Calendar Dates In The Manga

[MagicBox]

Howdy, everyone! I've got a quick question for all the timeline nuts out there.

I'm browsing through Herms' "The History Of Ever" guide in hopes of finding a list of calendar dates that are confirmed within the manga itself. Basically, I'm looking for dates that are outright stated by either the characters or the narrator.

So far, I've got...

May 7th: The date on which the Tenkaichi Budōkai is always held.

May 9th: The date on which Piccolo Daimaō announces that he has taken over (as well as Japan's official "Gokū Day" out-of-universe).

May 12th: The date on which the Artificial Humans attack near South City.

Am I missing anything? It's entirely possible that I skimmed past something in the guide. Again, I'm only looking for dates that are specifically confirmed in the manga. I'm not interested in anything that's inferred within the guide books. For example, the Daizenshū state that Piccolo Daimaō regains his youth on May 8th because we kinda-sorta see one night passing in the manga itself, but since it's not outright stated, I don't count it.

Thanks in advance, everyone!

The May 7th date shouldn't be counted either, as that too is "just" an inference made in the Daizenshuu, due to fact Piccolo announces Piccolo Day on May 9th and thus the 22nd tournament took place on May 7th.
All the other tournaments are not given specific dates and are certainly not stated to take place on exactly the same date(from a real world perspective huge sporting events tend to fall in or around the same dates fx Champions League Finals in football(soccer for the Americans), so it does make sense to just keep the date).

In the manga it's just May 9th, May 12th, and...ugh, the date of the Cell Games, which is "M 17th" in the original manga and May 26th for the kanzenban and full color manga.

I wonder, if the month of May means something special to Toriyama or whether it's just a complete coincidence.
His birthday is in early April, so it doesn't seem to be that, though it's close.

Thanks very much, you two!

My mistake regarding May 7th. I could've sworn that was mentioned somewhere. Thanks for the correction.

I completely forgot about the Cell Game dates as well. Thanks again!

Well, May 9th is a Japanese number pun on "Goku" (5=go 9=ku), so there's a definite reason for that one at least. The revised Cell Games date just comes from calculating forward from May 12th, but if May 12th itself has any number pun or other meaning, then I'm not aware of it. The original Cell Games date of M 17th seems like Toriyama trying to use weird made-up month names again, like he did in Dr. Slump.
