attacks Freeza with some of his underlings, but the entire group is effortlessly killed.
[Ref: A summary of the filler; date from Daizenshuu 7. In Chapter 296 Freeza mentions fighting the Saiyan king (who isn’t named in the manga) when he attacked the planet, but the idea that the king was the one to initially strike against Freeza is unique to the anime.]

--Freeza attacks Planet Vegeta. Bardock holds out against Freeza until the very end, but is no match. Planet Vegeta itself is wiped out, and all but a handful of Saiyans perish. Prince Vegeta is elsewhere (Freeza having purposefully struck when he wasn’t around), while Raditz and Nappa are off attacking a planet somewhere, and Kakarot is safely on his way to Earth.
[Ref: Bardock debuted in the TV Special but was later mentioned in Chapter 307 of the manga. Raditz explains Planet Vegeta’s destruction in Chapter 197, saying he survived because he was off attacking a planet with another Saiyan. The other survivor is described as if he was sent off as a baby like Goku was, which doesn’t match what we later learn of Vegeta or Nappa. Since the Bardock Special shows Vegeta on his own after the planet’s destruction, I’m assuming Nappa and Raditz were together. Freeza’s role in the planet’s destruction is revealed in Chapter 247. In Chapter 303 Freeza says he destroyed Planet Vegeta “about 30 years ago”, though this conflicts with Goku being about 25 at the time, going off of him being 12 at the start of the series.]

--Episode of Bardock: During Planet Vegeta’s destruction, for unknown reasons Bardock is catapulted backwards in time, into the era of Freeza’s ancestor Chilled.
[Ref: A summary of the special, which never explains why or how far back Bardock travels into the past.]

—DBO: The “pale man” Miira, a traveler from the future, saves Bardock from Planet Vegeta’s explosion. He brainwashes Bardock to serve him, and takes him into the future.
[Ref: Brainwashed Bardock appears in the game’s various Time Machine Quests. Obviously, this and Episode of Bardock are incompatible, at least not without more effort than I’m willing to give.]

--DBZ Movie 8: Though King Vegeta had left Paragus and Broli for dead, they barely survive. As Freeza destroys Planet Vegeta, Broli’s dormant power awakens, and he carries Paragus with him to safety. Paragus spends the rest of his life plotting revenge against King Vegeta.
[Ref: From Paragus’ flashback in the movie.]

--DBZ Movie 5: Freeza’s older brother Coola watches his attack on Planet Vegeta. He notices that one Saiyan, Kakarot, is getting away. However, he considers this Freeza’s problem and looks the other way.
[Ref: As shown at the start of the movie.]

Chi-Chi is born (Age 737)
--On the Mountain of Refreshing Scenery, Gyumao’s daughter Chi-Chi is born. Soon after, Chi-Chi’s mother dies from an illness.
[Ref: Date and info from Daizenshuu 7, though I’m assuming Chi-Chi was born in Gyumao’s castle. SEG: Character Volume likewise gives Chi-Chi’s birth year as 737. DB Episode 149 establishes that Chi-Chi’s mother has died, but doesn’t say when or why.]

June~August, Age 737
Kakarot reaches Earth
--On Earth, Kakarot is found by Son Gohan (now 79 years old), who believes the baby has been abandoned by his parents. Gohan adopts the child, giving him the name “Son Goku”. Though he seems cheerful enough at first, Son Goku soon displays the vicious personality characteristic of the Saiyans.
[Ref: As explained in Chapter 2 and 197. The date is from Daizenshuu 7. I’m not sure what the “June~August” bit is based on. Going by his official birth year, Goku must turn 13 sometime during Age 750, but at the 21st TB in May 750 he still considers himself 12. Possibly then, the idea here is that Gohan must have found Goku sometime after May in 737, and that Goku therefore considers his birthday as being sometime after May. But I’m just guessing. Baby Goku’s mean personality is mentioned in Chapter 197, though the Bardock Special shows him as cheerful from the start.]

—DBO: A youth from Age 1000 is briefly carried to this era by a time rift, and encounters Son Gohan and baby Goku.
[Ref: A description of one of the Time Leap Quests in the game.]

After AGE 737
--In the years following Planet Vegeta’s destruction, to keep the remaining Saiyans obedient Freeza spreads the story that their planet was destroyed by a meteor impact.
[Ref: Raditz gives this version of events in Chapter 197. In Chapter 247 Dodoria reveals Freeza’s role, and implies that the “meteor impact” thing was just a cover story. Daizenshuu 7’s glossary explicitly puts this idea forward.]

--DBZ Episode 20: Another story is that Planet Vegeta’s God had destroyed the planet to punish the Saiyans’ evil deeds.
[Ref: The version of events Kaio tells Goku in the anime. Perhaps he’s afraid of Goku going off to fight Freeza if he knew the truth?]

--DBZ Movie 3: Another Low-Level Saiyan, Tullece, is also lucky enough to escape Planet Vegeta’s destruction. Low-Level Warriors tend to look alike, and so Tullece looks identical to Kakarot. Eventually Tullece gets his hands on seeds of the “Shinsei-ju” [Divine Tree], a gigantic tree whose fruit only the gods are allowed to eat. When used in the living world, the Shinsei-ju completely sucks the nutrients from whatever planet it grows on, so that not even a single blade of grass will grow for over a hundred years. It uses these nutrients to produce fruit which if eaten vastly increase one’s power. By planting the Shinsei-ju on many worlds and continuing to eat its fruit, Tullece tries to acquire enough power to challenge Freeza. At the same time, he gathers a small army from throughout the universe: Daiz (prince of Planet Kaborcha), Kakao (a cyborg bounty hunter), Amond (a criminal imprisoned on Planet Nutz), and the twins Rezun and Rakasei (who Tullece revives from fossils of the Beanz People using Shinsei-ju extract).
[Ref: Akira Toriyama: The World Anime Special explains that Tullece survived Vegeta’s destruction “by luck”, and gives backstory for him and his henchmen. His reason for looking like Goku is touched on in the movie, and slightly expanded on in Daizenshuu 3’s page on Saiyans.]

AGE 738
--Baby Goku accidentally drops down a valley, taking a strong blow to the head. He survives thanks to his incredible life-force, but as a result he loses all notion of his Saiyan nature, and becomes sweet and easy-going. Sometime afterword, Son Gohan relates these events to Kame-sennin.
[Ref: As described in Chapter 197, which specifies only that Goku was a baby at the time. The exact date is from Daizenshuu 7. Kame-sennin mentions Gohan telling him about Goku in Chapter 15 and 197.]

--The psychic Chaozu is born. He eventually trains in assassination techniques under Tsuru-sennin.
[Ref: Date from SEG: Character volume. No date is ever given for exactly when he joins the Crane School.]

[Herms]

AGE 739
--Gyumao goes on a picnic, taking Chi-Chi (now 2 years old) with him. While out, a fire spirit falls down from the heavens and onto the Mountain of Refreshing Scenery, covering the entire mountain in flames. These flames prevent Gyumao and Chi-Chi from returning to their castle, and change the local climate to be hot and inhospitable. To reflect this change, the mountain is renamed “Mount Frypan”.
[Ref: Oolong explains Mount Frypan’s history in Chapter 11, saying it caught fire “about 10 years back”. In Viz’s translation, they change the opening narration for Chapter 15 to say that Gyumao and Chi Chi have been forced out of their castle “for months now.” The exact date and explanation of where Gyumao and Chi-Chi were at the time is from Daizenshuu 7.]

Roughly AGE 740~750? (#740)
The Red Ribbon Army forms
--The Red Ribbon Army was probably formed around this time. Essentially a giant criminal organization bent on world domination, it has a pyramid-style organizational structure. At its top is Commander Red, with Adjunct Black serving directly under him, and beneath them are various generals. As scientific advisor, the army employs the brilliant but mad Doctor Gero. In time the Red Ribbon Army obtains so much military strength that even the police and the Earth’s Royal Army cannot touch them, and their name becomes feared throughout the world. They also produce enough planes, submarines, tanks, etc to become one of the Earth’s leading producers of vehicles. To create even stronger soldiers for the Red Ribbon, Doctor Gero begins developing a series of androids. The first seven of these have various problems, but the eighth works well enough to be dispatched to the army’s northern stronghold, Muscle Tower.
[Ref: No date is ever given for when the RR formed, but by their first appearance in the series they are already well-established and world famous. In Chapter 72 Bulma and Kuririn freak out when they learn they’re after Goku, and in Chapter 97 Lunch says that the police couldn’t handle the RR. The DBO timeline has the Red Ribbon Army’s successors, the Red Pants Army being formed in 991, nine years before the game. I’ve arbitrarily assumed that the RR themselves were around for an equivalent amount of time before Goku fights them. Daizenshuu 7’s glossary entry for them describes them as a gigantic criminal organization, talks about their pyramid structure, and says the world government’s army couldn’t face them. Daizenshuu 7’s section on Capsule Corporation, pages 202-203, mention the RR’s role in vehicle production. Chapter 335 and the Daizenshuu 7 glossary explain Gero’s connection. The title page for Chapter 367 explains that Androids 1-7 all had problems (and were presumably not used). DB Tenkaichi Densetsu says the purpose of Androids 1-8 was to create stronger soldiers for the RR.]

AGE 740
--The Animal-type Earthlings Oolong and Puar are born.
[Ref: From their Daizenshuu 7 bios. In Chapter 5 Oolong says 16-year old Bulma is older than him, in Chapter 16 he describes himself as a “piglet”, and Chapter 8 shows that Oolong and Puar attended Shape-Shifting Kindergarten at the same time.]

--Wanting to get strong and become popular with girls, at the tender age of four Kuririn becomes a pupil at Oorin Temple and studies martial arts for the next eight years.
[Ref: Exact date from Daizenshuu 7. In Chapter 28 Kuririn mentions training at Oorin for 8 years. This leaves a year-long gap between him living Oorin and arriving at Kame-sennin’s in 749. Presumably the trip took him a year. Chapter 36 establishes Kuririn as 13, so no matter how you cut it he must have been incredibly young when he started training. He mentions his motives for studying martial arts in Chapter 25.]

--Sno is born in Jingle Village.
[Ref: From her Daizenshuu 7 bio. Her age isn’t specified in the series.]

--DBGT: Out in space, the Tsufruian parasitic life-form manufactures a “Machine Mutant” servant in order to gather the energy it needs to obtain a powerful body. The servant is called “Doctor Mu”, and is programmed with the method for developing further Machine Mutants. Doctor Mu begins creating the powerful Machine Mutant Llod, the planet-sized M-2, and various others. While taking care of the parasitic life-form, in time Mu begins to view it as his own offspring rather than his creator, and names it “Baby”. The parasite, understandably, hates this.
[Ref: Date from GT Perfect Files Vol.1. Most of this is explained at the end of GT Episode 22, but GT Perfect File Vol.1 adds a few more details. Despite how at the end of Episode 22 Baby and the narrator both flat-out say Mu was Baby's creation and not the other way around, it's still common to see fans refer to Mu as creating Baby, or say he’s an alien who happens to find Baby. Maybe it's some dub thing, or maybe people just fall asleep halfway through Episode 22 and never get the true information? Also in Episode 22, Baby says how much he hates it when Mu calls him "Baby", yet he still sticks with the name anyway for the rest of the series.]

AGE 744
--DBZ Movie 13: The wizard Hoi supposedly begins searching for the music box which Tapion is sealed inside.
[Ref: Hoi says he spent 30 years tracking the music box down, so this is that long before 774. Much of what Hoi tells Gohan and co. turn out to be lies though.]

Roughly around AGE 744~748?
--Son Gohan continues to raise Goku, training him in the martial arts and even giving him the Nyoibo. However, as a Saiyan Goku transforms into an Oozaru whenever he sees a full moon. Learning of this transformation, Gohan warns Goku that a monster comes out on the night of the full moon, and that to keep safe Goku must stay inside on those nights and never look at the moon. One such night though, Goku goes outside to pee, and catches a glimpse of the full moon. This time Son Gohan is killed by Oozaru Goku. Retaining no memory of what he does in his Oozaru state, the next day Goku finds Gohan’s dead body and assumes that the monster Gohan had told him about so often was to blame. He keeps the 4-Star Dragon Ball Son Gohan had found as a memento of his adopted grandfather, praying to it and even calling it “Grampa”.
[Ref: The Oozaru-related events are described in Chapter 21 and 233. In the Boken Special Toriyama explains why Goku assumed the monster was responsible for Gohan’s death. No specific date is ever given for this, but I’m assuming it was at least a year before Goku met Bulma, and rather arbitrarily assuming Goku was at least 7. Goku’s attachment to the 4-Star Ball is shown in Chapter 1, and in Chapter 12 Goku says Gohan gave him the Nyoibo (implying this happened when Gohan was still alive and Goku didn’t just take the staff after his death). On the flipside, in Chapter 108 Gohan is surprised Goku still has the 4-Star Ball, so apparently Goku was the one to attach so much importance to the ball.]

Roughly AGE 745~747?
--Oolong and Puar attend Southern Shape-Shifting Kindergarten. Oolong bullies Puar, but is eventually expelled due to stealing his teacher’s panties. This leaves his shape-shifting powers incomplete: he can only stay transformed for five minutes, and must then rest for a whole minute before transforming again. Puar meanwhile graduates properly from the kindergarten, becoming able to transform without any time limit. Oolong eventually uses his abilities to terrorize various small villages, extorting money and taking village girls as wives.
Ref: Oolong and Puar’s connection to the Shape-Shifting Kindergarten is mentioned in Chapter 8; Puar says they attended “long ago”. The limits of Oolong’s powers are gone over in Chapter 6, while in the Boken Special Toriyama says that Puar has no such limits because he graduated properly. The year range is from when the two were five (probably around when one might start kindergarten) to the year Puar meets Yamcha.]

AGE 745 (1980 A.D.)
--Dr. Slump: In Penguin Village, Senbe Norimaki creates a “perfectly human” robot. He names it “Arale Norimaki” and attempts to pass it off as his own 13-year old kid sister. Arale begins attending school, and meets Akane Kimidori and the brothers Taro and Peasuke Soramame. Her teacher is Midori Yamabuki, who Senbe eventually marries.
[Ref: Summarizing early Dr. Slump. The “Age” date for Arale’s creation is from her Daizenshuu 7 bio, while Dr. Slump shows that it begins in 1980. Daizenshuu 7 says the Age and Gregorian calendars are both used on DB Earth, so presumably 745 is equivalent to 1980 A.D.]

--DB Episode 61: Up on Karin Tower, Karin begins a five year fast.
[Ref: When first meeting Goku, Karin says he hasn’t eaten for five years. Apparently he’s fine going that long without food.]

May 7th, Age 745
--The 20th Tenkaichi Budokai is held. The champion and runner-up are both unknown, but by this time Akkuman (a devil from Hell) had won the tournament twice, while King Chapa had won at least once. The next tournament is held in five years, in Age 750, but afterwards the tournament’s growing popularity leads to it being held every three years.
[Ref: Date calculated from TB being held every 5 years during this period, and always on May 7th. Akkuman’s record is from Chapter 104, and Chapa’s is from Chapter 114. Kame-sennin explains the tournament’s changing schedule in Chapter 112.]

AGE 746
--DBZ Episode 16: Pigero is born.
[Ref: The head orphan from the episode. He’s 16 when he appears, according to his Daizenshuu 7 bio. I think this is said in the episode itself, but can’t be bothered to check.]

AGE 747
--Yamcha and Puar meet. They become partners in crime, robbing anyone who passes through the desert east of Mount Frypan.
[Ref: Date from Daizenshuu 7. This means Yamcha and Puar had known each other for 2 years when they first appear, and met when Yamcha was 14 and Puar was 7. I think this might be based on the fact that Puar graduated from the Shape-Shifting Kindergarten, and presumably he met Yamcha after that. I suppose 7 would be a reasonable age to graduate kindergarten.]

--Dr. Slump: To defeat Arale Norimaki and take over Earth, Senbe Norimaki’s rival Dr. Mashirito creates Caramel Man No.4. Based on the same design as Arale, Caramel Man No.4 is equally powerful. Unfortunately for Mashirito he is so similar to Arale that he falls in love with her. He changes his name to “Obotcha Man” and takes up residence in Penguin Village.
[Ref: The date for Obotcha Man’s creation is from his Daizenshuu 7 bio. The rest is a summary of Dr. Slump.]

AGE 748
--Kame-sennin’s pet “immortal” phoenix dies of food poisoning. Sometime later, Kame-sennin’s Sea Turtle goes out into the mountains to gather mushrooms and becomes lost.
[Ref: Date from Daizenshuu 7. In Chapter 3 Sea Turtle says he’s been lost for the past year after he went mushroom-gathering, so this is a year before he meets Goku. In Chapter 4 Sea Turtle knows of the phoenix’s death (while Kame-sennin had forgotten), so it probably happened before Sea Turtle got lost, but still fairly recently. For some reason online translations of Daizenshuu 7 timeline typically say Kame-sennin and Sea Turtle met this year; it’s another mistake that gets copied and pasted everywhere.]

--Due to the bullying he receives from the senior pupils, Kuririn is driven in tears from Oorin Temple. He begins heading for Kame-sennin’s island to train there instead.
[Ref: Kuririn getting bullied out of Oorin is mentioned in Chapter 34. In Chapter 28 he says he trained there for eight years, while Daizenshuu 7 says he began in 740. It’s possible Kuririn did other stuff between leaving Oorin Temple and heading for Kame-sennin’s, since it’s a year before he shows up at Kame House.]

AGE 749
--Dr. Slump: Sometime this year, Senbe and Midori’s son Turbo Norimaki is born in Penguin Village. Shortly after his birth, he is struck by a passing alien spaceship. The aliens use their advanced technology to revive him, but due to his young age this causes strange side-effects. Turbo develops super-genius intellect enabling him to talk and be a better inventor than his father while still just a baby. He also gains the ability to levitate and various other psychic powers.
[Ref: The date is from Turbo’s Daizenshuu 7 bio. The info is a summary of Dr. Slump.]

--DBZ Episode 16: Hatchi is born.
[Ref: An orphan from the episode. His Daizenshuu 7 bio says he’s 12 when he appears.]

Early April, Age 749
--Bulma enrolls in West City High School
[Ref: From Daizenshuu 7. Chapter 2 establishes that Bulma is 16 at the start of the series, an appropriate age for someone to begin high school (it’s the same age Gohan does in Chapter 421). In Japan the school year begins in April, so apparently it works the same in DB Earth. In Chapter 68 Bulma is shown attending school on Saturday, another feature of Japanese education (in Viz they change the day to Friday).]

Sometime between April and August, Age 749
--Bulma discovers the 2-Star Ball in her house’s basement. Wondering what it is, she asks various people about it, but no one knows. Eventually though she finds an ancient document that tells all about the Dragon Balls. Bulma notices that the Dragon Balls emit a unique electric-magnetic wave, so she creates a device capable of using that to calculate their precise location, which she dubs the “Dragon Radar”. Once her summer vacation starts, she sets out to find the remaining Dragon Balls and wish for a nice boyfriend.
[Ref: Bulma explains most of this in Chapter 1, while in Chapter 2 she says it’s her school vacation. Daizenshuu 7 dates this all to “some unknown month and day” but I’ve decided to adjust it to “between April and August” based on the dates for the prior and following entries.]

August 22nd, Age 749
--Bulma discovers the 5-Star Ball in North Valley.
[Ref: In Chapter 1 Bulma says she found the 5-Star Ball ten days ago (this line drops out in the Viz translation). So this is 10 days before September 1st, the date Bulma meets Goku.]

September 1st, Age 749 (#DRA)
Bulma and Son Goku meet
--Tracking the 4-Star Ball on her Dragon Radar, Bulma encounters Son Goku, who has been living on his own since Son Gohan’s death. Goku is unwilling to part with his memento of his grandfather, so he agrees to accompany Bulma on her search for the remaining balls. Bulma strategically doesn’t tell Goku that the Dragon Balls will scatter after a wish is granted.
[Ref: The date is from Daizenshuu 7. The month is given as September because after the search for the DBs wraps up, Goku trains for 8 months before entering the 21st Tenkaichi Budoukai. The Tenkaichi Budoukai is on May 7th, so eight months earlier would be in September of the previous year. So you end up with the DB search ending sometime around September 7th, and if you backtrack from there using the passages of time that are mentioned you can calculate the date that Goku and Bulma meet. Still, picking the date the DB search ends is a bit arbitrary, since presumably Goku didn’t train for exactly 8 months to the day. I wonder if they intentionally set things up so that the beginning of the story would also occur at the beginning of a month?]

DB Movie 1: Goku and Bulma battle King Gurumes’ army for possession of the Dragon Balls.
[Ref: The movie is an alternate version of the initial story arc, so I’m placing it here.]

September 2nd, Age 749
--In the morning, Goku and Bulma meet Kame-sennin’s pet Sea Turtle, who has been lost for the past year. They help reunite him with Kame-sennin, and in return Kame-sennin gives Bulma his 3-Star Ball, and Goku his Kinto-Un.
--DB Chapters 2-4 are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 2 shows Goku and Bulma camp for the night after they meet, and in Chapter 3 they get up in the morning and encounter Sea Turtle, so this is the next day after they meet.]

September 5th, Age 749
--Goku and Bulma find the 6-Star Ball in a village being terrorized by Oolong. They defeat Oolong and receive the ball as a reward. Bulma forces Oolong to accompany them, thinking his shape-shifting powers will come in handy.
--DB Chapters 4-6 are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 4 the narration says 3 days pass between Bulma and Goku’s meeting with Kame-sennin and their arrival in Oolong’s village.]

September 6th, Age 749
--While traveling to Mount Frypan, site of the next Dragon Ball, Goku and co. are attacked by Yamcha and Puar. Yamcha gives Goku a good fight, but due to his fear of girls he runs off when he sees Bulma. That night Yamcha attacks the group again and fails once more, though he does learn about the Dragon Balls.
--DB Chapters 7-9 are set on this day.
[Ref: Date from Daizenshuu 7. Near as I can tell nothing in the manga indicates how much time passes between them recruiting Oolong and meeting Yamcha.]

September 7th, Age 749
--In the morning Yamcha attacks a third time and is decidedly beaten by Goku. Changing tactics, he decides to follow after Bulma and co. as they gather the Dragon Balls, then steal all the balls at the last moment.
----DB Chapter 10 is set on this day.
[Ref: In Daizenshuu 7 the date for this is September 9th, but this is a mistake. In Chapters 7-9 Goku meets Yamcha, Yamcha attacks again that night, and then comes attacking once again on the next morning. So if Goku met Yamcha on the 6th, Goku should defeat him on the 7th, not the 9th. Presumably what happened is that this entry on Yamcha got mixed up with the September 9th entries during some point of the timeline-writing process, due to them being right next to each other.]

September 9th, Age 749
The Dragon Balls are assembled
--In the morning, Bulma and co. finally arrive at Mount Frypan, where they meet Gyumao and Chi-Chi. Goku and Chi-Chi track down Kame-sennin, who puts out Mount Frypan’s fire with his trademark Kamehameha technique, although he accidentally destroys the entire mountain and castle too. Still, Bulma discovers the 7-Star Ball in the rubble. Learning that Goku is Son Gohan’s grandson, Gyumao offers to give him Chi-Chi’s hand in marriage when the two are older. Goku agrees, but assumes “marriage” is a kind of food.
--In the afternoon, the group encounters the Rabbit Gang in Mushroom City. Using the Nyoibo, Goku carries the Carrotizer Bunny and the rest of the gang all the way to moon, where he leaves them.
--As the group approaches the final Dragon Ball, they are attacked by Pilaf’s henchmen Shu and Mai, who steal their Dragon Balls. The group gets trapped in Pilaf’s castle, and that night Pilaf assembles all seven Dragon Balls and summons Shen Long. He tries to wish for world domination, but Oolong manages to wish for panties first, and the Dragon Balls scatter. Goku and co. escape from Pilaf’s prison when Goku looks at the full moon and transforms into an Oozaru, smashing down the prison and Pilaf’s entire castle.
--DB Chapters 11-22 are set on this day.
[Ref: Daizenshuu 7. Chapter 11’s opening narration says 2 days pass between Yamcha’s defeat and the group reaching Frypan. From Frypan to Pilaf, the only night scene that’s shown is the one at the end, when Pilaf summons Shen Long, so it’s reasonable to say that this was all one day, although a busy one to be sure. Also, during the Pilaf stuff Bulma is still wearing the clothes she bought in the Rabbit Gang Town. Incidentally, Daizenshuu 7's timeline is the only place I know of that the Rabbit Gang's town is given a name: "Mushroom City".]

—DBO: A youth from Age 1000 is briefly carried to this era by a time rift, and encounters Gyumao and Chi-Chi.
[Ref: A description of one of the Time Leap Quests in the game.]

September 10th, Age 749 (#TRA)
Son Goku and Kuririn become Kame-sennin’s pupils
--With the Dragon Ball search over, Bulma returns to West City with Yamcha (her new boyfriend), while Goku decides to go train under Kame-sennin. Goku and Kuririn both arrive at Kame-sennin’s island about the same time, but Kame-sennin will only take them on as pupils if they bring him a hot gal to keep him company. The two find Lunch, who has just committed a robbery and is wanted by the police. Needing a place to hide out, she agrees to live with Kame-sennin, and Goku and Kuririn officially become his pupils.
--To start their training off, Kame-sennin has Goku and Kuririn search for a single stone in a forest. Kuririn wins by cheating, meaning he gets to eat dinner while Goku does not. However, dinner turns out to be puffer fish improperly cooked by Lunch…
--DB Chapters 23-29 are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 23 shows that it’s the next day after Goku’s rampage. From there nothing indicates a day passes until Chapter 29.]

—DB Movie 2: To become his pupils, Kame-sennin tasks Goku and Kuririn with bringing him the legendary Sleeping Princess of Devil’s Castle. At Devil’s Castle they defeat the demon Lucifer, who tries to use the Sleeping Princess (actually a jewel holding nearly limitless power) to destroy the sun and make the world more hospitable for demons.
[Ref: The movie’s an alternate version of Goku and Kuririn’s quest to become Kame-sennin’s pupils, so I’m putting it here. Bulma refers to herself as 16 years old in the movie]

September 11-13th, Age 749
--Kame-sennin, Kuririn, and Lunch are bedridden by food poisoning they got from the puffer fish they ate on the 10th, so training is postponed.
[Ref: From Chapter 29’s closing narration, which says everyone was sick for 3 days.]

September 14th, Age 749
--Goku and Kuririn’s training begins at 4:30 in the morning. They devote themselves to training for the next eight months, with the goal of entering the next Tenkaichi Budokai.
--DB Chapters 30-31 are set on this day.
[Ref: Date from Daizenshuu 7. As mentioned, this is 3 days after Chapter 29, while Chapter 30 depicts their early-morning training and says the tournament is in 8 months. Since the Dragon Balls are revived by that time this is a bit of a plot-hole, but maybe they regenerated earlier than normal because Oolong’s wish was so minor?]

September 15th, Age 749
--Goku and Kuririn undergo the same training as the day before, but now wear 20 kilo turtle shells. They continue training while wearing these weights for the next seven months.
[Ref: At the end of Chapter 31 Kame-sennin gives the boys the 20 kilo turtle shells, while in Chapter 32 he gives them higher weights a month before the TB.]

October 2nd, Age 749
--The second semester begins at West City High School, and Bulma returns to school.
[Ref: Date from Daizenshuu 7. In Chapter 2 Bulma says she has 30 days of vacation left. That was on September 1st, so this would be when school starts up again. In Japan, the spring semester is seen as the start of the academic year, which is why this fall semester is referred to as the second semester.]

AGE 750 (#750)
--During this year, Tao Pai-Pai celebrates his 20th anniversary as an assassin, slashing his prices in half.
[Ref: He mentions this in Chapter 85.]

--By this year, Capsule Corporation controls 40% of the world market in vehicles. Their chief rival is the Red Ribbon Army, which controls 16% of the market. Though the two’s production numbers are somewhat close, performance-wise Capsule Corporation vehicles are far superior.
[Ref: This is explained in Daizenshuu 7’s section on Capsule Corporation, pages 202-203.]

--Sometime this year, Adjunct Black obtains information on the Dragon Balls. Thinking that they could further the Red Ribbon’s goal of world domination, he informs Commander Red about them. Red however thinks the army can simply take over the world through its military strength alone, and instead decides to use the Dragon Balls to make himself taller, so that he will be a sufficiently cool-looking world ruler. Red decides to have his subordinates search for the Dragon Balls, though he doesn’t bother informing them of his exact desires.
[Ref: This is explained in Chapter 95. For the date, at the start of the RR arc Silver Platoon has been looking for its Dragon Ball 20 days, so I’m assuming the RR hasn’t been after them for too long. Not to mention it’s only been 8 months since the DBs were last used, which shouldn’t even be enough time for them to revive, but whatever.]

April 6th, Age 750
--Goku and Kuririn’s progress is far greater than Kame-sennin expected, so he increases the weight of their training shells to 40 kilos.
--DB Chapter 32 is partially set on this day.
[Ref: Date from Daizenshuu 7. Chapter 32 shows Kame-sennin giving them the higher weights.]

April 18th, Age 750
--The Red Ribbon Army’s Silver Platoon begins its hunt for the 6-Star Ball in the eastern region of the world.
[Ref: Date from Daizenshuu 7. In Chapter 55 one of Silver’s underlings says they’ve been searching for the Dragon Ball for 20 days, so this is that long before May 8th. The DB’s general location is from Daizenshuu 4’s Earth map.]

--Possibly around this same time, General White and his platoon begin looking for the 2-Star Ball in the northern region of Earth. Based in Muscle Tower, the Red Ribbon’s northern stronghold, he takes the mayor of nearby Jingle Village hostage and forces the villagers to help him look for the ball. Doctor Gero’s creation Android No.8 is brought to Muscle Tower as a secret weapon. While out walking one day, No.8 happens to discover the 2-Star Ball by chance. However, learning that General White plans on killing the villagers once he’s found the ball, No.8 keeps it hidden.
[Ref: Explained in Chapters 57 and 67. For the date I’m just guessing it’s around when Silver Platoon starts their search too.]

--Also possibly around this point, Yellow Platoon invades the Holy Land of Karin to get the Dragon Ball there. The platoon is held off by Bora and his son Upa, members of the family that has guarded the Holy Land and Karin Tower for generations.
[Ref: Reasoning behind the date is the same as above. The end of this long stand-off is in Chapter 84.]

Early May?
--A drought threatens Namu’s village. Learning that the Tenkaichi Budokai is soon, he resolves to win it and use the prize money to buy water for his village, to sustain them until the rainy season. He doesn’t realize that water is free for the taking in more prosperous regions.
[Ref: In Namu’s flashback in Chapter 38 he says the tournament is very soon. Kame-sennin explains Namu’s mistake in Chapter 46.]

May 6th (Wednesday), Age 750
--Their training complete, Goku and Kuririn set off for Papaya Island, site of the Tenkaichi Budokai. Kame-sennin goes with them, ostensibly to guide them there and watch their matches, but really to participate in the tournament himself disguised as “Jackie Chun”. Kame-sennin is afraid that one of them might actually win the tournament, which he thinks would make them become arrogant and slack off in their training.
--DB Chapter 32 is partially set on this day.
[Ref: Date from Daizenshuu 7. Chapter 32 identifies this as the day before the tournament. Kame-sennin’s motives for his disguise are explained in Chapter 46.]

May 7th (Thursday), Age 750 (#21T)
--The Red Ribbon Army’s Brown Squad finds the 7-Star Ball.
[Ref: In Chapter 55 Silver mentions that Brown Squad found a DB yesterday.]

The 21st Tenkaichi Budokai
--In Match 1 Kuririn defeats Bacterian, in Match 2 Jackie Chun defeats Yamcha, in Match 3 Namu beats Ran-Fan, and in Match 4 Goku defeats Giran. In the semi-finals, Jackie Chun defeats Kuririn, and Goku defeats Namu. During the finals, Jackie Chun blows up the moon to stop Oozaru Goku. After a long battle Jackie Chun is champion, and Goku is runner-up. That night, Goku borrows Bulma’s Dragon Radar and sets out to find the 4-Star Ball. As a result of Jackie Chun blowing up the moon, the Carrotizer Bunny is left floating in space, while Man-Wolf is left unable to transform.
--DB Chapters 32-54 are set on this day.
[Ref: Date from Daizenshuu 7. Carrotizer Bunny being left floating in space is from the Toriyama Q&A in Boken Special. Man-Wolf’s conundrum is from Chapter 119. It being Thursday comes from Bulma’s line in Chapter 68 about it being Sunday tomorrow (Saturday in Viz). That day was the 9th according to Daizenshuu 7, so backtracking this becomes Thursday. Apparently Bulma cut class to attend the tournament.]

--DB Episodes 29-33: Goku and Chi-Chi reunite at Gyumao’s village, built near the ruins of Mount Frypan. Soon Goku, Pilaf, and the Red Ribbon Army all fight over the 6-Star Ball. Ultimately it goes to the Red Ribbon Army, who get it after shooting down Pilaf’s secret base out in the desert. The Red Ribbon Army also obtains the 5-Star Ball.
[Ref: Daizenshuu 7 places the events of these filler episodes all on the same day as the tournament. I still haven’t watched these episodes, so I don’t know how accurate this is. This version of how Goku finds the 6-Star Ball and meets Silver differs considerably from the manga.]

—DB Movie 3: Goku and Kuririn enter a tournament in the Mifan Empire. They save the young Mifan emperor Chaozu from his scheming ministers, Tsuru-sennin and Tao Pai-Pai.
Ref: The movie’s an alternate version of the TB, and seems a direct sequel to DB Movie 2, so I’m putting it here. The movie takes place over at least two days: there's a night scene in the middle and they talk of the tournament as the next day.

May 8th (Friday), Age 750 (#RRA)
--Goku obtains the 6-Star Ball, and fights off the Red Ribbon Army’s Silver Platoon in the process. Still after his grampa’s 4-Star Ball, Goku travels north to Jingle Village and defeats General White, Sergeant Major Murasaki, and the other soldiers at Muscle Tower. In the process Goku meets Android No.8, who though powerful has a peaceful and gentle personality (clearly a failure from Doctor Gero’s perspective). No.8 befriends Goku, giving him the 2-Star Ball he had found earlier. Goku spends the night in Jingle Village, and discovers that the Dragon Radar is broken.
--DB Chapters 55-67 are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 54 Goku sets off from the TB grounds at night, and at the start of Chapter 55 it is morning, at which point he runs across Silver and co. It makes sense to assume this is the very next day, as Daizenshuu 7 does. Some people though try to fix the plot-hole about the DBs already being revived by saying that a long time passes, long enough for it to have been a full year since the balls were last used, but I personally don’t like this approach.]

May 9th (Saturday), Age 750
--Goku travels to West City and has Bulma fix the Dragon Radar. She finishes at 11:02 AM, and the two set out together to find the next Dragon Ball, which proves to be in the abandoned pirate caves near Kame-sennin’s island. While searching for this ball, Goku and co. get into a protracted series of battles against General Blue and his platoon. Ultimately Goku chases Blue to Penguin Village, where Arale Norimaki sends him flying across the globe. Goku next goes to the Holy Land of Karin, where he saves Upa from the Yellow Platoon and finally finds the 4-Star Ball. Fed up with his army’s repeated failures to handle Goku, Commander Red hires Tao Pai-Pai to kill him. Arriving in the Land of Karin, Tai Pai-Pai effortlessly kills Bora and defeats Goku, leaving him for dead. Reviving, Goku begins to climb Karin Tower to get the strength to defeat Tao Pai-Pai.
[Ref: Date from Daizenshuu 7, which also notes the time Bulma finishes repairing the radar. This comes from Chapter 69: on the first panel of the chapter’s 11th page, a clock reads “11:02”. In this chapter Bulma also notes that tomorrow is Sunday (Viz changes this to Saturday). Chapter 67 shows Goku spending the night at Jingle Village and setting off for West City the next day. From that point to Chapter 87 when Goku climbs Karin Tower, there’s no night shown, so it does all seems to be a single day.]

May 10th (Sunday), Age 750
--In the early morning, Goku reaches the top of Karin Tower. He begins training under Karin, by trying to grab the Super Holy Water away from him.
--Summer vacation begins at Penguin Village High School.
--DB Chapters 87-89 are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 87 shows Goku sleeping overnight midway along Karin Tower, and reaching the top the next morning. In Chapter 81 Akane says their summer vacation starts the next day.]

May 12th (Tuesday), Age 750 (#UBB)
The Red Ribbon Army is destroyed
--On his third day of training, Goku snatches the Super Holy Water from Karin. Goku wins his rematch against Tao Pai-Pai, who is gravely injured by his own bomb after Goku knocks it back at him. Leaving Tao Pai-Pai for dead, Goku goes on to attack Red Ribbon Army Headquarters and defeats the entire army on his own.

Goku reunites with Gohan
--To resurrect Bora, Goku searches for the final Dragon Ball. Unbeknownst to him, Pilaf is keeping it inside a special container that prevents it from showing up on the Dragon Radar. At a loss, Goku and co. see Uranai Baba to get her to divine its location. They defeat her five fighters, the last one of whom is Son Gohan, able to visit the living world for one day thanks to Uranai Baba’s powers. Pleased to see Goku’s growth, Gohan returns to the afterlife. After learning the final ball’s location from Uranai Baba, Goku quickly defeats Pilaf, summons Shen Long, and wishes that Bora be brought back to life. The instant the Dragon Balls scatter, Goku grabs the 4-Star Ball so that he won’t need to search for it again.
--His quest over, Goku decides to train for the next Tenkaichi Budokai in three years. Kame-sennin advises him to travel around the world on his own to grow even stronger, while Yamcha becomes Kame-sennin’s new pupil.
--DB Chapters 89-112 are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 89 shows Goku grabbing the Super Holy Water after 3 days. After that events follow one after the other until Chapter 112 when Goku sets off train for the tournament.]

Sometime in July, Age 750
--Namu’s village enters its rainy season.
[Ref: Date from Daizenshuu 7. In Namu’s flashback thingy in Chapter 38 Namu says the rainy season won’t be for another 2 months. That was probably in May (Namu says the tournament is very soon), so the rainy season would be now. In some of the online timeline translations, it incorrectly describes Namu’s village as being on Namek (?!).]

AGE 750 to AGE 753
--DB Episodes 79-82: Goku travels around the world to further his training. He defeats the bandits Kinkaku and Ginkaku, and fights the martial artist Tenlong on behalf of Chin Taiken. In the Kress Kingdom, Goku travels through the Demon Realm Gate and rescues Princess Mise from the Demon Realm martial artist Shura. In Mentanpin Village he meets Tsuru-sennin’s pupils Tenshinhan and Chaozu. The two use their master’s old pet Inoshikacho to swindle money from the villagers: first they have Inoshikacho rampage around, then they pretend to fight the monster off in exchange for money.
[Ref: Date from Daizenshuu 7. Chapter 112 establishes that Goku spends the three years until the next tournament traveling the world, but only the anime depicts his journey. Notably, this filler results in Goku meeting Tenshinhan and Chaozu earlier and under very different circumstances than in the manga.]

Roughly AGE 750~764
Doctor Gero’s android research continues
--Though the Red Ribbon Army was destroyed by Goku, its scientific advisor Doctor Gero survives. To get revenge on Goku for destroying the Red Ribbon’s dream of world domination, he begins developing more androids to defeat Goku. He has insectoid spy robots gather data on Goku during important fights, in order to analyze his strength and techniques and determine what sort of androids are needed to defeat him. Of the androids made after the Red Ribbon’s collapse, No.9-No.15 all have various problems (though No.13-No.15 are fairly close to perfected), and so Gero eventually disposes of them. No.16 also has problems, but Gero leaves him around, intending to fix him later.
--Sometime during this period, Gero also begins experimenting with bio-technology, conducting research into making an android from the combined cells of fighting masters. Ultimately though he determines that this research will take too long, and abandons the project midway through. Instead he entrusts the super computer located in his laboratory’s basement to continue the project. It works ceaselessly, and in time uses Gero’s insectoid spy robots to collect cells from powerful martial artists.
[Ref: Info from Gero’s explanation in Chapter 340, Gero’s comment on No.16 in Chapter 350, Chapter 367’s title page, and Cell’s explanation in Chapter 363. For the year range, the starting year is the destruction of the RR while the end year is somewhat arbitrarily the year Trunks warns Goku. I’ll explain about this later.]

AGE 750~756
--After being left seriously injured in his fight with Goku, Tao Pai-Pai spends all the money he had saved over his career as an assassin to rebuild himself into a cyborg. Sometime after May of Age 753 he reunites with his brother Tsuru-sennin, and they beginning plotting revenge.
[Ref: Simply the years between his first and second appearances.]

AGE 751
--DBZ Episode 16: Yordon is born.
[Ref: One of the orphans from the episode. Daizenshuu 7 gives his age when he appears as 11.]

AGE 753
--By this year, Ran-Fan has married a man named “Trunks” and become a housewife.
[Ref: This is mentioned in her Boken Special profile. The name of her husband comes from Ran-Fan’s own connection to underwear (her name’s a pun on “lingerie and foundation”), and predates the creation of Bulma and Vegeta’s son by several years.]

April~May?, Age 753
The revival of Piccolo Daimao
--Sometime during this year, Pilaf retrieves the electric rice cooker containing Piccolo Daimao from the ocean floor. He releases Piccolo from his seal, hoping that Piccolo will then help him take over the world out of gratitude. He tells Piccolo of the Dragon Balls, but rather than use those to wish for world domination, Piccolo wants to wish to have his youth restored. Taking over the world will be easy after that. Piccolo gives birth to new Demon Clansmen, “Piano” and “Tambourine”. Piano assists the elderly Piccolo, while Tambourine is in charge of tracking down and killing all powerful martial artists in the world, who Piccolo fears may use the Mafuba to seal him away again. To further this goal, Pilaf tells Piccolo of the Tenkaichi Budokai, whose tournament registry should list the best current martial artists.
[Ref: These events are explained in Chapter 135. For the date I’m just assuming Piccolo hasn’t been released too long before he first appears. Daizenshuu 7’s bios for Piano and Tambourine say they were born In 753.]

--DBO: Besides Piano and Tambourine, Piccolo gives birth to several more monsters at this point. Pilaf stores them in his castle and raises them in secret, but over the next few centuries they somehow get loose and multiply in the wild.
[Ref: These extra monsters are mentioned in the DBO timeline. Since they’re said to have originally been stored in Pilaf’s castle, I’m assuming Piccolo birthed them this year rather than back during his initial rampage.]

May 7th, Age 753 (#22T) (#PIC)
The 22nd Tenkaichi Budokai
--Tsuru-sennin enters his pupils Tenshinhan and Chaozu in the tournament. King Chapa also attends, but is defeated by Goku in the preliminaries. For the main tournament, in Match 1 Tenshinhan defeats Yamcha, in Match 2 Jackie Chun defeats Man-Wolf, in Match 3 Kuririn defeats Chaozu, and in Match 4 Goku defeats Panput. In the semi-finals, Tenshinhan defeats Jackie Chun, and Goku defeats Kuririn. Winning by a narrow margin, Tenshinhan is champion, and Goku is runner-up. Over the course of the tournament, Tenshinhan is influenced by Jackie Chun (Kame-sennin) and leaves the Crane School. Chaozu follows suit. At the same time, Doctor Gero’s insectoid spy-robot covertly gathers battle data on Goku and the other tournament fighters.

Piccolo's plan goes into operation
--After the tournament, Kuririn is killed by Tambourine when the demon steals Goku’s 4-Star Ball and the tournament registry. Goku goes after Tambourine, but is too exhausted from the finals to put up a fight. Tambourine destroys Goku’s Kinto-Un and defeats Goku. That night, at the tournament grounds Tenshinhan and co. head to Kame-sennin’s house to plan their next move.
--DB Chapters 113-136 are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 152 establishes that Piccolo Daimao addresses the world on May 9th, so backtracking gets you this date. In the manga the tournament is one day, but in the anime it is several. Chapter 136 shows nightfall and the next morning. In Chapter 340 Gero says he spied on Goku and co. “at the tournament, and at the battles with Piccolo and Vegeta”. Which tournament isn’t specified in the manga, but the fact that it’s mentioned before and separately from the battle with Piccolo implies it’s the 22nd, and the anime flat-out shows Gero spying on the 22nd TB too, so I’m going with that.]

The anime version of the tournament (DB Episodes 83-101):

May 1st, Age 753
--Goku meets the fox thief Konkichi, and sets out for the Tenkaichi Budokai grounds on Papaya Island.

May 3rd, Age 753
--Registration is held for the 22nd Tenkaichi Budokai.

May 4th, Age 753
--The 22nd Tenkaichi Budokai preliminaries are held. In Match 1 of the main tournament, Tenshinhhan defeats Yamcha.

May 5th, Age 753
--The second day of the 22nd Tenkaichi Budokai. In Match 2 Jackie Chun defeats Man-Wolf, and in Match 3 Kuririn defeats Chaozu.

May 6th, Age 753
--The third day of the 22nd Tenkaichi Budokai. In Match 4, Goku defeats Panput. For the semi-finals, Tenshinhan defeats Jackie Chun, while in the evening Goku defeats Kuririn.

May 7th, Age 753
--The fourth day of the 22nd Tenkaichi Budokai. In the finals, Tenshinhan narrowly defeats Son Goku. After the tournament, Kuririn is killed by Tambourine when the demon steals Goku’s 4-Star Ball and the tournament registry. Goku goes after Tambourine, but is too exhausted from the finals to put up a fight. Tambourine destroys Goku’s Kinto-Un and defeats Goku. That night, at the tournament grounds Tenshinhan and co. head to Kame-sennin’s house to plan their next move.
[Ref: The anime shows the tournament taking place over many days, as outlined above. For the dates, I’ve used May 7th (the date of the entire tournament in the manga) and backtracked from there, in order not to mess up Piccolo’s speech being on May 9th, which is stated in the manga and anime. Daizenshuu 7 (which counts the tournament as one day) dates Goku meeting Konkichi to May 5th, two days before the tournament. I’ve moved it to two days before tournament registration in this set-up.]

May 8th, Age 753
--DB Episode 113: At King Castle, Mister Dog holds a memorial ceremony celebrating the 20th year of his reign over Earth.
[Ref: Date from Daizenshuu 7. As shown in the episode. OK, so I totally made the name “Mister Dog” up, but other than that it’s exactly like in the episode.]

Piccolo Daimao regains his youth
--Recovering from his defeat, Goku meets Yajirobe. Piccolo gives birth to a new demon, Cymbal, and has him collect Dragon Balls, while Tambourine kills various martial artists (including Namu and Giran). Since Yajirobe has the 1-Star Ball, Cymbal soon tracks him down, but Yajirobe kills and eats him. Piccolo next sends Tambourine, who Goku easily kills now that he’s fully rested. Piccolo himself finally attacks, effortlessly pummeling Goku and leaving him for dead. At Goku’s request, Yajirobe takes Goku to Karin Tower.
--Kame-sennin, Tenshinhan, and the others try gathering the Dragon Balls so they can wish to Shen Long to destroy Piccolo. Since Piccolo himself is collecting the balls, they finally come into conflict. Kame-sennin uses the Mafuba to try and seal Piccolo away just as Mutaito had done, but he messes the technique up, dying from the strain without accomplishing anything. Piccolo summons Shen Long and wishes to be young again, destroying Shen Long once his wish is granted. Chaozu tries to interfere, but is killed. The sole survivor, Tenshinhan begins practicing the Mafuba to successfully seal Piccolo away.
--Piccolo attacks King Castle, overthrowing Mister Dog and becoming the new King of Earth. Meanwhile, Yajirobe begins climbing Karin Tower with Goku on his back. That night they reach the top. To gain the power to defeat Piccolo, Goku drinks the Super God Water around midnight and spends the next six hours in agony. Meanwhile, Tenshinhan practices and masters the Mafuba.
--DB Chapters 136-151 are set on this day.
[Ref: Date from Daizenshuu 7. Events follow one after the other until Chapter 151, which shows Goku suffering through the night and recovering in the morning. When Piccolo attacks King Castle, those scenes are day while the scenes of Goku and Yajirobe and Karin Tower are at night. Apparently this is to show the distance between those two parts of the world; it’s already night at Karin Tower but not at King Castle. Chapter 151 says Goku suffers for 6 hours. When he starts it’s night, and when he finishes it is day, so he must have started around midnight.]

May 9th, Age 753
Piccolo Daimao is defeated
--In the morning Goku overcomes the effects of the Super God Water. Powered up, he receives a new Kinto-Un from Karin and sets off to defeat Piccolo. Tenshinhan confronts Piccolo first, but his attempt to use the Mafuba doesn’t pan out. Instead he is easily beaten by Piccolo’s latest demon spawn, Drum. Goku arrives and kills Drum in the nick of time. He and Piccolo begin a battle that destroys much of Central City, but in the end Goku wins. Dying, Piccolo gives birth to a new demon, half reincarnation and half son, who he entrusts with destroying Goku. This fight is observed by Doctor Gero’s insectoid spy robot.
[Ref: The day of the month is said in Chapter 153 and is one of only a few such dates given throughout the series. The year number is from Daizenshuu 7. Ma Junior is referred to interchangeably as the first Piccolo’s reincarnation or son. It seems to be a mixture of both. His “reincarnation” status presumably explains why God didn’t die when the first Piccolo did. In Chapter 340 Gero says he spied on Goku’s battle with Piccolo. He doesn’t say which one, but I’m assuming both.]

Goku becomes God’s pupil
--To revive Shen Long, Goku uses the Nyoibo to travel to God’s temple. God and Mister Popo rebuild Shen Long, and have him immediately restore to life all those killed by Piccolo and his demons. God knows that Piccolo’s reincarnation will attempt to ambush Goku at the next Tenkaichi Budokai in three years. He has Goku stay at his temple and train until then to defeat Piccolo.
--DB Chapters 151-165 are set on this day.
[Ref: Chapter 165 establishes that the next tournament is in three years.]

May~December?, Age 753
--DB Episodes 127-130: During his training in God’s temple, Goku tries to steal the holy crown of the Goro-Goro Mountains, learns to calm his mind via fishing, travels back in time and meets Mutaito, and fights a copy of himself created by Mister Popo.
[Ref: The opening narration for each of these episodes refers to the next tournament as 3 years away, so it can’t be too long after Daimao’s defeat.]

Late AGE 753 to AGE 756
--The God of Earth restores the planet’s moon. For safety reasons, he also permanently removes Goku’s tail so that he can never become an Oozaru again.
[Ref: Goku mentions God removing his tail in Chapter 167. This and the following entries are events established as occurring between Piccolo Daimao’s defeat and the 23rd TB, hence the year range.]

--Tenshinhan, Yamcha, Kuririn, and Chaozu climb Karin Tower. After training under Karin, they split up and train on their own for the remaining time before the 23rd Tenkaichi Budokai.
[Ref: Yamcha explains this in Chapter 169.]

--At God’s palace, Goku trains in the Room of Spirit and Time, where time flows differently: a year in the room is just a single day outside. However, the conditions inside are too tough for Goku, and he gives up after less than a month (ie less than 2 hours outside the room).
[Ref: Goku’s first attempt in the ROSAT is mentioned in Chapter 366. In Chapter 377 Goku says he was a kid when he first tried in the room, so I’m assuming it was relatively early during his training for the 23rd TB.]

[Herms]

AGE 754
--Dr. Slump: In Penguin Village, Akane Kimidori and Tsuku-tsun Tsun are married.
[Ref: Two chapters near the end of Dr. Slump shows Penguin Village ten years in the future, and by that time Akane and Tsuku-tsun are married. Tsuku-tsun’s Daizenshuu 7 bio says they get married when he’s 22, so going by his birth year (Age 732) that gives you this date.]

--DBZ Episode 16: Jink is born.
[Ref: Another orphan from that episode. His Daizenshuu 7 bio describes him as 7 when he appears.]

AGE 756
--Mark’s daughter Videl is born. Her mother dies at some unknown point in the next 17 years. Videl’s future classmates Sharpner and Erasa are also born this year.
[Ref: Date from Videl, Sharpner, and Erasa’s Daizenshuu 7 bio. This is a year before Gohan’s birth. Presumably the year Gohan spends in the Room of Spirit and Time puts him in the same class as them. However, SEG: Character Volume gives Videl’s birth year as 757, the same as Gohan’s. Videl’s mother’s death is mentioned in Chapter 429.]

May 7th, Age 756 (#23T)
The 23rd Tenkaichi Budokai
--The God of Earth inhabits the body of an ordinary man and enters the tournament as “Shen”, while the reincarnated Piccolo enters as “Ma Junior”. Tsuru-sennin and Tao Pai-Pai (now a cyborg) come to get revenge on Goku and co. Chi-Chi enters the tournament anonymously to reunite with Goku. In the preliminaries Goku defeats King Chapa again, while Chaozu loses to Tao Pai-Pai, and Yajirobe loses to Shen. For the main tournament, in Match 1 Tenshinhan defeats Tao Pai-Pai, in Match 2 Goku defeats Chi-Chi, in Match 3 Ma Junior defeats Kuririn, and in Match 4 Shen defeats Yamcha. In the semi-finals, Goku defeats Tenshinhan and Ma Junior defeats Shen. After a battle that levels the tournament grounds and much of Papaya Island, Goku is champion and Ma Junior runner-up. During the tournament, Goku gets engaged to Chi-Chi in the middle of their match. Doctor Gero’s insectoid spy robot monitors the tournament unobserved. As a result of Ma Junior destroying the tournament grounds, the Tenkaichi Budokai is not held again until Age 767.
--DB Chapters 166-194 are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 165 says this tournament is three years after the first Piccolo’s defeat, and Daizenshuu 4 says the tournament is always on May 7th. Daizenshuu 7 describes Goku as being 18 years old, when he turns 19 in 756. More support for the idea that Goku's birthday is sometime after May 7th. The idea that the destruction Piccolo causes explains the long gap until the 24th TB is from the anime. In Chapter 340 Gero says he spied on Goku during the Tenkaichi Budokai and his battle with Piccolo, both of which could refer to this.]

--DBO: A youth from Age 1000 is briefly carried to this era by a time rift, and visits the Tenkaichi Budokai grounds.
[Ref: A description of one of the Time Leap Quests in the game.]

--DB Episode 149-150: Goku and Chi-Chi return to Gyumao’s new castle at Mount Frypan to hold their wedding ceremony. During this time, Gyumao’s castle is engulfed by flames from the Furnace of Eight Trigrams, and the two of them set out to find the legendary Basho-Sen fan in order to put out the flames. Their quest takes them to Mount Kiwi, where they encounter the surviving Fire-Eating Bird and its chick.
[Ref: Date for Gyumao’s castle is from Daizenshuu 7. Octagon Village is the same episode, and I’m assuming the Mount Kiwi episode is on the same date. In the later episode, the tournament is said to have “just ended”, and Kame-sennin hasn’t returned home yet (we see him on a plane flying home). He’s home by the end of the episode.]

May 8th, Age 756
--DB Episodes 151-153: While continuing their search, Chi-Chi is trained by Grandma Hakkake in how to be a good wife. Goku and Chi-Chi finally obtain the Basho-Sen, but learn that it can’t extinguish the flames of the Furnace of Eight Trigrams. They head off to the Mountain of Five Elements, site of the furnace. There Goku reunites with his grandpa Son Gohan, and successfully fixes the furnace so that its flames no longer spew out to Mount Frypan. With that done, Goku and Chi-Chi have a formal marriage ceremony.
[Ref: Date for the Grandma Hakkake/furnace stuff from Daizenshuu 7. I’m assuming their marriage is on the same day.]

Sometime after May, Age 756?
--Lunch leaves Kame House to chase after Tenshinhan. But because Tenshinhan and Chaozu move around from region to region as they train, she isn't able to track them down.
[Ref: In Chapter 196 Kuririn says she left 5 years ago. The explanation of why Lunch couldn't find Tenshinhan is from Toriyama's "character secrets" page in Daizenshuu 7, page 122.]

AGE 757
May, Age 757
--Son Goku and Chi-Chi’s first son is born. Goku names him “Son Gohan”, after his adoptive grandfather. As a Saiyan/Earthling hybrid, Gohan has a tail and is gifted with vast dormant power.
[Ref: Date from Daizenshuu 7. In Chapter 196 Gohan says he’s 4, so this is that long before 761. Placing his birthday in May could refer to DBZ Episode 171, where Gohan celebrates his birthday before the Cell Games, which are in May. In that episode Gohan actually says it’s not his birthday: Chi-Chi just wants to celebrate it because Gohan got a year older in the Room of Spirit and Time, turning 11 (though this still wouldn’t rule out his birthday being during some other time in May). It may also be based on the fact that at the start of the Boo arc, the narrator says that Gohan is 16, though since the Boo arc is in 774 (13 years after Raditz’s arrival), Gohan should turn 17 that year. So him still being 16 would mean that his birthday is later in the year then when he first goes to Orange Star High School, which is in April. In Chapter 204 Vegeta notes how mixing Saiyan and Earthling blood creates a powerful hybrid, and Daizenshuu 4 somewhat expands on this by saying the two races’ genes have an “extraordinarily good compatibility”.]

AGE 759~760
--Goku is interviewed by Weekly Shonen Jump.
[Ref: The most mysterious entry in the Daizenshuu 7 timeline. My best guess is that at some point while the Saiyan story arc was running in Jump, there was a feature where Goku was “interviewed”. Such a thing was done with the Yu Yu Hakusho characters to mark that series’ 150th chapter, for instance. Then for the timeline, they stuck the interview sometime prior to Raditz’s arrival, perhaps because the interview didn’t portray Goku as mid-battle/dead/hospitalized.]

AGE 759
--Idasa is born.
[Ref: From his Daizenshuu 7 bio. He’s said to be 15 in Chapter 432.]

--Dr. Slump: By this time in Penguin Village, Taro Soramame and Tsuru-rin Tsun have married, while Senbe and Midori Norimaki have a daughter and a second son. Arale and Obotcha Man are married, and Senbe creates a robot baby for them. Meanwhile Akira Toriyama is homeless and destitute, his works forgotten.
[Ref: Shown in two chapters towards the end of Dr. Slump that depict Penguin Village 10 years in the future. These chapters are after Turbo Norimaki is born, so since Daizenshuu 7 places that in Age 749, these things should occur by 759.]

--DBZ Episode 16: A tsunami devastates Pigero’s town. Pigero, Hatchi, Yordon, Jink, and various other children lose their parents in the disaster, and take up living together in a ruined building.
[Ref: The episode says this was 2 years ago.]

AGE 760~770 (#760)
--DBGT: Doctor Mu restructures the alien Rild into a Machine Mutant, and makes him a general in the Machine Mutant Army. At the same time Mu completes work on M-2, a planet-sized Machine Mutant whose functions Mu links to Rild. Using Planet M-2 as a base, the Machine Mutant Army begins gathering energy from throughout the universe to further Baby’s development.
[Ref: Date and info from GT Perfect File Vol.1]

AGE 760
--Idasa’s younger brother Ikose is born.
[Ref: From his Daizenshuu 7 bio. He’s said to be 14 in Chapter 433.]

Sometime in Age 760?
--Out in space, Vegeta, Nappa, and Raditz discover a planet they can sell at a high price, but the job seems slightly difficult even for the three of them. Raditz remembers Kakarot, and heads off to Earth on his own to recruit him.
[Ref: Raditz explains this to Goku in Chapter 197. For the dating, I’m assuming that since it takes Vegeta and Nappa a year to reach Earth, then the same was probably true for Raditz. It’s possible though that the planet Vegeta and Nappa leave for Earth from isn’t the same place Raditz left from.]

AGE 761

—DBZ Movie 1: Garlic Junior attempts to get revenge on the God of Earth, using the Dragon Balls to gain immortality. His Demon Clan henchmen kidnap Son Gohan, whose hat has the 4-Star Ball on top, and Goku goes to rescue his son. In the resulting battle, Garlic Junior creates a “Dead Zone”, a type of black hole that sucks up everything in its surroundings and locks them away in a world of darkness. However, Garlic Junior is hit by Gohan’s powerful attack and knocked into the Dead Zone himself.
[Ref: Date from Daizenshuu 7. The description of the Dead Zone is from Daizenshuu 6’s section on the movie.]

November 28th, Age 761 (#SAI)
Raditz arrives on Earth
--He takes Gohan hostage to get Goku to join him and the other Saiyans in conquering planets. Goku and Piccolo team up and defeat Raditz, but Goku dies too. Learning of the Dragon Balls, Vegeta and Nappa depart for Earth to wish for eternal life. To protect Earth, Piccolo begins training Gohan by leaving him to fend for himself in the wilderness, while in the afterlife Goku heads for the North Kaio’s planet along the Serpent Road. During the night, Gohan becomes an Oozaru after seeing the full moon, and Piccolo destroys the moon to stop him.
--DB Chapters 195-208 (DBZ 1-14) are set on this day.
[Ref: Chapter 195 establishes this as 5 years since the 23rd TB. Chapter 204 says the Saiyans will arrive in 1 year. However, Chapter 209 says Goku takes 6 months to reach Kaio’s while in Chapter 211 Kaio says the Saiyans will arrive in 158 days, putting the exact figure at about 11 months, 8 days. In keeping with that, in Chapter 212 Kame-sennin and Piccolo note that the Saiyans are arriving a month sooner than expected. Daizenshuu 7 dates Raditz’s arrival as October 12th and sets Vegeta and Nappa’s arrival as November 3rd, roughly 13 months instead of 11. Possibly these dates were intended to go the other way around, since that would give about 11 months, then they accidentally got switched at some point. Still, I felt it easier to just change Raditz’s arrival date to be consistent with Vegeta and Nappa arriving Nov 3rd, rather than switch the two dates and have to change all subsequent Saiyan/Namek/Freeza arc dates accordingly.]

–DBO: The Time Breakers, led by the Masked Man, come from the future to interfere with history and gain Goku’s DNA. They brainwash Oozaru Gohan, but are stopped by the Time Patrol.
[Ref: An overview of three of the Time Machine Quests in the game.]

November 29th, Age 761
--Chi-Chi and Gyumao visit Kame House and learn what has happened to Goku and Gohan. Yajirobe also arrives, and begins rounding up Kuririn, Yamcha, Tenshinhan, and Chaozu so they can all train together at God’s temple.
--DB Chapter 209 (DBZ 15) is partially set on this day.
[Ref: Chapter 208 shows the night following the Raditz battle and the start of Gohan’s training, and Chapter 209 shows the next morning. This and the following dates for the Saiyan arc training are based on my date of Nov 28th for Raditz’s arrival.]

--DBZ Episode 9: Gohan falls into the ruins of Nemuria, and meets the All-Purpose Capsule Robot Model C-6 that was trapped there 80 years ago. When the ruins cave in, the robot helps Gohan escape to safety, but is destroyed in the process.
[Ref: The episode shows Gohan discovering the new clothes Piccolo gave him and that he now has no tail, so it must be the day after Gohan’s Oozaru rampage. Daizenshuu 7 dates it only as “Some month and day.”]

December, Age 761
--DBZ Episodes 10-11: Still in the wilderness, Gohan befriends a dinosaur who is killed shortly thereafter. Kuririn tracks down Yamcha, who is working as a baseball player. In space, Vegeta and Nappa stop on the insect world of Arlia. They kill the local dictator Moai, but decide the planet has no resale value and destroy it. They re-enter cold sleep and continue on their way to Earth.
[Ref: The opening narration for Episode 10 says it is 11 months before the Saiyans arrive. I assume this is going off of the initial statement of the Saiyans arriving in a year, rather than the later statement about them arriving a month earlier than that. So this episode is a month after the previous one. Episode 11 shows Yamcha and co. seemingly right after the events of the last episode, so I’m guessing not much time passes.]

AGE 762
--By this year, Namek’s population was still only 110. 86% were of the Dragon Clan, while 14% were Warrior-type Namekians.
[Ref: A pie-chart showing the proportion of Namekian types is featured in Daizenshuu 7’s race section and dated to this year. The planet’s population is from Daizenshuu 4’s section on Namekians, although to work this out you have to manually add up all the populations of the villages, plus Nail and the Great Elder. In Chapter 243 Kaio says there are a little over 100 Namekians, and in Chapter 260 Dende says he’s the Great Elder’s 108th child. The whole “re-population” thing would probably go quicker if the Great Elder allowed other people to have kids, but for whatever reason everyone on present-day Namek is his direct offspring, as Dende explains in Chapter 260.]

February, Age 762
--DBZ Episodes 12-13: Kuririn tracks down Tenshinhan and Chaozu, and they head for God’s temple via Karin Tower. Lunch chases after Tenshinhan and reaches the Karin Holy Land. In the afterlife, Goku has traveled a quarter of the way along the Serpent Road, but falls into Hell. He escapes, but finds himself back at the start of the road. Fortunately, while in Hell Goku ate some of Enma Daio’s special fruit, raising his speed and allowing him to make faster progress.
[Ref: The opening narration for Episode 12 says the Saiyans will arrive in 9 months, so another month has passed since last episode. Episode 13 follows on directly from Episode 12.]

March, Age 762
--DBZ Episode 14: Goku reaches the Serpent Road’s halfway point and meets the Serpent Princess. On Earth, Tenshinhan, Yamcha, Kuririn, Chaozu, and Yajirobe have finally all assembled at God’s temple and begin training to fight the Saiyans.
[Ref: The opening narration says the Saiyans will arrive in 8 months, so this is a month after the last episode. In the manga in Chapter 209 the narrator says Tenshinhan and co. were “quickly found”, but the anime has this take a total of 4 months.]

May 28th, Age 762
--DBZ Episodes 17-18: Tenshinhan, Yamcha, Kuririn, and Chaozu travel into the past and fight a pair of Saiyans in a war-torn Saiyan city. They are all killed, but since the trip was only in their minds they return safely to the present. Kame-sennin and Bulma have finished collecting the Dragon Balls so they can wish Goku back to life. An artificial full moon projected by Goku’s old spaceship turns Gohan into an Oozaru, but Piccolo stops the projection.
[Ref: Daizenshuu 7 dates Tenshinhan and co.’s time trip to sometime in May. Episode 17 says Tenshinhan and co. have been at God’s temple 2 months, making this that long since Episode 14. Episode 18 seems to follow directly after, and at the end Goku reaches Kaio’s, so this is the day before that. The anime shows Piccolo starting to train Gohan somewhat earlier than when Goku reaches Kaio’s, while in the anime they’re about the same time.]

May 29th, Age 762
--Goku finally crosses the Serpent Road and arrives at the North Kaio’s planet. To get used to the planet’s high gravity, he begins trying to catch Kaio’s pet monkey Bubbles. Around the same time, now that Gohan has managed to survive in the wilderness on his own for 6 months, Piccolo begins training him personally.
--DB Chapters 209-211 (DBZ 15-17) are set on this day.
[Ref: Chapter 209 says 6 months have passed since Goku started on the road, and since Gohan was left in the wilderness. Piccolo says the Saiyans are coming in 6 months, but Chapter 211 Kaio says they’ll arrive in 158 days. The date here comes from backtracking 158 days from Nov 3rd, the Daizenshuu 7 date for Vegeta and Nappa’s arrival.]

July 8th, Age 762
--Goku becomes used to the gravity on Kaio’s planet and catches Bubbles. He begins learning the Kaio-Ken and Genki-Dama from Kaio. Around the same time, Tenshinhan and co.’s training under God wraps up, and they begin training on their own down on Earth.
--DB Chapter 211 (DBZ 17) is partially set on this day.
[Ref: From Chapter 211. Goku catches Bubbles after 40 days according to the narrator, and Kaio says 118 days remain. This is 118 days before Nov 3rd.]

The anime version of Goku's training:

June 18th, Age 762
--DBZ Episode 19-20: Goku catches Bubbles. After that, his next training task is to hit Kaio’s attendant, the extremely fast cricket Gregory, with a heavy hammer.
[Ref: Episode 19 says Goku catches Bubbles after 3 weeks, in contrast to the manga where it takes 40 days.]

July 8th, Age 762
--DBZ Episode 20: Goku successfully hits Gregory with the hammer. He begins learning the Kaio-Ken and Genki-Dama from Kaio. Around the same time, Tenshinhan and co.’s training under God wraps up, and they begin training on their own down on Earth.
[Ref: After Goku hits Gregory, Kaio says 118 days remain. Essentially, the anime splits up the 40-day period in the manga where Goku catches Bubbles up between Goku catching Bubbles and hitting Gregory. This is 118 days before Nov 3rd.]

November, Age 762
--By this month, the Ginyu Special-Squad has invaded the planet Yardrat. The people of Yardrat are not strong, but use numerous unusual techniques, including a Teleportation technique that allows them to warp instantly to a person by locking on to that person’s ki.
[Ref: In Chapter 336 Vegeta knows of the squad’s invasion of Yardrat, so presumably the latest they could have started was November, since that’s when Vegeta departs Planet Freeza No.79, which is probably the last point he could have learned what the squad was up to.]

November 2nd, Age 762
--Goku completes his training, and is restored to life via the Dragon Balls. He begins rushing back across the Serpent Road to return to Earth in time to fight Vegeta and Nappa.
--DB Chapter 212 (DBZ 18) is partially set on this day.
[Ref: In Chapter 212 Kaio says the Saiyans will arrive the next day. He says Goku should cross the Serpent Road in 2 days, but for whatever reason Goku makes it by the next day. Presumably Kaio underestimated his speed. According to Kame-sennin, they weren’t expecting the Saiyans for over another month, which fits them arriving after only about 11 months and 8 days, rather than a full year.]

November 3rd, Age 762
Vegeta and Nappa arrive on Earth at 11:43 AM
--In the resulting battle, Yamcha is killed by one of the pair’s Saibai Men, while Chaozu, Tenshinhan, and Piccolo all die fighting Nappa. Piccolo’s death causes God to die too, and the Earth’s Dragon Balls turn to stone. Goku finally arrives and defeats Nappa, who Vegeta kills. Vegeta is defeated through the combined efforts of Goku, Gohan, Kuririn, and Yajirobe, but Goku spares his life, and he escapes into space. Kuririn suggests they travel to Planet Namek and use the Dragon Balls there to revive those killed by the Saiyans.
--DB Chapters 212-243 (DBZ 17-49) are set on this day.
[Ref: Date from Daizenshuu 7, time of day from Chapter 212. Chapter 241 shows night falling.]

Cell’s development begins
--During this battle, one of Gero’s insectoid spy robot harvests cells from Goku, Piccolo, and Vegeta. After collecting data from this battle, Doctor Gero concludes that he now completely grasps Goku’s strength and techniques. He ceases spying on Goku and devotes himself towards developing more androids. Meanwhile, Gero’s computer begins combining the cells it collected from Goku, Piccolo, Vegeta, and various other life-forms into a bio-technological android known as “Cell”. This process will take the next 24 years to complete.
[Ref: Cell explains about the cell-harvesting in Chapter 363, while Gero explains how he stopped spying on Goku in Chapter 340. It’s unclear whether the spy robot Cell talks about was the same one Gero was using, since according to Cell by this point Gero had entrusted Cell’s development to his computer. Details on Cell are from his life story in Chapter 363 and Chapter 367’s title page. In Chapter 363 Cell says his development won’t finish for 24 years, though this leads to several problems too complicated to go into here. Accordingly Daizenshuu 7 dates the start of Cell’s development to Age 762 (after Goku/Vegeta/Piccolo’s cells are harvested) and his completion to Age 786, meaning the 24 years Cell referred to had technically already started.]

--DBO: The Time Patrol again stops the Time Breakers from altering history, but is then attacked by the Masked Man and his master Miira. In the ensuing battle the Masked Man is revealed to be Bardock, who Miira rescued from Planet Vegeta’s destruction and brainwashed to be his servant. Bardock comes to his senses and seems to sacrifice himself to destroy Miira. The Time Patrol returns to the future, but in fact Miira and Bardock have both survived.
[Ref: A description of two of the Time Machine Quests in the game.]

November 4th, Age 762 (#FRE)
--Goku, Gohan, and Kuririn are hospitalized in West City Hospital. Mister Popo guides Bulma to God’s old spaceship on Yunzabit Highlands. The ship is brought to Capsule Corporation to be remodeled so that they can go to Namek.
--DB Chapters 243-245 (DBZ 49-51) are set on this day.
[Ref: Date from Daizenshuu 7. The narration in Chapter 243 says this is “the next day” after the battle with Vegeta wraps up.]

November 7th, Age 762
--Gohan and Kuririn’s hospital treatment ends.
[Ref: Date from Daizenshuu 7. In Chapter 243 Kuririn says it will be 3 days, so this is that long since the 4th.]

--DBZ Episode 40: About this time, a spaceship full of orphans from one of the planets attacked by Freeza’s forces passes by Planet Namek.
[Ref: In the episode the orphans say they passed Namek 2 weeks ago.]

November 9th, Age 762
--The remodeling of God’s spaceship is completed.
[Ref: Date from Daizenshuu 7. In Chapter 245 Bulma says God’s ship can be remodeled in 5 days, so this is that long since the 4th.]

November 14th, Age 762
--Capsule Corporation finishes converting the language system in God’s spaceship from Namekian to English. Bulma, Kuririn, and Gohan set out for Planet Namek.
--DB Chapter 245 (DBZ 51) is partially set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 245, Bulma says that though the ship remodeling will only take 5 days, the language translation won’t be done for 10 days, 5 days after the remodeling ends. She says they’ll leave once that’s finished, 10 days later, so this is that long after the 4th.]

November 21st, Age 762
--Having learned of the Dragon Balls from Vegeta's trip to Earth, Freeza decides to head for Planet Namek and use the ones there to wish for eternal life and youth. He sets off from his base on Planet Freeza No.79 around this time with his aides Zarbon and Dodoria, as well as a number of lower-ranking soldiers.
[Ref: In Chapter 246 when Vegeta arrives on Planet Freeza No.79, one of the mooks there says Freeza has "just left". In Chapter 247 when Bulma and co. reach Namek, Freeza already has 3 Dragon Balls. He's just finished obtaining a 4th, and before long gets a 5th too, so at that rate he probably hadn't been there all that long before Bulma/Vegeta/Kewi arrive. However, since it is apparently a trip of 2-3 weeks, when the mook says Freeza "just left" I suppose this could potentially mean yesterday or the day before.]

--Vegeta reaches Planet Freeza No.79. After his injuries are healed he learns that Freeza has gone to Namek, and immediately sets off for Namek himself to get his hands on the Dragon Balls first.
--DB Chapter 246 (DBZ 52) is partially set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 246 Vegeta is said to reach Planet Freeza 18 days after leaving Earth, so this is that long after the 3rd. At the same time, Bulma says it’s been 7 days since they left, so this is also that long after the 14th. So far so good. But then Bulma says they still have 20 to go, while at the end of the chapter the narrator says they reach Namek the 34th day of their trip. I guess Bulma just miscounted. Daizenshuu 7 has Vegeta’s healing wrap up on December 13th, 22 days after he reaches Planet Freeza, though the chapter gives no indication of that long passing. We know Vegeta reached Namek the same day as Bulma (which Daizenshuu 7 dates as December 18th). I think the assumption here is that Vegeta’s ship must be as fast as Ginyu and co.’s ships, which were capable of reaching Planet Namek in 5 days starting from Planet Freeza No.79. That assumption leaves a 22 day discrepancy: Bulma and co. don’t leave Earth until 11 days after Vegeta does and take 34 days to get there, giving a total of 45 days, whereas Vegeta takes only 23 (18 to Planet Freeza and 5 to Namek), yet they reach there at almost exactly the same time. So that’s why the timeline has Vegeta’s healing take 22 days, to correct the discrepancy. However, I personally think it’s easier to just say that Vegeta’s ship was much slower than Ginyu and co.’s.]

--DBZ Episode 39: Around this time, Bulma and co. encounter the spaceship of orphans. The orphans show them a shortcut to reach Namek.
[Ref: In the episode Bulma says it’s the 7th day of their trip.]

November 24th, Age 762
--DBZ Episode 41-44: Bulma and co. are caught in a space current and crash-land on a planet inhabited by the stranded aliens Raichi and Zarkuro. The two show Bulma and co. illusions of Planet Namek to distract them while they try and steal their spaceship and escape.
[Ref: Japanese Wikipedia’s entry on Raichi and Zarkuro say they encounter Bulma and co. roughly 10 days after Bulma and co. depart Earth. I don’t remember anything about that in the Fake Namek episodes, but I don’t want to bother re-watching them, so I’m going with that date.]

November 28th, Age 762

--DBZ Movie 2: Dr. Kochin uses the Dragon Balls to release Dr. Uiro and his laboratory from the ice. Dr. Uiro tries to implant his brain into the body of the world’s strongest man, but Goku defeats him.
[Ref: While noting it is inconsistent with the main series, Daizenshuu 6 places the movie between Vegeta’s attack (November 3rd) and Goku’s arrival on Planet Namek (December 24th). I’ve arbitrarily set it at the midpoint between these dates.

December 4th, Age 762
--Karin estimated that more Senzu would grow by this time.
[Ref: He says this in Chapter 243, but it apparently takes an extra two weeks.]

December 18th, Age 762
Bulma and co. arrive on Namek
--Vegeta and his rival Kewi also arrive at about the same time. Vegeta begins a rebellion against Freeza, killing Kewi and then Dodoria. Meanwhile Gohan and Kuririn rescue a Namekian child named “Dende” from Freeza’s henchmen. Under Dende’s guidance, Kuririn sets off to meet the Great Elder of Namek. Goku departs for Namek himself, travelling in a remodeled version of the Saiyan spaceship that took him to Earth. Using the ship’s gravity control, he starts training in 30 and then 50 times Earth’s gravity. In the afterlife, Piccolo, Tenshinhan, Chaozu, and Yamcha arrive on the North Kaio’s planet and likewise commence training.
--DB Chapters 246-261 (DBZ 52-67) are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 246 says Bulma and co. reach Namek 34 days after departing Earth, so this is that many days after Nov 14th. Telling when time passes on Planet Namek can be hard, since there’s no night. Everything up to Bulma and co. arriving on Namek to Goku talking with Kaio seems to be set on the same day (which means Goku reaches 50g on his first day of training!). According to Chapter 250 Goku leaves 2 hours after Bulma contacts Kame-sennin, and will reach Namek in 6 days, so that gives a limit to how much time can pass between now and then.]

--DBZ Episode 50: Goku’s spaceship is endangered when it is captured by the gravity of Star αHZ. Goku unleashes a Kamehameha outside the ship, and the recoil gets him out of danger.
[Ref: Date from Daizenshuu 7.]

--DBO: Travelling from the far future, Towa and her Time Breakers attempt to interfere with the events on Planet Namek, but are tailed by the Time Patrol. Towa reanimates Kewi and Dodoria, experimenting on them to increase their size and power, but they prove unstable in their altered forms and are defeated by the Time Patrol.
[Ref: A description of one of the Time Machine Quests in the game.]

December 19th, Age 762
--Freeza’s aide Zarbon beats Vegeta to the brink of death, but takes him back to Freeza’s spaceship to receive medical treatment when he learns Vegeta has hidden a Dragon Ball and is the only one who knows its location. At Freeza’s orders, the Ginyu Special-Squad interrupts its invasion of Planet Yardrat and heads for Namek to assist him.
--DB Chapters 261-264 (DBZ 67-70) are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 264 Freeza orders Ginyu and co. to come to Namek, and it’s said they’ll arrive in 5 days. Since Goku was going to arrive on Namek in 6 days, and he ends up arriving shortly after Ginyu and co., this means that a day has passed since Goku left. The transition into this day probably comes in Chapter 262 when the scene switches back to Namek after Goku’s conversation with Kaio.]

--Towa tries to interfere in Vegeta’s fight with Zarbon, experimenting on Zarbon to increase his size and power. Her experiments again go awry, and the altered Zarbon is defeated by the Time Patrol.
[Ref: A description of one of the Time Machine Quests in the game.]

December 20, Age 762
--After recovering from his injuries, Vegeta escapes Freeza’s ship with the Dragon Balls. Kuririn arrives at the house of the Great Elder, who draws out his dormant power and entrusts him with the Namekian 1-Star Ball. Zarbon tracks Vegeta down and fights him again, but Vegeta is stronger now and kills Zarbon. Kuririn returns to Gohan and Bulma, then sets out again for the Great Elder’s house with Gohan in tow so that the Great Elder can draw out his power as well.
--DB Chapters 264-270 (DBZ 52-76) are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 264 the narrator explains about how Namek has no night, and says about 1 day passes, leading to this day.]

December 22nd, Age 762
--In his spaceship traveling to Namek, Goku collapses while training in 100 times Earth’s gravity, but uses a Senzu to recover.
--DB Chapter 270 (DBZ 76) is partially set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 270 as the scene shifts to Goku’s training, the narrator says “2 days later” (Viz changes this to “meanwhile”). The narrator also says Goku has been in space 4 days, so this is that long after the 18th.]

December 23rd, Age 762
--Goku completes his 100g training in his spaceship. He decides to rest in the remaining time before he reaches Namek.
--DB Chapter 270 (DBZ 76) is partially set on this day.
[Ref: Still in Chapter 270, from that last part with Goku’s training, the narration says that another day passes.]

December 24th, Age 762
The battle with Freeza
--The Ginyu Special-Squad lands on Planet Namek and begins fighting Vegeta, Gohan, and Kuririn. Goku arrives on Namek soon after, and the Ginyu Special-Squad is defeated. Goku is heavily injured in the battle, and is placed in a medical machine to heal for about 40~50 minutes. During that time Kuririn and the others use the Namekian Dragon Balls to summon Polunga, wishing Piccolo back to life and by extension reviving God and Earth’s Dragon Balls. Vegeta, Gohan, Kuririn, and the revived Piccolo (brought to Namek with another wish) battle Freeza, but are outclassed. Vegeta is killed, while Goku finishes healing and confronts Freeza. Ultimately Goku transforms into a legendary Super Saiyan and defeats Freeza, but their fight destroys Namek. Using Earth and Namek’s Dragon Balls, all those killed by Freeza and his henchmen are brought back to life and transported safely to Earth, while Goku escapes the exploding planet with one of the Ginyu Special-Squad’s ships.
--DB Chapters 270-329 (DBZ 76-135) are set on this day. Manga-wise, this is the “longest” day in the series, making up 60 chapters and about 11.5% of the series’ total run.
[Ref: Date from Daizenshuu 7. In Chapter 250 it says Goku will reach Namek in 6 days, so this is that long after the 18th. In Chapter 270, after Goku’s training scene, Freeza says that Zarbon has been gone for 4 days, and Kuririn says it’s been 4 days too, so this is also 4 days after the 20th. Goku healing for 40~50 minutes is from Chapter 291. These events occurring on Christmas Eve may be a reference to a short (5 panels) side manga by Toriyama featured in Weekly Jump No.3-4, 1991, which shows the characters celebrating Christmas in various ways, all where they would be during this point in the Namek/Freeza arc.]

—DBZ Movie 3: Tullece and his men plant the Shinsei-ju on Earth, planning to eat its fruit once again and achieve power rivaling Freeza. They are defeated by Goku, and the Shinsei-ju is destroyed.
[Ref: While noting its inconsistencies with the main series and calling it a “movie-only story”, Daizenshuu 6 says this is between Goku’s arrival on Namek and his showdown with Freeza, both events which are on December 24th.]

--DBZ Movie 4: Slugg and his Demon Clansmen attack Earth, trying to convert the entire planet into their personal spaceship, but Goku defeats them.
[Ref: While noting its inconsistencies with the main series, Daizenshuu 6 places this between Goku’s arrival on Namek and his transformation into a Super Saiyan, both of which are on December 24th.

--DBO: Towa alters Recoom, but like before the Time Patrol defeats her experiment. Towa next has her Time Breakers try to exterminate all Namekian frogs in the region, to prevent Ginyu’s defeat. She plans to take control of Goku’s body while Ginyu’s soul is inside. With Bardock’s help, the Time Patrol foils her plan, defeating the gigantic frog-Ginyu Towa sends after them.
--DBO: After Nail’s battle with Freeza, Towa steals some of his Namekian ki. She infuses it into Freeza’s severed tail, which she feeds to one of Freeza’s henchmen, making him grow in size and power. The Time Patrol defeats the henchman, only for Towa to enhance Ginyu’s body as well, but with similar results. Her various experiments a failure, Towa returns to the future.
[Ref: A description of two of the Time Machine Quests in the game.]

AGE 763
Sometime in Age 763
--Cell from Timeline III arrives in this era by time machine. He burrows underground to develop for the next few years. His goal is to find Androids No.17 and No.18 in this era and absorb them so he can reach his perfect form.
[Ref: Date from Daizenshuu 7. In Chapter 358 Cell is said to have come from the future a year before Trunks did and 4 years before the androids appear, which places it in this year. In Chapter 363 however, Cell says he needed 3 years to grow, and this year-long gap is never explained. Perhaps Cell stayed an extra year underground because he had nothing better to do until the androids showed up?]

--The Ginyu Special-Squad spaceship Goku used to escape from Namek takes him to Planet Yardrat, its pre-programmed location. On Yardrat Goku begins learning the Teleportation technique, which takes him the next year and a half or so.
[Ref: Explained in Chapter 336. For the year number, I’m just arbitrarily assuming it took Goku more than seven days to reach the planet, putting it in this year. Mostly I just didn’t want to add yet another entry for Age 762.]

--Following his battle with Goku, Freeza is rescued from the ruins of Namek by his father Cold. Seriously injured, he undergoes reconstructive surgery to become a cyborg. He and Cold head to Earth to get revenge on Goku.
[Ref: Date from Daizenshuu 7. It labels this and the entry for Cell’s arrival as “sometime in Age 763”, but places them after the entries for May, September, and October, possibly meaning they are supposed to occur in November or December. Still, if they meant such a specific range I think they would have said so, so I’m moving them here to show that their relation to the other events isn’t clear.]

March, Age 763
--According to Goku’s doctor, this is approximately when Goku’s injuries from the battle with Vegeta would have healed, had he not taken a Senzu instead.
[Ref: Chapter 243. The doctor says it will take 4 months, but that Goku might never fully return to normal.]

May 3rd, Age 763
--Kuririn and Yamcha are brought back to life with the Namekian Dragon Balls.
--DB Chapter 329 (DBZ 135) is partially set on this day.
[Ref: Date from Daizenshuu 7. Chapter 329 says that the Namekian Dragon Balls take 130 days to recharge (DBZ Episode 107 refers to this as the length of a Namekian year). Kuririn and Yamcha are revived 130 days after Freeza’s defeat, and then Tenshinhan and Chaozu are revived 130 days later.]

September 10th, Age 763
--Tenshinhan and Chaozu are revived with the Namekian Dragon Balls. The Namekians, who have been spending this time living at Capsule Corporation, use the Dragon Balls to settle on a different planet, which they dub “New Namek”.
--DB Chapter 329 (DBZ 136) is partially set on this day.
[Ref: Date from Daizenshuu 7. Chapter 329 says 130 days pass between Kuririn’s revival and this.]

October, Age 763
--DBZ Episodes 108-116: Planet Makyo approaches Earth for the first time in 5,000 years. The proximity of their ancestral home world powers up the Demon Clansmen dozens of times over, allowing Garlic Junior to escape from the Dead Zone. He uses the Aqua Mist his father stole from the previous God of Earth to convert Earthlings into Demon Clansmen, but the current God and Mister Popo pour the antidote out over the Earth, while Gohan destroys Planet Makyo. His power source gone, Garlic Junior falls back into the Dead Zone.
[Ref: Date from Daizenshuu 7. Episode 108 pegs this as 10 months after Goku and Freeza’s battle, so this is that long after December.]

--DBZ Episode 117: Sea Turtle celebrates his 1,000th birthday. Kuririn tries proposing to his girlfriend Maron, but it doesn’t go well.
[Ref: I’m assuming this episode takes place soon after the rest of the filler arc.]

[Herms]

AGE 764

August, Age 764 (#TRU)
Timeline II and III:

Goku returns to Earth
--Freeza and Cold attack Earth. Returning from Yardrat in his spaceship, Goku Teleports to Earth so he can make it in time to defeat them. At this time, an insectoid spy robot controlled by Doctor Gero’s computer collects cells from Freeza and Cold. The computer adds these to the developing Cell.
--Shortly afterwards, Goku comes down with a virus-based heart disease and dies.
[Ref: In Chapter 335 Trunks explains how things played out in the original timeline. It’s implied that originally Goku Teleported to reach Earth in time. The Trunks TV Special has Goku die about 2 years later, after Trunks’ birth, rather than soon after returning to Earth like the manga says.]

Timeline I:
Trunks appears
--Trunks from Timeline II travels to this era from roughly 20 years in the future. Freeza and Cold attack Earth, and Trunks steps in to defeat them. At this time, an insectoid spy robot controlled by Doctor Gero’s computer collects cells from Freeza and Cold. The computer adds these to the developing Cell.

Goku returns to Earth
--Three hours later Goku returns to Earth, and Trunks warns him of Gero’s androids, which will commence their attack on the world three years from now, on May 12th. He also gives Goku medicine to prevent him from dying from the heart disease he should soon come down with. Trunks returns to his own timeline, while Goku and the others begin training to defeat the androids. Staying at Capsule Corporation, Vegeta has Briefs build him a gravity control room, which he uses to train to become a Super Saiyan.
--DB Chapters 329-336 (DBZ 136-142) are set on this day.
[Ref: Date from Daizenshuu 7. The spy robot is mentioned in Chapter 363. In Chapter 329, the narrator says that “about a year” passes between the Namekians leaving Earth and Trunks’ arrival (Viz ambiguously phrases this narration so that it could also be interpreted as meaning that a year has passed over the course of the entire chapter; ie between Freeza’s defeat and Trunks’ arrival). Since the Namekians leave on September 10th of the previous year, the Daizenshuu 7 date has Trunks appear about 11 months later. The opening narration of DBZ Episode 118 refers to Goku and Freeza’s battle as a year prior to Freeza’s attack on Earth. On the flipside, DBZ Episode 171 says Gohan turned 11 when training in the ROSAT, which only really works if about 2 years pass between the Freeza arc and Trunks’ arrival. Anyway, I’ve chosen to just ignore the anime’s “1 year between Freeza/Trunks” thing rather than create a separate anime timeline for everything after this, one where everything’s simply a year earlier than the manga version.]

Sometime later in Age 764
--DBZ Episode 125: Goku and Piccolo go to driving school to obtain air car licenses.
[Ref: The episode refers to the androids as attacking in 3 years, so it can’t be too long since Trunks’ warning.]

AGE 764 to AGE 767
--Bulma dumps Yamcha for being (she says) unfaithful. She begins to fall in love with Vegeta. However, they do not marry.
[Ref: Trunks explains this in Chapter 335.]

--As Goku trains with Gohan and Piccolo, he never exhibits the symptoms of his heart virus, and so never takes the medicine Trunks gave him.
[Ref: Gohan explains this in Chapter 342.]

--DBZ Movie 5: Freeza’s brother Coola invades Earth and battles Goku. Ultimately Goku transforms into a Super Saiyan and knocks Coola into the sun.
[Ref: Date from Daizenshuu 7. Daizenshuu 6 places this movie between Trunks’ first visit (August 764) and the androids’ attack (May 767), which is probably where Daizenshuu 7 gets its date from.]

--After creating the purely mechanical Android No.16, Doctor Gero returns to making androids by restructuring flesh-and-blood humans. Seeking fresh subjects for his experiments, he kidnaps twin siblings, both notorious delinquents, who he makes his next test subjects. He modifies them primarily via organic parts, using infinite energy reactors as their power sources so that their energy never decreases. Both twins hate Gero for turning them into androids. The boy becomes Android No.17, but because Gero places too much emphasis on his power he is insubordinate. The girl becomes Android No.18. Gero suppresses her power more compared to No.17, but she too ends up insubordinate. Eventually Gero ends up shutting them both down, so that he can modify their personalities to be more obedient. In the meantime, wanting eternal life he decides to turn himself into an android. To help with this operation he creates another purely mechanical android, No.19, who has no infinite energy reactor and must instead absorb energy from others. This leaves him weaker than Nos 16-18, but also makes him easier to control. Gero becomes Android No.20, also an energy-absorbing model, and plans to finally confront Son Goku and co. with No.19’s help.
[Ref: Most of this is from Chapter 350 and Chapter 367’s title page. 17+18 have never seen Gero as an android before, so this must have happened since the last time he shut them down. In Chapter 351 No.17 wonders why Gero would have “returned” to making human-based androids if he could make ones from scratch; why is never really explained. 17+18’s infinite energy is explained in Chapter 347, and their being modified mostly through organic parts is in Chapter 365. 17+18 being twin delinquents is from Toriyama’s “character secrets” page in Daizenshuu 7. For the dating, in Chapter 336 Bulma and Goku assume that Gero has not created the androids Trunks warned them about yet. There’s no real way they could know this, but regardless I’m assuming Toriyama meant their “Gero hasn’t done anything yet” argument to have some validity, and that therefore 17+18 weren’t made until after Trunks warns Goku of them…Well, he actually warns Goku of 19+20, but that gets retconned.]

AGE 766
--Bulma and Vegeta’s son Trunks is born this year. Though a Saiyan/Earthling hybrid, he has no tail.
[Ref: Date from Daizenshuu 7 and SEG: Character Volume. In Chapter 335 Trunks says he will be born “about two and a half years from now”. Trunks also notes that the androids will attack in 3 years on May 12th. If there’s about 6 months between Trunks’ birth and May 12th of the next year, presumably his birth is fairly late in the year. In Chapter 433 Trunks is said to be 8 during the 25th TB in 774. Daizenshuu 4 says Trunks and Goten are born without tails; in Chapter 337 Kuririn asks Bulma if they cut baby Trunks' tail off, but her answer isn't shown.]

AGE 767
--Pilaf and his gang were going to make another attempt at world domination in this year, but the events surrounding Cell force them to postpone their plans.
[Ref: Toriyama says this in his “character secrets” page, on page 122 of Daizenshuu 7.]

May 7th, Age 767
The 24th Tenkaichi Budokai
--A new “youth division” is introduced for children 15 and younger. Mark (now going by the ring name “Mister Satan”) is the champion of the adult division, and Jewel is runner-up. Mighty Mask and Spopovitch lose in the first round, Killer loses in the second round, while Punter loses in the semi-finals. Mark’s daughter Videl is the youth division champion.
[Ref: Date from Daizenshuu 7. In Chapter 425 Videl says her father won the last tournament, and Goku won the one before that. Since Goku won the 23rd, this makes the one Satan won the 24th, though this number is only ever used in guidebooks. In Chapter 439 as Videl starts to fight Spopovitch, the tournament announcer says the previous tournament was 7 years ago, placing it in this year. The month and day is the eternal one for the TB. When Satan is introduced in Chapter 393, he’s described as the “world martial arts [kakutou] champion”, while in Chapter 425 Videl says the TB determines the “world martial arts [kakutou] champion”. This might be Toriyama trying to imply Satan’s fame during the Cell Games was due to him winning the TB, particularly since previously “budou” rather than “kakutou” had been the word used for the martial arts when talking about the Tenkaichi Budokai (hence the name). Chapter 425 establishes Videl as champion of the youth division, as well as Spopovitch losing in the first round (the anime shows him losing to Mister Satan). Mighty Mask, Jewel, and Killer’s placement comes from Chapter 458. The mention of both a "second round" and the "semi-finals" could mean that this tournament had 4 rounds, unlike previous TBs but like the 25th. Gohan (16, according to the narrator) can enter the adult division, but Idasa (said to be 15) is in the youth division, so apparently the cutoff point is around there.]

Roughly around May 8th~10th, Age 767
--Capsule Corporation receives inquiries from a man who stumbled upon an abandoned Capsule Corporation vehicle out in the west. This later proves to be the time machine Cell used to reach this era.
[Ref: In Chapter 357, Bulma (on May 12th) says this was several days ago.]

May 12th, Age 767 (#CEL)
Timelines II, III:

The androids attack
--Gero’s androids attack an island nine kilometers southwest of South City. No.17 and No.18 kill Doctor Gero and begin rampaging on their own. In the resulting battle most of the Earth’s strongest warriors die, including Vegeta, Kuririn, Yamcha, Tenshinhan, Chaozu, and Piccolo. Gohan survives, and begins training to defeat the androids. In the following years, the androids continue killing people for sport. Though they draw the process out to prolong their fun, within 17 years Earth’s population is reduced to the tens of thousands. West City is mostly destroyed, and the survivors live in underground shelters.
[Ref: Trunks explains this in Chapter 336 and 358. It’s unclear whether No.19 and No.20 appeared in the original timeline. They’re the ones Trunks originally explains about, but Toriyama later retcons this so that Trunks doesn’t even know about them. It is however possible that they did appear and were destroyed as quickly as in the main series, and so Trunks never learned of them.]

Timeline I:
The androids attack
--Androids No.19 and No.20 attack an island nine kilometers southwest of South City. In the resulting battle, Goku passes out from his heart disease, while Vegeta (now a Super Saiyan) destroys No.19 and chases No.20 back to his lab. No.20 awakens No.17 and No.18, but they kill him and awaken No.16. Vegeta and co. are defeated by No.18 and No.17, but the two are not interested in killing them, only Goku. Piccolo goes to God’s temple and asks God to merge with him to create a warrior powerful enough to stop the androids.

Cell appears
--Bulma, Trunks, and Gohan investigate Cell’s time machine, and shortly afterwards Cell attacks Ginger Town. God and Piccolo merge and go to fight Cell, but he escapes. Later Kuririn and Trunks go to Gero’s lab and destroy Timeline I’s Cell, still in development. They find the blueprints for No.17, which Trunks gives to Bulma.
--DB Chapters 336-365 (DBZ 142-171) are set on this day.
[Ref: In Chapter 335 Trunks tells Goku the androids will appear on May 12th in three year’s time. The year number is from Daizenshuu 7.]

May 13th-14th
--Cell travels the world absorbing people to gain the strength he needs to overpower No.17 and No.18 and merge with them. He continues to evade Piccolo and the others by masking his ki. In the wilderness, Vegeta stares off into space, imagining how to surpass Super Saiyan.
[Ref: Cell outlines his plan in Chapter 364 and in Chapter 365 a news report describes Cell’s activity. In Chapter 366 Trunks tells Goku that Vegeta has been standing around for the last 3 days.]

—DBZ Movie 7: Following Gero’s death, his computer completes Androids No.13, No.14, No.15, who come after Goku. After No.14 and No.15 are destroyed, No.13 absorbs their parts and powers up, but Goku defeats him with the energy from a Genki-Dama.
[Ref: While saying that the movie can be called the “events of a parallel world”, Daizenshuu 6 places it between Gero’s death (May 12) and Cell reaching his perfect form (May 16). I’m arbitrarily sticking it here

May 15th, Age 767
--Goku finally recovers from his hearts disease thanks to the medicine Trunks brought him from the future. He tells the others of the Room of Spirit and Time, and Vegeta and Trunks enter it to train.
--DB Chapters 365-366 (DBZ 171-172) are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 365 the narrator says 3 days have passed, and Trunks says so too in Chapter 366. Back in Chapter 355 Trunks says it will take Goku “about 10 days” to recover, but apparently he underestimated Goku’s heartiness.]

May 16th, Age 767
--By now Cell has absorbed hundreds of thousands of people. Still searching for Goku, Nos 16-18 arrive at Kame House. Piccolo tries to fight them off, but Cell arrives and manages to absorb No.17, evolving into his second form. Vegeta and Trunks exit the Room of Spirit and Time, allowing Goku and Gohan to enter and begin their own training. Vegeta catches up with Cell as he chases after No.18, and easily outclasses him with the results of his training. Bored, he allows Cell to absorb No.18 and evolve into his perfect form. This gives Cell the power to defeat Vegeta and Trunks. Cell announces his plans to hold a tournament in 10 days, to give them all a second chance to defeat him.
--DB Chapters 366-388 (DBZ 172-194) are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 366 the narrator says “almost a full day” passes between Vegeta and Trunks entering the Room of Spirit and Time and when No.17 and co. show up at Kame House, and a news report mentions Cell’s body count. In Chapter 388 Cell says his tournament will be in 10 days.]

May 17th, Age 767
--Cell attacks Central City, hijacking a TV broadcast to announce the “Cell Games” to the entire world. This will be a tournament held in nine days to decide the fate of Earth; if nobody can defeat him in it, he will exterminate all Earthlings. Goku and Gohan emerge from the Room of Spirit and Time, three hours short of a full day. Learning the situation, Goku regardless declines to train in the room again, saying it would be better for him and Gohan to spend the remaining days resting. Piccolo instead enters the room to train on his own.
--DB Chapters 389-391 (DBZ 195-197) are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 389 the narrator says Cell's TV broadcast comes “the next day” after Cell reaches his perfect form. In Chapter 390 Popo says Goku and Gohan emerge 3 hours short of a full day. Also in Chapter 390, Piccolo tells Goku about the training order for the Room of Spirit and Time: Piccolo will go in first (on that same day), then Vegeta the next day, and then finally Trunks.]

May 18th, Age 767
--Switching out with Piccolo, Vegeta once again enters the Room of Spirit and Time, this time training alone.
[Ref: Date from Daizenshuu 7. Piccolo says in Chapter 390 that Vegeta will go in on his own the next day.]

--DBZ Episode 171: Gohan meets Lime, a young girl whose parents were killed by Cell. He helps drive the swindler Bourbon from her village.
[Ref: Date from Daizenshuu 7. The episode says the Cell Games are 8 days away, meaning it’s the day after their announcement.]

--DBZ Episode 172: Since Gohan has turned a year older while training in the Room of Spirit and Time, everyone celebrates his birthday.
[Ref: This episode also says the Cell Games are 8 days away, putting it likewise on this day. Chi-Chi says Gohan is now 11.]

May 19th, Age 767
--Still trying to relax before the tournament, Goku and his family go hiking. Around noon, the Earth’s Royal Army attacks Cell, but is wiped out. On TV Earth’s King apologizes for this failure, while Tenkaichi Budokai champion Mister Satan announces his participation in the Cell Games. To revive Earth’s Dragon Balls, Goku Teleports to New Namek and recruits Dende to be the new God of Earth. Dende uses his skills as a Dragon Clan Namekian to restore the Dragon Balls, making them so that they can grant three wishes, unless one wish is used to resurrect many people at once, in which case only a total of two wishes may be granted. Switching out with Vegeta, Trunks enters the Room of Spirit and Time to train on his own.
--DB Chapters 392-394 (DBZ 198-200) are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 392 Chi-Chi says nobody is working since they figure they’ll all be dead in 7 days, placing this that long before the Cell Games. In Chapter 394 Dende seems to imply the new Dragon Balls will only grant two wishes, but in Chapter 473 this is apparently retconned to be that they can typically grant three, but only two if one wish revives many people. Trunks entering the ROSAT is from Piccolo’s Chapter 390 explanation of the schedule.]

--DBZ Episode 174: While gathering Dende’s revived Dragon Balls, Goku encounters the gangster Vodka, who has bought some Dragon Balls from Tao Pai-Pai. To stall Goku, Tao Pai-Pai gives him some puzzles, and he and Vodka make their escape.
[Ref: The episode shows Vegeta coming out of the Room of Spirit and Time, placing it on this day.]

May 20th, Age 767
--Trunks finishes his training in the Room of Spirit and Time.
[Ref: Date from Daizenshuu 7. Again, this comes from the schedule outlined in Chapter 390.]

--DBZ Episode 174: Having spent the entire night solving Tao Pai-Pai’s puzzle, Goku Teleports to him and Vodka and gets their Dragon Balls.
[Ref: If the episode began on the 19th, that puts its ending here.]

May 21st~May 22nd, Age 767

—DBZ Movie 6: Goku and co. travel to New Namek and battle Coola, who has returned as a series of robot copies after merging with the Big Gete Star, a mechanical planet.
[Ref: Daizenshuu 6 places this between the announcement of the Cell Games (May 17) and their opening on May 26. I’ve arbitrarily placed it at about the midpoint of those dates.]

--DBZ Movie 8, 10: The Saiyan survivor Paragus lures Vegeta to “New Planet Vegeta” to be its king, but this is just part of his scheme for universal domination and revenge against Vegeta’s father. Paragus is ultimately killed by his son Broli, who goes mad and becomes a seemingly unstoppable Super Saiyan, but Goku absorbs energy from his companions and defeats him. Broli survives, and though heavily injured makes his way to Earth, where he ends up frozen at the bottom of a lake for the next seven years.
[Ref: While noting that Goku and co.’s leisurely behavior in the movie is “a mystery” in light of this supposedly being right before the Cell Games, Daizenshuu 6 places this between Cell reaching his perfect form (May 16) and the end of the Cell Games (May 26). I’ve arbitrarily placed it at about the midpoint of those dates. The events of the movie itself takes place over 2 days: the first day everyone reaches New Planet Vegeta, during the night Broli attacks Goku, and the next day is the big fight with Broli. Traveling via Teleportation Goku reaches New Planet Vegeta later than the others who went there by ship, so presumably the ship ride couldn't have taken very long. DBZ Movie 10 establishes that Broli has been frozen 7 years, placing his arrival on Earth not long after his first appearance.

May 23rd, Age 767

DBZ Plan to Eradicate the (Super) Saiyans: The Tsufruian scientist Dr. Raichi attacks Earth to gain revenge on the Saiyans, using the hatred amplification device Hatch-Hyack to create “Ghost Warriors” of those killed by the Saiyans. Raichi is actually long-dead and a Ghost Warrior himself. Eventually he and Hatch-Hyack are defeated by Goku and co.
[Ref: The video game/visual guide/OVA/bonus special thingy is obviously set sometime in the Cell Games era, based on Gohan’s design and the presence of future Trunks. Goku describes Hatch-Hyack as possibly stronger than Broli, placing it after DBZ Movie 8. The date here is based off that, but otherwise arbitrary. Somewhat interesetingly, Daizenshuu 7’s timeline mentions Raichi and Hatch-Hyack during its entry on the Saiyan/Tsufruian war, but doesn’t include the main events of PtEtS (ie Goku and co. vs Raichi). Of course, like DBZ Movie 8 it’s difficult to impossible to squeeze these events into the days leading up to the Cell Games. Maybe Goku could have beaten Cell is he hadn’t worn himself out beforehand defeating every other menance in the universe that week?]

May 26th, Age 767
The Cell Games
--The tournament begins at exactly noon. Mister Satan quickly loses to Cell, while Goku puts up a good fight but resigns, appointing Gohan as the next fighter. Wishing to see Gohan’s true power, Cell gives birth to “Cell Juniors” that attack Goku and co. When Cell kills No.16, Gohan finally snaps, transforming into a state beyond Super Saiyan. He quickly kills the Cell Juniors and hits Cell so hard that he vomits out No.18, reverting to his second form. Cell tries to self-destruct and take the entire Earth out with him, but Goku Teleports Cell to the North Kaio’s planet. Cell explodes, killing Goku, North Kaio, and Bubbles, but Cell himself manages to survive, regenerating into a powered-up version of his perfect form. He returns to Earth (having learned Goku’s Teleportation technique) but with Goku’s encouragement and Vegeta’s help Gohan obliterates Cell with a Kamehameha. Mister Satan takes credit for defeating Cell, and becomes a world hero.
--DB Chapters 394-418 (DBZ 200-224) are set on this day.
[Ref: Date from Daizenshuu 7. In the tankoubon release of the manga (and by extension Viz’s translation), in Chapter 389 Cell says the Cell Games will be on “M 17th”. However, the androids were supposed to arrive on May 12th. Between various bits of narration and Cell saying the tournament will be 9 days after his TV announcement, the total amount of time between the androids’ initial attack and the Cell Games is locked in pretty firmly as 14 days, meaning either the Cell Games should be May 26th or the androids should show up on “M 3rd”, whenever that would be. Daizenshuu 7 goes with the former approach, and the kanzenban release of the manga follows suit, changing Cell’s speech so that he says the Cell Games will be on May 26th.]

--DBZ Movie 9: Due to the North Kaio’s death, Bojack is freed from his prison inside a planet at the edge of the universe.
[Ref: From Kaio’s explanation in the movie.]

May 27th, Age 767
--A memorial service is held for Goku, and Trunks returns to Timeline II.
--DB Chapter 418 (DBZ 224) is partially set on this day.
[Ref: Date and the “memorial service” bit are from Daizenshuu 7. In Chapter 418 as the Cell Games wrap up, Trunks says that he will return to his future the next day. No memorial service for Goku is explicitly mentioned in the manga, but everyone is shown wearing mourning clothes when they see Trunks off.]

May~June, Age 767
--DBZ Episode 194: On Earth, baby Trunks takes his first steps. A TV special is broadcast celebrating Mister Satan as the hero who saved Earth.
--DBZ Episodes 195-199: In the afterlife Goku travels to the Grand Kaio’s world to train. The Grand Kaio requests that he and Paikuhan, a warrior from the West Galaxy, go to Hell and take care of Cell, Freeza, and other dead evil-doers who are causing trouble there. When they get back, the four Kaios all gather and decide to hold the “Strongest in the Afterlife Tournament” to celebrate North Kaio’s death. The contestants are all dead warriors allowed to keep their bodies in the afterlife, and the championship prize is to be personally trained by the Grand Kaio. In the final eight, Marraiko defeats Frog, Goku defeats Arqua, Tolbe defeats Tapikar, and Paikuhan defeats Olivu. In the semi-finals Goku defeats Marraiko, and Paikuhan defeats Olivu. During the finals Goku seems to defeat Paikuhan, but the Grand Kaio declares the match a draw on a technicality (he really just doesn’t want to train either of them).
[Ref: Date from Daizenshuu 7. The afterlife tournament being set from May to June is presumably in reference to Goku dying in late May. Trunks’ first steps and the Mister Satan special are likewise shortly after the Cell Games.]

June~December, Age 767
--Son Goku and Chi-Chi’s second son, Son Goten is born. Though a Saiyan/Earthling hybrid, he has no tail.
[Ref: Year from Daizenshuu 7 and SEG: Character Volume. I’m assuming he’s born after the Cell Games. In Chapter 433 Goten is said to be 7 years old during the 25th TB (in Age 774), which is itself described as 7 years after the Cell Games. The narrator says in Chapter 424 that Goten was left behind “before the battle with Cell”. Many people assume this refers to the 9 days leading up to the Cell Games, though for him to be born in 767 he would have to have been conceived by no later than March, while the Cell Games are said to be in May. I suppose that, as a half-alien hybrid, Goten’s gestation time could have been shorter than 9 months, but I prefer to think “before the battle with Cell” means before the day the androids and Cell appear, which gives a little more leeway. Daizenshuu 4 says Trunks and Goten were born without tails.]

--DBZ Movie 9: Ultra-rich Gyosan Money holds a tournament in honor of his son’s birthday, while Bojack and his underlings pick this time to attack Earth. Gohan defeats them, but Mister Satan takes the credit.
[Ref: Daizenshuu 6 says this is “several months after the Cell Games”.]

AGE 768 to AGE 774
--While training in the afterlife, Goku masters the form of Super Saiyan that surpasses regular Super Saiyan, which Gohan had earlier reached during the Cell Games. He dubs this “Super Saiyan 2”. What’s more, after additional years of training he reaches an even stronger form, which he terms “Super Saiyan 3”. On Earth, Vegeta also acquires the Super Saiyan 2 form through harsh training.
[Ref: Goku implies “Super Saiyan 2” and “Super Saiyan 3” are provisional terms in Chapter 474. In Chapter 493 he says it took him years to reach Super Saiyan 3. The Daizenshuu 7 technique dictionary entry for Super Saiyan 2 says Vegeta acquired the form through training. The date is just the gap between the Cell and Boo arcs.]

--In the afterlife Goku encounters two martial artists from Planet Metamor. They teach him their planet’s specialty technique, “Fusion”, which allows two people of similar size and power to temporarily merge into one and greatly power up. Though he masters the technique, Goku is unable to actually try it out, as there is nobody in the afterlife sufficiently close to him in power.
[Ref: Goku explains this in Chapter 469. The date is just the gap between the Cell and Boo arcs.]

AGE 769
--DBZ Movie 12: A grandfather dies.
[Ref: His ghost appears in the movie, saying he died 5 years ago.]

AGE 770 (#770)
Kuririn and No.18 get married.
--Though initially aloof, No.18 had never met someone as honest and unsophisticated as Kuririn, and in time she gradually falls for him.
[Ref: Date from Daizenshuu 7. This is one year before Marron’s birth. The description is from Toriyama’s explanation of how they got married, from the Daizenshuu 7 “character secrets” page.]

AGE 771
--Kuririn and No.18’s daughter Marron is born. She initially has no nose, like her father, but she later grows one during puberty.
[Ref: Date from Daizenshuu 7, which also mentions her growing a nose during puberty in her bio. We do in fact see in the series that she has no nose as a little girl but has one when older. Like with the timing of Vegeta or Gohan’s birth, DB couples always seem to have kids right away. Marron’s name isn’t mentioned until the title page of Chapter 518. Due to the anime-only character Maron, in the anime it ends up seeming like Kuririn named his daughter after his old girlfriend. Both names derive from French for “chestnut”; Kuririn is in part named after the Japanese word for chestnut. Most likely Toriyama and the anime staff independently came up with this name as a fitting one for someone connected to Kuririn.]

AGE 773
--Kaioshin and Kibito come to Earth to search for Majin Boo’s ball, which was left there five million years ago. They discover that Babidi has moved it.
[Ref: Date from Daizenshuu 7. In Chapter 445 Kibito says that they have learned of Babidi “just recently”, though what that means for people millions of years old is unclear. This is a year before the Boo arc.]

AGE 774
Timelines II, III:

--Though the details are unclear, Babidi is unable to revive Majin Boo at this time due to the absence of beings with powerful energy on Earth.
[Ref: The Daizenshuu 7 alternate timeline explanation page gives this as the reason Babidi doesn’t turn up in Trunks/Cell’s timelines.]

--The dog Bee is born sometime this year prior to May.
[Ref: Year from his Daizenshuu 7 bio. Boo finds him in May, so he must be born before that.]

--Pilaf and his gang were thinking of finally making another move for world domination in this year, but the events surrounding Majin Boo force them to postpone their plans.
[Ref: Toriyama says this in the Daizenshuu 7 “character secrets” page.]

March 28th, Age 774
--Gohan completes the first part of the enrollment process for Orange Star High School, a school in Satan City. He defeats some criminals, turning into a Super Saiyan to prevent people from recognizing him. This gives rise to rumors of a “Golden Warrior”.
[Ref: Date from Daizenshuu 7. In Chapter 422, on Gohan’s first day of school (April 7th), Erasa tells him that the Golden Warrior was seen 3 time in the last 10 days. Gohan thinks to himself that the first two times where when he came to Satan City to enroll. So this is 10 days before April 7th.]

April 7th, Age 774 (#BOO)
--Gohan is enrolled at Orange Star High School, and attends his first day of class. He meets Videl after fighting more crime as the “Golden Warrior”. Realizing he needs a better disguise, on his way home from school Gohan stops by Bulma’s house and requests she make a “transformation suit.” Bulma takes two hours to make it, finishing at 5:12 PM, and Gohan makes his first appearance in Satan City as the “Great Saiyaman”. That night, Gohan practices heroic poses for two hours.
--DB Chapters 421-423 (DBZ 227-229) are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 426 establishes this as 7 years after the Cell Games. In Chapter 425 the TB is a month away, so this is a month before May 7th, the eternal date for the TB. In Chapter 423 Bulma says making the suit will take 2 hours, and the time “5:12” is seen on Gohan’s transformation watch as he first uses it. Gohan practicing for 2 hours is mentioned in Chapter 424. In Chapter 421 the narrator says Gohan is now 16. Going by his official birth year, or just counting up from him being 4 during Raditz’s attack, gets the result that he should be 17 by this year (and physically 18, counting his year in the ROSAT). Presumably his birthday is sometime after April (and indeed, Daizenshuu 7 places his birthday in May). Also note that Gohan, like Bulma, starts school in April, in keeping with the Japanese education system. Daizenshuu 7's timeline describes Gohan as entering the "sophomore year" at Orange Star, but I'm not sure what that's based on.]

April 8th, Age 774
--Videl and the Great Saiyaman team up to stop some bank robbers, and Videl uncovers the Great Saiyaman’s identity. She uses this information to blackmail Gohan into entering the Tenkaichi Budokai, and to train her to fly via Bukujutsu. Learning of the tournament from the afterlife, Goku announces that he will return to the living world for one day via Uranai Baba’s powers.
--DB Chapters 424-426 (DBZ 230-232) are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 424 someone says the Great Saiyan made his first appearance yesterday. From there it goes straight to the incident where Videl discovers Great Saiyaman’s identity. In the anime though, a minimum of two weeks pass before Videl proves his identity (two Sundays go by). In Chapter 425 Videl says that the 25th TB is a month away, and in Chapter 426 Gohan asks Goten to help him train tomorrow.]

Anime version of Great Saiyaman story arc:

March 25th (Monday), Age 774
--DBZ Episode 201: Gohan enrolls at Orange Star High School, and attends his first day of class. He meets Videl after fighting more crime as the “Golden Warrior”. Realizing he needs a better disguise, on his way home from school Gohan stops by Bulma’s house and requests she make a “transformation suit.” Bulma takes two hours to make it, finishing at 5:12 PM, and Gohan makes his first appearance in Satan City as the “Great Saiyaman”.
[Ref: The events for this day are the same as the manga version, but the later episodes have Videl take a long time to finally figure out the Great Saiyaman’s identity for sure, while in the manga it takes her about 8 seconds. I’ve set the day Videl confronts Gohan with his secret as April 8th, the same as the manga version, and then just extended things backwards from there. This way the date of the tournament remains May 7th.]

March 26th (Tuesday), Age 774
--DBZ Episode 201: Gohan helps Videl save a busload of old folks from some hijackers.
[Ref: Gohan’s classmates say the Great Saiyaman first appeared yesterday.]

March 30th (Saturday), Age 774
DBZ Episode 202: One of Gohan’s classmates, “Angela”, has a crush on him. She claims to have discovered his “secret”, and blackmails Gohan into going on a date with him.
[Ref: The episode begins at night and shows Gohan practicing poses, but I’m going to assume this is the end of the same day seen in the prior episode. It then shows Gohan at school the following morning, when Angela makes him promise to take her out on a date tomorrow, which she says is Sunday. This is another reference in DB to how Japanese schools typically have class on Saturday.]

March 31st (Sunday), Age 774
--DBZ Episode 202: Gohan takes Angela out on a date, but it turns out the “secret” she meant was that Gohan wears silly underwear, and she didn’t actually know anything about the Great Saiyaman.
[Ref: This is said to be Sunday and the next day.]

April 1st (Monday), Age 774
--DBZ Episode 202: Angela already has new crush.
[Ref: The episode’s ending scene seems to be the very next day.]

April 2nd (Tuesday), Age 774
--DBZ Episode 203: Gohan encounters some members of the Red Shark Gang, but lets them hit him when he realizes Videl is watching.
[Ref: It’s not clear how much time has passed since last episode, but I’m assuming for convenience’s sake that this is just the next day after last episode.]

April 3rd (Wednesday), Age 774
--DBZ Episode 203: The Red Shark Gang takes the mayor of Satan City hostage, but Videl and Great Saiyaman defeat them.
[Ref: Gohan was heading home from school when he first encountered the Red Sharks, then there’s another school scene and the gang takes the mayor hostage, so it must at least be the next day.]

April 4th (Thursday), Age 774
--DBZ Episode 204: Gohan and Goten check up on “Chibi”, a newly-hatched baby dinosaur who lives in the wilderness near their house.
[Ref: This isn’t shown in the episode, but Goten says they did this 2 days ago. By extension, this is 3 days before Sunday (as explained below). There’s no particular reason why this couldn’t have been the same day as one of the earlier episodes, but by treating this as the day after the end of Episode 203, it makes this 4 days since the last Sunday (when Gohan’s date was), so it all fits conveniently together.]

April 6th (Saturday), Age 774
--DBZ Episode 204: Gohan discovers that Chibi has been kidnapped by an unscrupulous circus manager, and will be on display tomorrow.
[Ref: This is the actual start of the episode. Goten says they checked on Chibi 2 days ago, and the circus commercial says tomorrow is Sunday.]

April 7th (Sunday), Age 774
--DBZ Episode 204: Gohan rescues Chibi as the Great Saiyaman, which brings him into conflict with the police and Videl. Chibi’s gigantic dinosaur parents arrive in the city and retake their child. During the ruckus, Videl figures out that the Great Saiyaman is Gohan.
[Ref: As explained above. This setup of mine makes April 7th a Sunday in the anime, while in the manga it’s a school day, but since the whole idea is that the anime has a different timeline I don’t think it’s too big a deal.]

April 8th (Monday), Age 774
--DBZ Episode 204: Having discovered that Gohan is the Great Saiyaman, Videl uses this information to blackmail him into entering the Tenkaichi Budokai, and to train her to fly via Bukujutsu. Learning of the tournament from the afterlife, Goku announces that he will return to the living world for one day via Uranai Baba’s powers. While heading home, Gohan stumbles upon the set of an upcoming Great Saiyaman movie.
[Ref: This is the date Daizenshuu 7 gives for the manga version of the day Videl blackmails Gohan. Videls refers to Chibi’s parents’ rampage as “yesterday”, and says the tournament is a month away.]

April 9th, Age 774
--Gohan and Goten begin to train for the tournament, but Videl soon shows up, so Gohan begins teaching her and Goten Bukujutsu. By the end of the day, Videl is already managing to float off the ground, while Goten is easily zooming around. Gohan advises Videl to cut her hair short to make it easier to fight. In the afterlife, the South Kaio observes Goku’s training under North Kaio.
--DB Chapters 426-428 (DBZ 232-234) are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 426 establishes this as the next day after Videl blackmails Gohan. In Chapter 428 Kaio says the tournament is in 28 days.]

April 10th, Age 774
-- Having cut her hair short, Videl continues to train with Gohan. While training for the tournament, Vegeta is surprised to learn that his son Trunks is already capable of becoming a Super Saiyan, and flat-out annoyed to learn Goten can too.
--DB Chapters 428-429 (DBZ 234-235) are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 428 shows Videl showing up with her new haircut “the next morning”.]

April 20th, Age 774
--Videl masters Bukujutsu. Satisfied, she leaves Gohan and Goten to train on their own until the tournament.
--DB Chapter 429 (DBZ 235) is partially set on this day.
[Ref: Date from Daizenshuu 7. The narration in Chapter 429 (which is apparently by Gohan) says Videl masters Bukujutsu ten days after she shows up with short hair.]

Roughly April 21st to May 6th, Age 774

DBZ Movie 10: While searching for the Dragon Balls, Videl, Trunks, and Goten encounter Broli, who has awakened after being frozen on Earth the last 7 years. With the help of Gohan and a phantom of Goku, Broli is killed.
[Ref: Daizenshuu 6 says this is “right before” the 25th TB, citing Videl’s short hair. She seems to know Bukujutsu pretty well in the movie too, so I’m using this range.]

May 7th, Age 774
The 25th Tenkaichi Budokai
--To enter it, Goku returns to the living world for a single day. Babidi’s henchmen Yamu and Spopovitch enter the tournament to gather energy to revive Boo. Tailing them, Kaioshin (calling himself “Shin”) and Kibito also enter the tournament. In the youth division, Trunks defeats Idasa, and Goten defeats Ikose. Ultimately the youth division champion is Trunks, and Goten is runner-up. The two disguise themselves using Mighty Mask’s costume and enter the adult division. In Match 1 of the main tournament, Kuririn defeats Punter, in Match 2 Piccolo resigns to Shin, and in Match 3 Spopovitch brutally beats Videl. Gohan faces Kibito in Match 4, but Spopovitch and Yamu intrude and steal his energy, which they take to Babidi to revive Boo. Goku and co. follow Kaioshin in pursuit, abandoning their matches. The tournament format is therefore switched to a Battle Royale. No.18 defeats “Mighty Mask”, and throws her fight with Mister Satan for a hefty sum. Satan is champion, with No.18 runner up.

Majin Boo is revived
--Meanwhile Goku and co. enter Babidi’s ship, defeating his henchmen Pui-Pui and Yakon, but Gohan struggles fighting Dabra. Growing impatient, Vegeta purposefully falls under Babidi’s spell so he can have his long-desired rematch with Goku. As they fight, their energy is channeled into Boo’s ball, reviving him at full power. Boo kills Dabra and seriously injures Kaioshin and Gohan, and Vegeta self-destructs in an attempt to stop him. Boo revives though, and he and Babidi begin destroying Earth’s cities. Not knowing the still-present danger, Bulma and co. gather the Dragon Balls and revive those Vegeta killed prior to his fight with Goku. With an extra wish still remaining, Goku dismisses Shen Long so that they can use the Dragon Balls again in only four months.
--Kaioshin takes Gohan to the Kaioshin Realm, where Gohan successfully pulls out the Z Sword and begins training with it to defeat Boo. On Earth Goku begins teaching the Fusion technique to Goten and Trunks for the same purpose. He fights Boo as a Super Saiyan 3, which uses up all his energy. This forces him to return to the afterlife early, where he reunites with Gohan. Boo rebels and kills Babidi, settling down in a house of his own design.
--DB Chapters 430-478 (DBZ 236-284) are set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 478, after Goku meets up with Gohan in the Kaioshin Realm, the narrator says a full day passes. The Dragon Balls reviving in 4 months is from Chapter 469; Chapter 517 says they revive in half a year instead.]

May 8th, Age 774
--Since being freed the day before, Majin Boo has already destroyed most of the Earth’s cities and population. He gives sight to a blind boy he happens to meet, but otherwise continues his mindless killing. In the Kaioshin Realm Gohan breaks the Z Sword, releasing the East Kaioshin of 15 generations ago (aka “Elder Kaioshin”), who begins his 25-hour ritual to draw out Gohan’s dormant power. Mister Satan is sent to defeat Boo, but starts to befriend him instead. Meanwhile Goten and Trunks perfect the Fusion techniques, creating “Gotenks”, but he is not yet a match for Boo.
--DB Chapters 478-482 (DBZ 284-288) are set on this day.
[Ref: Daizenshuu 7 has everything up to and including Boo’s death all happen on this day, but in Chapter 478 the narrator says 1 full day passes between Goku reuniting with Gohan and Gohan breaking the Z Sword, after which Kaioshin spends 25 hours powering Gohan up, so it must be 2 days between the tournament and Boo’s death. The transition point between the second day and the third one isn’t clear, however.]

--DBZ Movie 11: Mister Satan’s old rival Baron Jager Batta has used bio-technology to create a series of Bio-Warriors, including a clone of Broli. Trunks, Goten, No.18, and Kuririn fight this Bio-Broli, which is ultimately destroyed by sea water.
[Ref: While calling it a “movie-only story”, Daizenshuu 6 places this between the end of the 25th Tenkaichi Budokai (May 7) and the showdown with Boo (May 9). I’ve arbitrarily set it at the midpoint between these dates.]

--DBZ Movie 12: In the afterlife the Spirits Laundering Machine, which cleanses the evil from the souls bound for Hell, explodes, transforming a nearby Oni into a monster called “Janenba”. Goku and Vegeta use the Fusion technique to become “Gogeta” and destroy it.
[Ref: Daizenshuu 6 places this between Goku transforming into a Super Saiyan 3 (May 7) and the climax of the battle with Boo (May 9). Once again, I’ve arbitrarily placed it on the midpoint between those two dates.

May 9th, Age 774
Boo is defeated
--Boo adopts a pet dog, and at Satan’s suggestion vows to never kill or destroy again. But evil humans shoot Boo’s dog, and a new, evil Boo is born. This evil Boo wipes out the remaining Earthlings and battles Gotenks, who he absorbs to gain an edge over the powered-up Gohan. Meanwhile Goku is resurrected when the Elder Kaioshin gives him his life, and also receives the Elder Kaioshin’s pair of Potara earrings. Goku heads to Earth to merge with Gohan and defeat Boo, but when Gotenks splits up inside Boo he absorbs Gohan next. Goku instead uses the Potara to merge with Vegeta (returned to the living world thanks to Uranai Baba), forming “Vegetto”. Vegetto outclasses Boo but allows himself to be purposefully absorbed so that he can rescue the others inside Boo.
--The bad air inside Boo splits Vegetto up again, and Goku and Vegeta undo all Boo’s absorptions, reverting him to his pure, childlike form, which destroys Earth. Boo pursues Goku and Vegeta to the Kaioshin Realm for a final showdown. The Namekian Dragon Balls are used to restore Earth and all those who have died, including Vegeta and the Elder Kaioshin. With Satan’s help Goku creates a Super Genki-Dama from the energy of all the people of Earth, annihilating the evil Boo. The good portion of Majin Boo survives though, and goes to live on Earth with Mister Satan, eventually changing his name to “Mister Boo”.
--DB Chapters 482-517 (DBZ 288-323) are set on this day.
[Ref: In Chapter 479 Elder Kaioshin says his power-up takes a total of 25 hours, so Gohan’s fight with Boo and everything afterwards must be a day later than the Z Sword getting broken, which is itself established in Chapter 478 as a day after Goku returns to the afterlife. I think the switchover is Chapter 483, as Satan reads to Boo from A Dog of Flanders. Daizenshuu 7 however places everything after Goku returns to the afterlife into one day.]

Later in Age 774
--Due to Goku’s desire to have a rematch with the evil Boo, Enma Daio pulls some strings on his behalf and has Boo reincarnated as an Earthling. This reincarnation, “Oob”, is born in a poor village on South Island. His parents go on to have four more children.
[Ref: Oob’s birth year is from his Daizenshuu 7 bio. I don’t know how this whole reincarnation thing works, but I’d assume Oob could only have been born after Boo’s death, although it’s interesting to wonder if Oob had to have also been conceived afterward as well. Actually, let’s not get into that debate. Anyway, Goku explains Boo’s reincarnation in Chapter 519. Also in Chapter 519, Oob is said to be 10 years old, and the oldest of 5 siblings.]

June~September, Age 774

--DBZ Movie 13: The wizard Hoi tricks Goku and co. into using the Dragon Balls to unseal Tapion from his music box prison. In this way Hoi eventually reunites the upper half of the phantom Majin Hildegarn sealed inside Tapion with the lower half that was sealed within Tapion’s brother Minoshia. The completed Hildegarn is destroyed by Super Saiyan 3 Goku.
[Ref: Daizenshuu 6 places this after the conclusion of the battle with Boo. I’ve arbitrarily decided it’s before people’s memories of Boo are erased, and placed it in this range. This movie does mark the first appearance of Videl as “Great Saiyaman No.2”, while the filler in DBZ Episode 287 which is set shortly after people’s memories of Boo are erased features her second appearance, so this makes a certain sense. The movie takes place over at least 4 days. On Day 1, Hoi meets Gohan and (assuming they gather the DBs in one day) Shen Long unseals Tapion. As the sun sets Trunks goes to feed Tapion for the first time, and at night he feeds him some more, saying he’ll come again tomorrow. Hildegarn’s lower half attacks the city seemingly that same night, while the upper half smashes up the warehouse Tapion is sleeping in. On Day 2 Trunks discovers the damage Hildegarn caused to the warehouse. That night Hoi attacks Tapion, who then stays at Capsule Corporation, where he tells Bulma his backstory. On Day 3 Bulma finishes Tapion’s “bedroom”, and that night Hildegarn’s lower half eats lots of people. On Day 4 Hildegarn’s two halves reunite and Goku eventually saves the day.]

September 7th, Age 774
--The people of Earth’s memories of Majin Boo’s rampage are erased by Shen Long, allowing the good Boo to live on Earth in peace. People only remember that Mister Satan had saved them from “something”, and he becomes an even bigger hero.
--DB Chapter 517 (DBZ 323) is partially set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 469 Dende says they’ll be able to use the remaining 2 wishes in 4 months, since they only used 1 of the 3 wishes. That was on May 7th, so four months later gets you September 7th. However, Chapter 517 says this wish occurs “half a year later”, which would put this in November. The JSAT Special and DBO seem to imply that people remember Boo.]

September~December, Age 774
--DBZ Episode 287: Now free to wander around in public, the good Majin Boo has various adventures.
[Ref: The episode seems not long after people’s memories of Boo are erased.]

--DBZ Episode 288: Bulma holds a big get-together at Capsule Corporation, while Goku watches over some hatching dinosaur eggs and ends up late.
[Ref: The episode seems not too long after the last one, but nothing is specified. I’m sticking it here.]

AGE 775
--DBGT: In space, Doctor Mu recruits the swindler Doltaki as one of his subordinates, entrusting him with the powerful Machine Mutant Llod. Doltaki uses his skills as a swindler to create the scam religion Llodism, and begins gathering energy from its adherents. Mu puts this energy towards Baby’s further development.
[Ref: Date from GT Perfect File Vol.1. This is only 14 years prior to GT, though in one episode Llodism is said to be 20 years old.]

AGE 776
--JSAT Special: On Earth, Mister Satan has a hotel built in his honor, and invites Goku’s friends and family to celebrate. Vegeta’s younger brother Tarble comes to Earth, pursued by Freeza’s former henchmen Abo and Kado. Unimpressed, Goku lets Goten and Trunks take on the evil-doers, but eventually steps in when they merge into “Aka”. Satan’s hotel is destroyed in the battle, but Goku and co. promise to help him rebuild it.
[Ref: The special sets this as 2 years after Boo’s defeat.]

AGE 777
--The luckiest year ever.
[Ref: Well, obviously.]

AGE 778
--By this year, Capsule Corporation controls 48% of the world vehicle market.
[Ref: This is explained in Daizenshuu 7’s section on Capsule Corporation, pages 202-203.]

--Bulma and Vegeta’s daughter Bra is born in this year.
[Ref: Her Daizenshuu 7 bio gives this as her birth year. However, the timelines in Daizenshuu 7 and GT Perfect File Vol.1 give her birth year as Age 780. Lots of people say Bra looks too old to be 9 in GT, and while I don’t necessarily agree, I’m going with this earlier birth year for the hell of it. This makes her 11 in GT, still pretty young.]

--Son Gohan and Videl are probably married around this time.
[Ref: The series and guidebooks never give a date, but the JSAT Special shows them as still not married, while Daizenshuu 7 says their daughter Pan is born in 779. Assuming they don’t have Pan out of wedlock, this puts their marriage sometime between 776-778. I’m estimating it as 778 specifically due to the well-established trend of DB couples having children immediately after getting married.]

May 7th, Age 778
The 26th Tenkaichi Budokai
--Mister Boo uses his magic to rig the tournament match-ups so that he fights all the strong challengers, then in the finals he throws his fight against Mister Satan. Accordingly, Mister Satan is champion once again, and Mister Boo is runner-up.
[Ref: Date from Daizenshuu 7. In Chapter 518-519 we learn that a couple other TBs were held in the 10 year period between Boo’s defeat and when Goku meets Oob, but it isn’t specified how many such tournaments there were or just when they took place. Daizenshuu 4 and later guidebooks establish the TB where Goku meets Oob as the 28th, placing two extra tournaments between the main part of the Boo arc and the end of the series. Daizenshuu 7 puts four years between the 25th and 26th TB, three years between the 26th and 27th TB, and another three years between the 27th and 28th TB, which seems a reasonable way to space them out. The details about Satan and Boo rigging the tournament is from Chapter 518.]

AGE 779
--Son Gohan and Videl’s daughter Pan is born in this year.
[Ref: Date from Daizenshuu 7. The ages given for her in DBO are also based on her being born this year. In Chapter 519 though, the tournament announcer says she’s 4 years old, though the year is 784, when she should turn 5. Presumably her birthday is sometime later in the year than May.]

--Bulma holds a get-together, but Goku is busy training and doesn’t come.
[Ref: Mentioned in Chapter 518 as 5 years ago.]

--DBO: Lunch makes the news somehow.
[Ref: A news item from this year featuring her is briefly glimpsed in a history book shown in one of the DBO trailers.]

[Herms]

AGE 780 (#780)
Timelines II, III:

--By this time Gohan had taken Trunks (now 14) on as a pupil. They train together to fight the androids, but Gohan is eventually killed fighting them.
[Ref: Trunks explains this in Chapter 335, and more details are shown in Trunks: the Story. The anime Trunks TV Special has a slightly different take on these events. The year number is from Daizenshuu 7’s alternate timeline explanation page. In Chapter 335 Trunks says Gohan died 4 years ago (before his first trip to the past), while in Trunks: the Story it’s said to be 3 years.]

--DBO: Pilaf attempts to conquer the world, only to fail yet again.
[Ref: A news item from this year featuring him is briefly glimpsed in a history book shown in one of the DBO trailers. I’m assuming he tried and failed to take over the world, because what else does he ever do?]

AGE 781
May 7th, Age 781
The 27th Tenkaichi Budokai
--Mo Kekko loses to Mister Boo in the semi-finals. The champion is Mister Satan yet again, and Mister Boo is runner-up.
[Ref: Date from Daizenshuu 7. Chapter 519 mentions Mo Kekko losing to Boo.]

AGE 784
--By this year, Human-type Earthlings make up 75% of the planet’s population, while Animal-types make up 17%, Monster-types 7%, and hybrids with other races (such as aliens) make up 1%. The proportion of Animal and Monster-types is gradually decreasing. The reason is that those two types of Earthlings are themselves comprised of a great diversity of sub-types, and it is difficult for them to produce offspring with those not of their own sub-type (ie, dog-people have trouble mating with anyone besides other dog-people).
[Ref: A pie chart showing the proportion of Earthling types is featured in Daizenshuu 7’s race section and dated to this year. The explanation of decreasing Animal/Monster-types is from there too.]

--Now the strongest person in his village, Oob decides to enter the next Tenkaichi Budokai in order to use the prize money to buy food for his family.
[Ref: As explained in Chapters 518-519.]

May 6th, Age 784
--In the morning, Oob arrives at the Tenkaichi Budokai grounds. Trunks visits the Son household, where Goku announces his desire to enter the Tenkaichi Budokai the next day, sensing that the evil Boo’s reincarnation will be participating. Vegeta decides to enter too, and the fathers have Goten, Trunks, and Pan enter as well.
--DB Chapter 517-518 (DBZ 323-324) are set on this day.
[Ref: Chapter 517 establishes that 10 years have passed since the battle with Boo. In Chapter 518 Vegeta says the tournament is the next day, and Goku says Oob arrived that morning.]

May 7th, Age 784 (#28T)
The 28th Tenkaichi Budokai
--By this time, the youth division has been abolished, while Mister Satan is set up as a “Super Champion” who only has to compete in the tournament finals. Pan defeats Mo Kekko in Match 1, while Goku faces Oob in Match 2. Goku cuts off the fight midway, deciding that Oob needs more training before he can give him a proper fight. The two set off to train, with Goku passing his Kinto-Un on to Oob.
--DB Chapters 518-519 (DBZ 324-325) are set on this day.
[Ref: Date from Daizenshuu 7. Chapter 518 sets this as 10 years after the battle with Boo. Details on youth division and Super Champion are from Chapter 518. Goku giving Oob Kinto-Un is from the revised Kanzenban version of Chapter 519.]

--DBO: Mister Satan is champion of the 28th Tenkaichi Budokai, and Mister Boo is runner-up.
[Ref: A history book in one of the game’s trailers shows this result for the tournament, though it dates it to 778 rather than 784. Other dates given in the game are consistent with the Daizenshuu 7 timeline, so this is presumably just an error.]

--DBZ Episode 291: The tournament is put on hold, but Pan beats Goten in a sparring match.
[Ref: The manga doesn’t specify what happens after Goku and Oob leave, but the anime shows the tournament put on hold and the audience leave.]

Timelines II, III:

--Bulma completes work on a time machine, which she hopes to use to save Earth from the androids. Though changing the past will merely create an alternate timeline and have no direct effect on their own world, Bulma hopes that by studying the androids in the past they may discover some weakness in them, or possibly they could bring Goku from the past into their own timeline and have him defeat the androids for them. If nothing else, Bulma wishes for there to be at least one peaceful timeline where the androids do not exist. She sends Trunks to Age 764, shortly before Goku returns to Earth from Namek, to warn him about the androids and give him medicine to cure the heart disease that led to his death in their own timeline. After Trunks returns, they begin waiting 8 months for the time machine to charge up enough energy for another round trip.
[Ref: Bulma’s motives are explained in Chapter 357 and Trunks: the Story. The year number I’ve used is from Daizenshuu 7’s alternate timeline explanation page. In Chapter 334 Trunks says he came from roughly 20 years in the future, but in Trunks: the Story Bulma says he’ll go 17 years into the past. Meanwhile the Trunks TV Special has Bulma tell him to go 20 years into the past. The 8 months it takes the time machine to charge is from Trunks: the Story, though Chapter 419 seems to imply it needs 3 years to charge rather than 8 months. I’ve ignored this.]

AGE 785
Timeline III:

--Now that the time machine has stored enough energy for another round trip, Trunks departs for Age 767 to help Goku and co. confront the androids. After returning to his own timeline, Trunks manages to defeat the androids there on his own in some way.
[Ref: Year number is from Daizenshuu 7’s alternate timeline explanation page. Chapter 358 shows Cell as coming from 788, which Trunks says is 3 years further into the future than he himself came. Presumably during the 8 month charge time the year has changed from 784 to 785. In Chapter 363 Cell simply assumes the androids in his timeline were destroyed by Trunks. The Daizenshuu 7 alternate timeline explanation says that the Trunks in Cell’s timeline had defeated the androids using their shutdown controller, which he found in the past, while DB Forever simply says he defeated them “in some way”. Apparently there are problems with the shutdown controller scenario, so I’m erring on the side of vagueness.]

Timeline II:

--Now that the time machine has stored enough energy for another round trip, Trunks departs for Age 767 to help Goku and co. confront the androids. After returning to his own timeline, Trunks uses the strength he gained training in the Room of Spirit and Time to easily defeat the androids there. Having learned about Cell in the past, Trunks begins waiting three years for Cell to show himself.
--DB Chapter 419 (DBZ 225) is partially set on this day.
[Ref: Déjà vu all over again: year number is from Daizenshuu 7’s alternate timeline explanation page. Chapter 358 shows Cell as coming from 788, which Trunks says is 3 years further into the future than he himself came. Presumably during the 8 month charge time the year has changed from 784 to 785.]

AGE 786
Timeline III, perhaps II:

—Cell completes his 24 years of development. However, the computer informs him that in order to reach his perfect form, he must absorb two specific life-forms: Androids No.17 and No.18. Cell begins looking for these androids.
[Ref: The date is from Cell’s Daizenshuu 7 bio. Cell mentions his 24 years of development in Chapter 363, though counting from that year (767) would mean Cell only finishes development in 791, despite the fact that he’s supposed to have come from 788. It’s all a bit knotty, but basically Daizenshuu 7 tries to fix this by counting the 24 years as starting in 762, when the first (known) cells for Cell are collected. This leaves a two year gap between when his development completes and when he uses Trunks’ time machine, but I guess he just wandered around looking for 17+18 during that time. If Cell was in the lab for a year after Trunks returned from his second trip to the past, then it’s not clear why Trunks in Timeline II waited 3 years for Cell to show himself, rather than just going to destroy Cell in Gero’s laboratory right away. Well, whatever.]

AGE 787
May 7th, Age 787 (#DBO1)
The 29th Tenkaichi Budokai
--DBO: Once again, Mister Satan is champion and Mister Boo is runner-up. Mister Satan’s runaway success raises interest in the martial arts, and the Tenkaichi Budokai grows in popularity, making Mister Satan and Mister Boo into (even bigger) stars.
--DBGT: Pan enters this tournament too.
[Ref: Date from the DBO timeline. In GT Episode 34 Pan refers to the 28th TB as the “first time” she entered, and since the 30th TB (probably) hadn’t occurred yet, presumably she entered this one as well.]

DBO: Dende resolves to seal the Dragon Balls.
--As the Elder Kaioshin said, the Dragon Balls go against the natural order, and with the world now at peace Dende is worried that their presence may backfire and lead to disaster.
[Ref: From the DBO timeline.]

AGE 788
Timeline III:

–Unable to find Androids No.17 and No.18, Cell finally concludes that Trunks must have destroyed them. Learning of Trunks’ time machine, he kills Trunks and uses the time machine to travel to Age 763, to find the androids in the past. To fit inside the time machine, Cell reverts into an egg.
[Ref: Cell explains this in Chapter 363. In Chapter 358 Cell is said to have come from Age 788, the only specific year actually stated in the original series. The specific year Cell travels to is from Daizenshuu 7.]

Timeline II:

--In the three years since the androids’ destruction, reconstruction of Earth society has advanced considerably. Unable to find Androids No.17 and No.18, Cell learns of Trunks’ time machine and attempts to kill Trunks and steal it. However, thanks to his trip into the past Trunks knows Cell is coming, and uses the strength he gained training in the Room of Spirit and Time to easily destroy him.
--DB Chapters 419-420 (DBZ 225-226) are set on this day.
[Ref: These events are shown in the above-mentioned chapters. The date is from Daizenshuu 7’s alternate timeline explanation, and is based on Chapter 358 where Cell is said to have come from Age 788.]

--DBO: Sometime afterwards, Trunks becomes a “Time Patroller” and devotes himself to defeating those who try to interfere with the past.
[Ref: The game depicts Trunks in this way. I’m assuming it’s the same Trunks from this timeline, but it might not be.]

AGE 789

January 7th, Age 789 (#GT1)
--DBGT Episode 1: Oob’s training under Goku ends. Soon after, Pilaf breaks into the Heavenly Realm and obtains the Ultimate Dragon Balls, but accidentally wishes Goku to be a child. The Ultimate Dragon Balls scatter across the universe, and North Kaio reveals that the Earth will explode if they aren’t gathered and properly sealed away again within a year.
[Ref: The year is from GT Perfect File Vol.1, but the exact date here is my own. After Goku’s turned into a child, it’s at least one day before he, Trunks, and Pan take off into space. In Episode 2, someone says that the spaceship will be ready by as early as tomorrow. It’s unclear though how long the start of Episode 2 is from Episode 1. Creating a spaceship in just a day seems pretty crazy, though this is Dragon Ball. GT Perfect File Vol.1 establishes that both Pilaf’s wish and the final fight with Baby are in 789, while Episode 40 says there’s two weeks between Baby’s death and Earth exploding. Earth exploding is supposed to be a year after Pilaf’s wish, meaning it must be in 790, so the wish must be very early in 789 while the Baby battle must be very late in the year.]

January 13th, Age 789
--DBGT Episode 2: Goku is “kidnapped” by criminals seeking ransom money from Capsule Corporation. Meanwhile, work on the spaceship nears completion.
[Ref: Date my own. After Baby is defeated, they say it’s been almost a year since Pilaf’s wish, and that they have two weeks before the Earth explodes. Earlier, right after Goku and co. came back to Earth, we’d been told a total of 11 months had gone by since Goku and co. left, leaving a missing half a month. To help solve this I’m inserting a week between GT Episodes 1 and 2, meaning it takes about a week for them to build the spaceship.]

January 14th, Age 789
--DBGT Episode 2: The spaceship is completed, and Goku, Pan, and Trunks take off into space. However, at this time a piece from the rocket guidance system breaks off.
[Ref: Date my own, reasoning given above. GT Perfect File Vol.1 places this 9 months before Baby reaches Earth, while Episode 28 has 2 more months between that and the group returning to Earth, and after Baby’s defeat there are 2 weeks before Earth explodes.]

January 21st, Age 789
--DBGT Episode 3: Goku and co. crash on Planet Imegga, and spend the night in a local hotel.
[Ref: Once they take off, it’s said to be a week before they crash on Planet Imegga according to a scene on Earth with Chi-Chi and Bulma. So this is a week after my personal date for their departure. They then spend four days on Imegga: after crashing, they spend the night at a hotel, have their spaceship stolen the next day, steal it back that night, find themselves wanted criminals the next day, defeat Don Kia and his men that night, then leave the next day.]

January 22nd, Age 789
--DBGT Episodes 3-4: Goku and co. meet the robot Gill and have their spaceship stolen. They steal it back during the night, and Goku encounters Redgic, the powerful bodyguard of local overlord Don Kia. They learn Don Kia uses exorbitant rental contracts to oppress the people of Imegga.
[Ref: As explained above, this is the next day.]

January 23rd, Age 789
--DBGT Episodes 4-5: Thanks to Don Kia Goku and co. are now wanted by Imegga’s police, and at night they confront Don Kia. Goku defeats Redgic and Don Kia surrenders.
[Ref: As explained above, this is the next day.]

January 24th, Age 789
--DBGT Episode 5: Goku and co. return the rental contracts to the people of Imegga, and leave the planet.
[Ref: As explained above, this is the next day.]

March 13th, Age 789
--DBGT Episode 6: Goku and co. find the Ultimate 4-Star Ball on Planet Mommath.
[Ref: Date my own; it’s simply the date GT Episode 6 was originally broadcast, which works well within this time-frame. The events on Planet Mommath seem to be one single day. It’s unknown how long it takes them to get there from Imegga, or how long it takes them to get from Mommath to Calvo.]

April 23rd, Age 789
--DBGT Episode 7: Goku and co. arrive on Planet Calvo, and promise to take care of the catfish monster Zunama in exchange for the Ultimate 6-Star Ball.
[Ref: The exact date is again my own. They spend two days on Planet Calvo, spending the night there to get Trunks into his bride disguise, then confront Zunama the next day. For the date, to spread things out a little I used the original airdate for Episode 24 (April 24th) as the date the group reaches Planet Bihe, then backtracked from there.]

April 24th, Age 789
--DBGT Episodes 7-14: Goku and co. defeat Zunama, but the Ultimate 6-Star Ball is stolen by the Para-Para Brothers, Doltaki’s underlings. Goku and co. defeat the Para-Para Brothers on Planet Bihe, but Pan and Gill are accidentally sent to Planet Llod. Goku and Trunks follow, and together with Pan they defeat the Machine Mutant Llod.
[Ref: Exact date my own. Bonpara steals their Dragon Ball immediately after Zunama’s defeat, then they go after them and get lured into Planet Bihe. The Para-Para Brothers are able to go to Planet Llod and back without Goku and co. realizing they’re gone, so apparently the trip doesn’t take very long. So altogether the Bihe and Llod stuff seems to all be a single day. For the date I’ve used the original air date of Episode 24, as explained above.]

June 11th-12th, Age 789
--DBGT Episode 15: Goku and co. find the Ultimate 5-Star Ball on Planet Rudeze.
[Ref: Exact date my own. GT Episode 15 has these events take place over two days. For the date I’ve used the original airdate for Episode 15, June 12th, and backtracked from their for the first day, just so I could have June 11th (King Kamehameha Day) on the timeline. I am nothing if not scientific.]

August 21-22nd, Age 789
--DBGT Episodes 16-22: Goku and co. visit Planet M-2, home base of Doctor Mu’s Machine Mutant Army. As part of his plan to learn what Mu is up to, Trunks is intentionally turned to metal by General Rild, and shipped to the planet where Mu's laboratory is located. He is freed by Gill, and together with Goku and Pan they discover Baby, the parasitic Machine Mutant which Mu had been raising. They seemingly destroy Baby, but he escapes.
[Ref: Exact date my own. GT Episodes 16-22 take place over two days. According to GT Perfect File Vol.1, Goku and co. encounter Baby “several months” after going into space. For the date I’ve used August 21st as the start, the original air date of Episode 21, when Goku and co. first fight Baby.]

August 28th, Age 789
--DBGT Episodes 23-24: Goku and co. find the Ultimate 1-Star Ball in a derelict spaceship. They rescue the ship's only survivor and take him to Planet Pital, where it turns out the boy has been taken over by Baby, but they manage to drive Baby away again.
[Ref: Exact date my own. It’s unclear how long it is from their first encounter with Baby to rescuing the boy on the derelict ship and going to Planet Pital. The show kind of implies they reach the derelict ship immediately after departing from M-2, but Baby must have needed some time to get ahead of them and take out that ship. To space things out, I’ve used the original airdate of Episode 23, where the derelict spaceship appears.]

October 16th, Age 789
--DBGT Episodes 25-27: Baby arrives on Earth, and takes control of Goten, Gohan, and Vegeta. Baby then begins laying eggs inside all Earthlings, taking over the entire planet. At around the same time, Goku and co. find the Ultimate 7-Star Ball on a planet inhabited by giant tigers.
[Ref: Exact date my own. GT Episodes 25 has Bulma and Chi-Chi say that it’s been 9 months since Goku and co. left. Bizarrely, they then add that they’ve got 4 months left until the Earth explodes. So, uh, are years 13 months long in the Dragon World? Anyway, this is roughly 9 months after my date for Goku and co.’s departure. Baby then shows up, fights Goten and Gohan, and manages to take over Vegeta by that night, so these three episodes are all one day. What’s interesting is that the scenes on Earth are juxtaposed with scenes of Goku and co. finding the three remaining Dragon Balls. I’d chock this up to artistic license of whatever, since presumably they didn’t get all three in the same day (but again, this is DB).]

October 30th, Age 789
--DBGT Episode 26: Goku and co. discover the Ultimate 3-Star Ball on a planet inhabited by dinosaurs.
[Ref: Exact date my own. It’s the airdate for the episode that shows them finding the ball, though the show depicts this as the same time as Baby taking over Goten/Gohan/Vegeta. To space things out I’ve decided to ignore this.]

November 6th, Age 789
--DBGT Episode 27: Goku and co. discover the final Dragon Ball, the Ultimate 2-Star Ball on a planet of ice. They then begin to return to Earth.
[Ref: Exact date my own. It’s the air date of the episode that shows them finding the ball. The reasoning is the same as above.]

December 18th, Age 789
--DBGT Episodes 28-30: Goku and co. arrive back on Earth, only to find the entire planet under Baby's control. Goku fights Baby, but is defeated. Baby then uses the Ultimate Dragon Balls before they can be properly sealed away again, wishing to create a planet identical to the old Planet Tsufru (aka Planet Plant, aka Planet Vegeta), which he likewise calls Planet Tsufru. Immigration of chosen Earthlings to Planet Tsufru then begins.
[Ref: Exact date my own. According to Mister Satan in Episode 28, it’s been 2 months since things started getting weird on Earth, so it’s that long between Baby arriving on Earth and Goku and co. returning. This is therefore that long after my date for Baby’s arrival. This also means that it’s been a total of 11 months since Goku and co. left Earth. It seems Baby defeats Goku the same day Goku and co. arrive back, but after that the timeline gets hazy. We never see any night anywhere from Baby’s defeat of Goku to Baby being destroyed by SSJ4 Goku, but it seems pretty hard to believe that everything from Goku and co. returning from space to Baby’s defeat was all one day, especially with the immigration of all those people to Planet Tsufru, but once again, this is DB.]

December 19th-23rd, Age 789
--DBGT Episodes 30-31: After being rescued from Baby’s attack by East Kaioshin, Goku falls into Sugoroku Space, an alternate dimension. He eventually manages to escape, and begins training in the Kaioshin Realm to defeat Baby. Meanwhile, select Earthlings continue to immigrate to Planet Tsufru.
[Ref: Exact date my own. As mentioned, there’s no explicit transitions between days any time after Goku and co. return to Earth. However, after Baby is defeated, Dende says it’s been almost a year now since Pilaf’s wish, and that they have two weeks before the Earth explodes. Earlier, right after Goku and co. came back, we’d been told a total of 11 months had gone by since Goku and co. left. To help fill up the half month this leaves unaccounted for, I’m placing about a week between Goku’s initial defeat and the final fight with Baby.]

December 24th, Age 789
--DBGT Episodes 32-39: Oob and Mister Boo merge to confront Baby, but ultimately lose. His training in the Kaioshin Realm causes Goku’s tail to regrow, and he then heads to Planet Tsufru to likewise confront Baby, though without much better results. But seeing the Earth causes him to transforms into a Golden Oozaru (a state where he’s simultaneously Oozaru and Super Saiyan) and go on a mindless rampage. With Pan’s help he recovers his senses, further transforming into a human-sized form Elder Kaioshin dubs “Super Saiyan 4”. In this state Goku ultimately drives Baby from Vegeta's body and knocks him into the sun, killing him. Baby's eggs are then purged from everyone's brains using the Super God Water.
[Ref: Exact date my own. But as explained above, if this is still 789 (as say the GT Perfect File Vol.1) and it’s only two weeks before the Earth’s destruction (as says episode 40), and event which must occur in 790 (per episode 1), then this must be very late in 789. For the exact date I’ve chosen December 24th, to make it the anniversary of Goku’s initial Super Saiyan transformation back in the Freeza arc.]

December 25th, Age 789
--DBGT Episode 40: Contact between Earth and Planet Tsufru is established. With the Earth to explode in two weeks, evacuation of all Earthlings to Planet Tsufru begins.
[Ref: Exact date my own. Episode 40 has this as the next day, and 2 weeks before the Earth explodes.]

AGE 790 (#790)
May 7th, Age 790
DBO: The 30th Tenkaichi Budokai
--Mister Satan is champion, and Mister Boo is runner-up. As always, the pair continues to rig the tournament.
[Ref: From the DBO timeline.]

DBO: Mister Boo divides himself up, creating a female Boo.
--Mister Boo had grown envious of the intimacy of human lovers. In Mister Satan’s study, he reads “Bob and Margaret’s Forbidden Games”, a classic of erotic fiction. It influences him to create his ideal female Boo.
[Ref: From the DBO timeline.]

January 7th (#GT2)
--DBGT Episode 40: The Earth explodes due to the influence of the Ultimate Dragon Balls. Piccolo willingly stays behind to prevent the same thing happening again, and as he dies the Ultimate Dragon Balls become ordinary stones. The Earth is then restored with the Namekian Dragon Balls.
[Ref: The year number is based off this being one year after Pilaf’s wish, which GT Perfect File Vol.1 has in 789. The exact date is a year after my personal date for Pilaf’s wish. I’m assuming this “year” time limit goes right down to the second, so that if Pilaf made the wish at 9:00 AM (for instance) on January 7th 789, then the Earth would explode at 8:59 AM on January 7th 790.]

May 7th, Age 790
--DBGT Episode 41: The 30th Tenkaichi Budokai is held. The champion of the youth division is Magure, and the runner-up is Son Goku. The adult division champion is Mister Satan, and the runner-up is Papayaman.
[Ref: May 7th is the eternal date of the TB. For the year, I’m assuming it’s the same year as the Earth’s explosion. It’s another instance where it’s unclear how much time has gone by. However, it does seem that a good deal of time has passed since Baby’s defeat, as the Earth is back to normal. Still, everyone looks exactly the same as they did before, so it doesn’t seem to be a number of years. Using May 7th gives 4-5 months since the Earth exploding. I think that’s a decent time-frame for everything on Earth to settle back down to normal. The episode doesn’t specify what number TB it is. During the Golden Oozaru Goku episode, Pan referred to the 28th TB as when she “first” entered, implying there’s been at least one more. I’m assuming the TB is back to being every 3 years and that the 29th was in 787 and that this one in 790 is the 30th, which actually fits in with how things are in DBO.]

Sometime in August, Age 790
--DBGT Episodes 42-47: In Hell, Doctor Gero and Doctor Mu team up to create the Machine Mutant/android hybrid “Super No.17”, opening a hole between Earth and Hell. Goku defeats Super No.17 with No.18's help, but Kuririn is killed by No.17, and there are many natural disasters as a result of Hell and Earth having been linked. Goku, Trunks, and Pan set out to gather the (regular) Dragon Balls to restore things to normal.
[Ref: The date is my own. Again, there’s no indication of how long it’s been since the last episode. All the events themselves up to Super No.17’s defeat seem to be a single day. It doesn’t say how long it took Goku and co. to gather the Dragon Balls. The date I’ve used is just backtracking from my dates for the Evil Dragon stuff, which are themselves based mostly off of trying to reference the dates for the original DB search. It’s also a reference to Trunks originally showing up “sometime in August”, back in 764.]

August 22nd, Age 790
--DBGT Episodes 48-50: Goku and co. finish collecting the Dragon Balls. They try to summon Shen Long, but instead cause seven Evil Dragons to appear, as a result of having overused the Dragon Balls during the last 40 years. Goku and Pan defeat Liang Xing Long [2-Star Dragon], then Wu Xing Long [5-Star Dragon] later that day. Liu Xing Long [6-Star Dragon] appears in Bish's seaside village, and begins causing fish to fall from the sky.
[Ref: The date is my own. After they try to make the wish, Goku and Pan go straight to Liang Xing Long and defeat him, then fight Wu Xing Long right after, so episodes 48-50 are all a single day. I wanted to set the final battle with Yi Xing Long on September 9th, the anniversary of Shen Long’s first summoning in the series, so I’m getting these other dates by backtracking from there.]

September 5th, Age 790
--DBGT Episode 51: Due to Liu Xing Long, the fishermen in Bish’s village have now grown lazy. Goku and Pan meet Bish, and defeat Liu Xing Long.
[Ref: The date is my own. Since the fight with Wu Xing Long a lot of time goes by before they fight Liu Xing Long, as enough time has passed for life in Bish’s village to have changed. Bish says his father and the rest have gotten lazy “ever since the princess appeared” and that they go out “every day” to gather all the fish that drop from the sky. So it’s been awhile since the appearance of the Evil Dragons; I’ve set it as about 2 weeks. Episode 51 itself takes place over not more than a day.]

September 7th, Age 790
--DBGT: Episodes 52-53: Goku and Pan defeat Qi Xing Long [7-Star Dragon]. On the Son family’s Mount Paozu home, the water supply has completely stopped.
[Ref: The date is my own. An unidentified amount of time seems to pass between the fight with Liu Xing Long and Qi Xing Long. A scene shows the problems on Mount Paozu, implying it’s been some time since the Evil Dragon business began. Goku and Pan fight Qi Xing Long over less than a day.]

September 9th, Age 790
--DBGT Episodes 54-64: Goku battles the brothers Si Xing Long [4-Star Dragon] and San Xing Long [3-Star Dragon]. The Evil Dragon’s leader Yi Xing Long [1-Star Dragon] then appears, and overwhelms Goku after absorbing the power of the other Evil Dragons. With Bulma's help, Vegeta finally becomes a Super Saiyan 4, and he and Goku use the Fusion technique to become Super Saiyan 4 Gogeta. After failing to defeat Super Yi Xing Long as Gogeta, Goku finally destroys him with a Genki-Dama containing energy gathered from throughout the entire universe. After wishing that the Earth be restored to normal, Goku departs with Shen Long for parts unknown.
[Ref: The date is my own, in tribute to the first time Shen Long appears in the series, over 40 years ago. There’s another unknown gap between the fight with Qi Xing Long and the one with Si Xing Long, but from then on everything clearly happens back-to-back, until the flash forward to 100 years later. Technically everything from Episode 51-64 could all be one day, but I’ve broken it up a bit just because I like it better that way.]

[Herms]

AGE 791 (#DBO2)
DBO: A child is born to Mister Boo and Missus Boo (aka “Booby-Booby”). This marks the birth of the Majin race.
--Boo had read the phrase “booby booby” in “Bob and Margaret’s Forbidden Games”. Remembering it, he used it as the name of his wife. Boo breaks off pieces of his own body and forms them into tons of dumpling-like objects. He then fires his Love-Love Beam at these dumplings, creating babies. Afterwards these descendants of Boo form the “Majin” race and gain acceptance throughout the world.
[Ref: From the DBO timeline.]

--From this point onward, nothing more is known about what becomes of Oob or Yamcha.
[Ref: They’re not mentioned in the DBO timeline or the “100 years later” portion of GT. Clearly, nobody cares.]

AGE 793
DBO: Mister Satan announces his retirement from the world of martial arts.
--His official reason for retiring is so that he can “give the next generation a chance.” However, the truth is that after dividing up himself Mister Boo had lost interest in the Tenkaichi Budokai, meaning Satan could no longer rig the tournament.

DBO: Mister Satan begins managing the “Satanic Martial Arts Correspondence Course”.
--As a money-making scheme, Satan begins selling videos as a sort of martial arts correspondence course. These videos are really just overpriced rip-offs (?) that use special effects to make Satan look impressive.
[Ref: From the DBO timeline.]

AGE 794
DBO: The “Satanic Martial Arts Correspondence Course” is restarted as the “Pan Fighting Network”, which features Pan as an instructor.
--Purchasers of the “Satanic Martial Arts Correspondence Course” begin demanding their money back en masse, complaining that the course hasn’t made them any stronger. Disgruntled costumers storm Satan’s house, only to be beaten back by Pan (now 15 years old). Pan’s handling of the situation becomes big news, and so the “Satanic Martial Arts Correspondence Course” is revived with Pan as the instructor. This martial arts course would go on to gain great popularity among the young, who saw it as just another sport.
[Ref: From the DBO timeline.]

AGE 796
DBO: The film “The Legend of Satan” opens, starring Mister Satan.
--Mister Satan ends up being very active as a movie star, appearing in all sorts of movies, including everything from romance films to action flicks. “The Legend of Satan” is a thrilling action movie which uses special effects to depict Mister Satan fighting evildoers with the same kinds of techniques as Goku and co. Though it fares poorly at the box office, it gains a cult following. Influenced by this film, some begin studying Pan’s system of ki manipulation, leading to the birth of the “Martial Artist” class.
[Ref: From the DBO timeline.]

AGE 801 (#800)
DBO: Son Goku vanishes.
--Knowing his end is near, Goku leaves Earth with Vegeta so that the two can finally settle their score. Several years later, astronomers note the explosion of a supernova. Possibly this was an aftereffect of Son Goku and Vegeta’s battle.
[Ref: From the DBO timeline. Goku is 64, Vegeta 69.]

AGE 804
DBO: Gohan begins researching the martial arts of the past, organizing them in “The Science of Ki-Control”
--The death of his father Goku causes Gohan to reflect on the power he wields, and so he immerses himself in research concerning “ki”, the source of that power. The book which results from this research, “The Science of Ki-Control”, secretly gains a following. One of the articles included in it, “Katchin Steel Can be Cut!”, later has a big effect on the birth of the Swordsman class.
[Ref: From the DBO timeline.]

AGE 805
DBO: Trunks and Goten begin practicing “Ki-Control Swordsmanship”
--Influenced by the part of Gohan’s book which went over how Katchin Steel could be cut, a certain number of young warriors develop an interest in swords. When Goten and Trunks learn this, they are seized with the ambition to create a “super cool” school of Swordsmanship. Developing their natural potential through intense training, they form the “Ki-Control Swordsmanship” school.
[Ref: From the DBO timeline.]

AGE 820
DBO: Mister Satan dies. The Earth’s King gives him a state burial.
--The cause of his death…?

DBO: To avenge Freeza, the remnants of his army attack Earth, causing great destruction throughout the world.
--Freeza’s army collapsed after the death of Freeza and his father Cold. However, some of Freeza’s loyal followers who still survived awaited an opportunity to invade Earth and avenge their leader. Because they had not been present when Freeza died, they knew nothing of Goku or Trunks. So when they later investigated the Earth, they assumed that “the Earth’s mightiest man”, Mister Satan, had been the one who killed Freeza and Cold. Knowing they’d be unable to handle anyone strong enough to defeat Freeza, they decided to leave Earth alone so long as Mister Satan was around.

But learning of Mister Satan’s death, they finally make their attack. Having researched Earth ahead of time, Freeza’s remnants attack the planet with aliens impervious both to guns and standard martial arts techniques. The Earth’s Royal Army attempts to fight back but is completely defeated, and any martial artists who take on the invaders are likewise beaten back. Fortunately, they are saved by Trunks and Goten, who put their “Ki-Control Swordsmanship” fighting style into practice. It’s from this event that the “Swordsman” class is born.

DBO: West City becomes a capsule city
--Freeza’s remnants somehow learn that Trunks was Freeza’s real killer, and his hometown of West City becomes their next target. Realizing the danger, Bulma works out a way to store the entire city inside capsules for safekeeping. At this time, the Majins, having lost their homes throughout the world, all gather from far and wide to protect West City. Even after the war, some of them continue to live in West City, and develop their own unique culture.

DBO: With the Earth in crisis, the heroes of the past gather at Kame-sennin’s place and defeat Freeza’s remnants.
--In the end, Freeza’s remnants are defeated by Tenshinhan (aged 87), Kuririn (84), Gohan (63), Trunks (54), Goten (53), and Pan (41), and the other heroes of the past. Prior to this they had all hid themselves and tried not to attract public attention, but as a result of this battle their ki-control style of martial arts becomes a global topic of discussion, and interest in ki grows.
[Ref: All of this is from the DBO timeline.]

AGE 821
DBO: Having helped defeat Freeza’s remnants, Kuririn creates the New Turtle School.
--With there now being much interest in ki-based martial arts, as outlined in Gohan’s “The Science of Ki-Control”, people begin asking Kame-sennin to start teaching martial arts again. But Kame-sennin refuses, citing his age, and has Kuririn and Tenshinhan take his place. To answer the question of “what can Earthling warriors do?” the two of them create the “New Turtle School” and “New Crane School”.

[Ref: Still from the DBO timeline.]

AGE 825
DBO: The theme park “Booby World” opens in South City. The majority of the staff consists of Majins.
--Booby World’s owner is the rich, kindhearted Mister Non. He was the blind boy who Majin Boo healed long ago, and he then went on to work hard and amass a large fortune. Mister Non always wanted to repay Boo no matter what, but Boo was a big star and always busy at the Tenkaichi Budokai, so he never got the opportunity. Satan’s death and the invasion of Freeza’s remnants had left the people of Earth with heavy hearts, so to put smiles back on their faces Non decides to build a huge theme park. Just like Boo had helped him in the past, now it is his turn to help everyone else out. He therefore commissions Minister Boo, one of Boo’s children, to produce the theme park, desiring that the Majins use their powers to bring people joy. Progress on Booby World continues, with “fun” and “tasty” as the park’s main themes, and so the park grounds are divided up into the “Fun Zone” and “Tasty Zone”. Special technology is developed for each section, and many Majins are hired as staff.
[Ref: From the DBO timeline.]

AGE 826
--DBO: Yajirobe descends Karin Tower and begins cultivating Senzu down on the Earth’s surface.
[Ref: From the DBO timeline.]

AGE 834
DBO: Majin Manima dies in battle, protecting people from Freeza’s remnants. His death has a big effect on the Majins.
--Those Majins influenced by Majin Manima become active throughout the world, becoming the ancestors of the new Majin classes: “Ultima”, “Granma”, and “Karma”.
[Ref: From the DBO timeline.]

AGE 849
September 9th, Age 849
--DBGT: After Oolong’s wish for panties, this would have been the earliest point by which Earth’s Dragon Balls could have been safely reused. The Minus Energy from that wish would have been purified by now.
[Ref: In GT Episode 48 the Elder Kaioshin says it takes a century for the Dragon Balls to be safely reused, but Bulma and co. used them countless times over less than 40 years. So this is 100 years after the first wish in the series.]

AGE 851
DBO: New Planet Namek is destroyed by the “pale man” Miira and his army. Great Elder Muri and several hundred other Namekians migrate to Earth.
--Following this, Namekians take up residence on Earth, and Dende warns the Earth’s King about Miira’s army. However, this information is kept secret from the average citizen, as it is feared it would cause a panic. At first the Namekians live in West City. Later most of them move to Polunga Rocks, an area of Yunzabit Highlands altered to look like Namek. Some however remain in West City and develop their own culture.
[Ref: From the DBO timeline. The exact nature of “Polunga Rocks” is from Suzaku/Amaranth Sparrow’s translations.]

AGE 853
DBO: In response to losing their homeland, the Namekians on Earth begin training for self-defense. This results in the creation of the templates for the modern “Demon Realm Warrior”, “Magic Warrior”, “Denden Priest”, and “Poko Priest” classes.
--Some of the monsters which Piccolo Daimao spawned long ago still survive on Earth. These had been raised in secret in a laboratory inside Pilaf’s castle, and had now naturally multiplied in the wild. After the Namekians have settled on Earth for a while, at Great Elder Muri’s suggestion Piccolo and a few other Namekian warriors capture these monsters. In this way, some Dragon Clan Namekians begin researching monsters and become proficient in a fighting style centered around monster-handling. This leads to the birth of the “Poko Priest” class.
[Ref: From the DBO timeline.]

--DBO: Possibly around this time, some of the people of Planet Yardrat also come to Earth.
[Ref: In the game they’re present on Earth in Age 1000. Early English info on the game suggested that their planet was destroyed by Miira and placed its destruction in this year, but this might have been conflating them with the Namekians.]

AGE 890
DBO: The 100th anniversary of the birth of the Majin race.
--In celebration of this centennial, Majin Boo’s house (the Majin Boo Memorial Home) is built.
[Ref: From the DBO timeline. Presumably this refers to a reconstruction of Boo’s original house from the series, kind of like those reconstructions of Abraham Lincoln’s cabin.]

—DBGT Special: Pan, now 111, raises her great-great-grandson “Son Goku Junior”. When Pan falls ill, Goku Junior sets out to find the 4-Star Ball to wish for her health.
[Ref: GT Perfect File Vol.2 refers to the TV Special as 100 years after the main story of GT, which probably ends in 790. I can’t remember if the special itself says this and don’t have the DVD to check though. I’m assuming it and the final scene in GT 64 are set the same year.]

May 7th, Age 890
—DBGT Episode 64: At the Tenkaichi Budokai, Goku Junior fights Vegeta Junior, Bulma and Vegeta’s descendant. During their match, a vision of Goku briefly appears.
[Ref: The episode doesn’t say when the final scene is set, but it’s clearly after the events of the GT TV Special, placing it about 100 years in the future. Goku Junior and Pac look the same as in the special, so presumably it’s not too long afterward, so I’m putting them in the same year. I’m assuming the TB is still held on the same day of the year a century hence. If the 30th TB was in 790, assuming the tournament continues to be held every three years, then this should be 889 and the 63rd tournament. But I’m just going to say there’s been some irregularity in the tournament schedule during this century. I’m tempted to say it was held at less than 3 year intervals at least once and that this is therefore the 64th TB, to match the episode number. The name “Vegeta Junior” is from GT Perfect File Vol.2]

AGE 900 (#900)
--DBO: On Earth, the people of Planet Yardrat are put in charge of Teleportation Machines that allow people to teleport across the globe and store items.
[Ref: Early English info on the game said the Yardratians were perhaps put in charge of developing a time machine, but according to TheDevilsCorpse, who has played the game, they actually run these Teleportation Machines.]

AGE 910
DBO: The 100th anniversary of Booby World.
--Still hiding out on Earth, the remnants of Freeza’s army begin expanding their influence, with Booby Island as their stronghold.
[Ref: From the DBO timeline.]

AGE 920
DBO: The 100th anniversary of Mister Satan’s death; a memorial service is held.
--There is a strong feeling that Mister Satan should be reevaluated, and so “The Legend of Satan” returns to theaters. The latest CGI is used to add on even more action scenes. Around this time, the Satan School breaks off from the “Pan Fighting Network”.
[Ref: From the DBO timeline.]

AGE 940
--DBO: The “Egg of Evil”, born from the evil in the hearts of the Namekians who immigrated to Earth, is first discovered. It is placed under a strong seal for safekeeping.
[Ref: From the DBO timeline.]

AGE 951
--DBO: The 100th anniversary of the Namekians immigrating to Earth.
[Ref: From the DBO timeline.]

AGE 962
DBO: The Capsule Corporation History Museum opens.
--This celebrates the 250th anniversary of Capsule Corporation. A history museum covering all of human history also opens.
[Ref: From the DBO timeline.]

AGE 967~1067
--DBZ Episode 199: The Grand Kaio says he’ll consider training Goku and Paikuhan around this time.
[Ref: In the episode he says he’ll “have another look at them” after another 200~300 years.]

AGE 972
--DBO: The black Namekian “Naraka” is born from the sealed Egg of Evil. He gains many allies, and a civil war erupts among the Namekians.
[Ref: From the DBO timeline. This guy may be named after one of the Buddhist analogs of Hell.]

AGE 974
--DBO: An ethnologist named Doctor Hunbalt releases the Animal Data, a catalog of Earth’s animals.
[Ref: Something about this is featured in the history book shown in one of the game’s trailers. Apparently “Animal Data” is the game’s bestiary.]

AGE 975
--DBO: A system of child-rearing wherein children are separated from their parents for a time to live in the wild becomes national policy.
[Ref: From the DBO timeline. There’s a little more here which, I think, talks about Dende advocating this childrearing policy to the Earth’s King, possibly as a way of finding a “savior”. But I’m far from sure. Anyway, this policy seems like a clear throwback to how Piccolo trained Gohan. Perhaps it’s also to explain why the human characters in the game aren’t at home with their parents?]

AGE 990
--DBO: The 200th anniversary of the Majin race.
[Ref: From the DBO timeline.]

--DBO: Various evil organizations begin to emerge, perhaps as a result of the turmoil surrounding the increasing frequency of monsters in the wild.

--DBO: Dende has “Popo Stones” installed throughout the world.
--At Dende’s request Uranai Baba installs these stones in every region; they allow people to designate the place they return to if they lose consciousness in battle. They then automatically carry people away when they’re on the brink of death.
[Ref: From the DBO timeline.]

--DBO: With the help of a Spirit Medium Robot, Pilaf’s descendant “Paella” resolves to carry on in his ancestor’s footsteps and take over the world.
[Ref: From the DBO timeline. Not quite sure about that “Spirit Medium Robot” thing. One of the early previews for DBO has a history book saying that Paella’s gang attacks “Kinoko Rocks” in Age 988, two years before this.]

AGE 991
--DBO: The Red Pants Army is formed and begins working to restore the animal/human nation.
[Ref: From the DBO timeline. Possibly they may be trying to revive an “Animal-Human nation”, ie a nation of animal people like Oolong. Not really sure what they mean by “revive” though. The Earth’s King in the series is a dog man, but it’s not like his kingdom was exclusively animal people. Perhaps they’re xenophobic against all the Majins and Namekians now living on Earth?]

DBO: The Tenkaichi Budokai becomes more and more popular.
--Due to increasing interest in the martial arts, the Tenkaichi Budokai continues into the present era. In order to allow more young warriors to participate, the current tournament is divided up into “youth” and “adult” divisions once more, and there are both “single battles” and “team battles”. However, even after the passage of centuries, the basic rules of the tournament haven’t changed, and contestants still lose if they touch anywhere outside the ring.
[Ref: From the DBO timeline.]

AGE 995
--DBO: Showa Long betrays Capsule Corporation and joins Paella’s gang.
[Ref: From the DBO timeline. “Showa Long” is another name from the Korean-to-Japanese translation that I don’t have much confidence in. “Showa” seems vaguely close to “Shu” though, one of Pilaf’s henchmen, so perhaps it’s supposed to be a take-off of that. “Showa Long” might also refer to two separate henchmen.]

AGE 998
--DBO: Miira invades Earth. His mothership lands on Booby Island, and this becomes his base as he invades the past.

--DBO: At Dende’s request, Piccolo investigates the various evil organizations (including Miira’s army) that have appeared throughout the world.

--DBO: Capsule Corporation begins to mass produce the “Hope!” series of robots.
[Ref: The history book in one of the DBO trailers says they start mass producing a robot in this year. I’m told by those who play the game that this probably refers to the “Hope!” robots featured in the game.]

AGE 999
--DBO: Trunks from Timeline II, now a Time Patroller, arrives in this era in his time machine. He warns of Miira and the danger to the universe.
[Ref: From the DBO timeline. I’m assuming the Time Patroller Trunks in the game is from Timeline II (ie the timeline we normally associate with “future Trunks”), but this might not be so.]

--DBO: Piccolo begins his investigation into the unusual circumstances throughout the world. He learns of the Red Pants Army, Freeza’s remnants, Paella's gang, and Miira’s army. Returning from his investigation, Piccolo informs Dende of the threat Miira poses to the Earth. At the same time, he realizes that at present Earth has no warriors capable of opposing this threat.

DBO: Hoping that a savior will appear among the Earthlings, Dende revives the Dragon Balls.
--Dende creates multiple sets of Dragon Balls, hoping that by fighting over them, young warriors will refine their techniques and character. The presence of multiple sets allows for warriors of diverse skill levels to have a realistic hope of completing at least one set, and to train with that as their goal. Dende is however afraid of the Dragon Balls being misused, and so he makes these new ones weaker than those of old, capable of granting only limited types of wishes.
[Ref: From the DBO timeline.]

AGE 1000 (#DBO3) (#1000)
--DBO: Through two and a half centuries of interbreeding, Saiyan genes have spread thoroughly among Earthlings, giving the race unknown hidden potential.
[Ref: From Suzaku/Amaranth_Sparrow’s translations. This is the explanation for why Earthling characters in the game can potentially become Super Saiyans.]

--DBO: Miira uses the Red Pants Army and Freeza’s remnants to seize more and more control of the Earth. In order to become even stronger, he and his “Time Breakers” use a time machine to travel to the past in an attempt to steal Son Goku’s DNA. The Time Breakers’ actions cause time to begin to unravel, creating time rifts that suck people through time.
[Ref: General background from the game, mostly from Suzaku/Amaranth Sparrow’s translations.]

DBO: Guided by Time Patroller Trunks, new heroes avert the threat posed by the history-warping Time Breakers
--Among Earth’s 3 races (Human, Namekian, and Majin) many young warriors called “new champions” appear, and continue training and adventuring in order to oppose the various threats facing the Earth.
--Trunks recruits some of these young warriors into his “Time Patrol”, taking them into the past to combat Miira, the Time Breakers, and the mysterious mastermind Towa. Thanks to them, it looks as if the multiple diverging histories have been safely repaired back into one…However, the roots of evil still remain within the shadows and crevices of history.
[Ref: From the DBO timeline, combined with other general DBO info. This era is the main setting of DBO.]

AGE 1267
--DBZ Episode 199: The East Kaio believes the fighters from her galaxy will be strong enough to take on Goku and Paikuhan by this time.
[Ref: In the episode she says they won’t be ready for 500 years].

AGE 1967
--DBZ Episode 196: In the afterlife, the South Galaxy martial artist Catapi hatches from his cocoon.
[Ref: The episode says this will happen in 1,200 years, so this is that long after Age 767.]

AGE 2000
--DBO: In the Demon Realm, the “pale man” Miira is created. Though the details are unclear, it’s thought that his creator is the mysterious “Towa”, who may be a Makaioshin. The two of them form the “Time Breakers” and invade the past, using mind-control devices to interfere with history.
[Ref: General information on DBO, taken from Amaranth_Sparrow’s translations. Actually, some of Suzaku's info made it sound like 2000 was when Miira attacks Earth, though the DBO timeline places this in 998. I'm assuming that 2000 is Miira's home era and that he goes from there to Earth in 998, which he then uses as his base to attack the past. Towa wears what look very similar to Potara earrings and is widely speculated to be a Makaioshin, explaining why Toriyama randomly introduced the concept in the SEG: Character Volume. As far as I know though, this is so far unconfirmed. She’s also thought to be Miira’s creator, but this is likewise I think unconfirmed.]

AGE 2012
--The Mayan calendar predicts the end of the DB World.
[Ref: OK, so I made this one up.]

AGE 2756
--DB Episode 153: Had Goku extinguished the Furnace of Eight Trigrams, this is the earliest point by which the furnace could have been re-lit. In the meantime Earth would have been made into a living hell due to the spirits of the dead being unable to pass on into the afterlife.
[Ref: In the episode Annin says it would take at least 2,000 years to start the furnace back up again.]

AGE 5102
February
--If Bulma and co. had traveled to Namek on a spaceship equipped with Dr. Briefs’ fastest rocket (the fastest on Earth at the time), then they’d have arrived just about now.
[Ref: In Chapter 243 Bulma says this will take 4,339 years and 3 months, so this is that long after November, Age 762.]

AGE 9763
--DBGT: Sea Turtle dies?
[Ref: In GT Episode 64, he says sea turtles supposedly live for ten thousand years, though “ten thousand” is a heavily symbolic number in Japanese and probably meant metaphorically for a very long time.]

That is all.

[TheDevilsCorpse]

This is a whopper of a thread...I'm not sure when I'll have time to get through it all. I do commend you for chucking it out so quickly, if your tweet the other day was when you really started.

[gohan2k]

Wooow this is just amazing!!

It's gonna take me a while to go through all this but so far there's so really awesome stuff in here I didn't know.

Thanks for the credit as well, I didn't expect that but was very happy to be of some use!!

November 21st, Age 762
--Vegeta arrives at Planet Freeza No.79, one of Freeza’s bases. After his injuries are healed, he learns that Freeza has gone to Namek to get the Dragon Balls there, and immediately sets off for Namek himself to get them first.
--DB Chapter 246 (DBZ 52) is partially set on this day.
[Ref: Date from Daizenshuu 7. In Chapter 246 Vegeta is said to reach Planet Freeza 18 days after leaving Earth, so this is that long after the 3rd. Daizenshuu 7 has Vegeta’s healing wrap up on December 13th, 22 days after he reaches Planet Freeza, though the chapter gives no indication of that long passing. We know Vegeta reached Namek the same day as Bulma (which Daizenshuu 7 dates as December 18th). I think the assumption here is that Vegeta’s ship must be as fast as Ginyu and co.’s ships, which were capable of reaching Planet Namek in 5 days starting from Planet Freeza No.79. Assuming that leaves a 22 day discrepancy: Bulma and co. leave Earth 11 days after Vegeta does and take 34 days to get there, so they take 45 days to reach Namek total, whereas Vegeta takes only 23 (18 to Planet Freeza and 5 to Namek), yet they reach there at almost exactly the same time. So that’s why the timeline has Vegeta’s healing take 22 days, to correct the discrepancy. However, I personally think it’s easier to just say that Vegeta’s ship was much slower than Ginyu and co.’s.]

Yeah I'd assumed that as well. It's stated in the anime (not sure about the manga) as well that when Vegeta arrives on Planet Freeza No.79 the controllers say that Freeza had "just left", presumably going straight to Namek and I honestly can't see them being on Namek for any longer than one or two days before everyone else got there so I think it's safe to assume that they left a day before Vegeta was healed and got there a day before Vegeta and everyone else did.

In those healing chambers it can't take more than a few hours to entirely heal someone so 22 days to heal is more than a bit of a stretch.

I'd also like to note this all wouldn't be a problem if it weren't for the anime only scene showing the Ginyu Force on Planet Freeza #79. The manga doesn't show them at all until they arrive on Namek so manga-wise they could've been a lot closer hence the shorter journey. It's only that anime scene that causes the problem.

Wow, amazing work . This will take some time to read.

65 MILLION YEARS AGO?
--On Earth, the dinosaurs stubbornly refuse to go extinct.

This had me laughing

In the DBO timeline , year 801, Goku ist stated to be 64 and Vegeta 67. Is that right? Shouldn't there either be a 5 or 12/13 year difference between them ?

Yeah, I think he made a little error there.
Goku was born in AGE 737. So, in AGE 801, he would be 64, physically 57. (~8 years dead, ~1 year in RoSat in 2 trips)
Vegeta was born in AGE 732. So in AGE 801, he would be 69, physically 71. (~3 days dead, ~2 years in RoSaT in 2 trips)

I didn't read the full thing yet, but it's very well done.

And I love those little Easter Eggs:

AGE 777
--The luckiest year ever.

This is amazing. I love how creatures that were supposed to be extinct "stubbornly refused to".

Jesus Jake, you really don't sleep.

[SylentEcho]

OMG! Thank you Herms.

This is so cool, I'm saving all of that. I'll read the whole thing tonight after I'm back home.

if your tweet the other day

/\ About that. What's your twitter Herms?

[Perfect]

Bah, that's the best time line I've ever seen anyone create. It makes me wanna reform mine a bit, but nothing of that length... Great job though, I dunno how long it's gonna take me to read through every bit of it.

[dprez]

Beautiful. This deserves a good sit down and read through. Bookmarking now! Reading every bit of it later!

The beginning of the DragonBall World all the way to the Mayans predicting the end of the DragonBall world.

So it all ends with the death of the sea turtle...

Thanks so much for all the time and effort it took to compile this information. I must have MORE! I'm going to make this last as long as I can, I'm only going to read a paragraph a day and dwell on that for an entire day before I read the next entry.

>_> You might want to speed it up just a tad bit more there, this thread literally will take about three years or so at that rate.
