I saw when i was in Japan a various billboards marking a 25 hour service I thought it was some kind of mistake but apparently they call 1 am the hour 25...I think I saw it in Okinawa

As far as I know, that's actually used, when something starts in the "old" day and continues into the "new" day.

See also May 35th.

For what it's worth, leap day is at the "end" of a year. It's just a year that starts in March—an assumption shared with several other odd properties of this calendar.

This is why September, October, November and December are named after the numbers 7, 8, 9 and 10: they are the 7th, 8th, 9th and 10th month if you start the year in March, like we used to.

It’s more than just 25, they often go to 29, to indicate 5am. They do this to make it clear that it is an overnight service starting in one calendar day and terminating in another. It’s not just a simple substitute for “1 am”.

I don't get it.

At least New Year’s Day no longer falls on 25th March.

Depends, in the northern hemisphere this would be when spring is starting, so when the whole nature comes to life full power. Might be more appropriate, as a start of a new year, instead of choosing the time when the cold starts..

Consistency is for small minds. I expect aliens to have much broader issues with time keeping.

Rotations of different galaxies? Weird alien rulers imposing their names like "X Æ A-12" for 3rd rotation even if 12 is in the name.

Having video calls scheduling is hard between Earth time zones - good luck scheduling video call between two galaxies.

Since when do we assume everyone uses the same calendar?

Yeah seeing this today is funny given today begins Rosh Hashanah, the Hebrew new year. But I imagine _most_ countries of the world use the gregorian, especially those on english-speaking sites

Isn't it also about as likely that the aliens will have an even more convoluted calendar, and may even consider ours simple?

I'm always amused by the fantasy that aliens are more likely to be rational and have far less convoluted systems than we do. It's some manner of borderline religious, faith-based notion about the assumed nature of aliens. People seem to get quite upset if you intrude on their fantasy about what aliens must surely be like (not like us, far better than us; humans are the primitive dredge of the universe basically). Des…

There is one defining difference between us, and aliens that visit earth.

They managed interstellar travel, we did not. That inherently puts them at an advantage to us. Definitely a technological advantage. Hence it makes sense to assume (with medium confidence) that such aliens will be better at science than us. Assuming that they will therefore be more rational than us is not much of a leap.

In Japan, clubs will announce opening times like "Friday 22:00〜27:00" meaning 10PM to 3AM the following day
