they could have saved everyone a whole lot of trouble by having 13 months with 28 days each, no cross calendar day stuff, no leap year stuff, would be truly the most perfect calendar ever made forever and would simplify working of everything on the planet by a mile

What? 13*28=364 So, missing ~1.25 days every year (instead of ~0.25 days each year with a 365 day calendar). How does this solve leap years?

Every month would be the same number of days! Every week day would be the same date every year!

And you can have a "year day (or 2 on leap years) at the end to round the calendar out to 365 days.

It makes too much sense, that's why it will never happen. https://en.m.wikipedia.org/wiki/International_Fixed_Calendar

1 or 2 "year day" holidays at the end of the calendar which aren't part of any month

12 can be divided by 2, 3, and 4.

13 is a prime number.

There's a reason the number 12 comes back to often for these types of things.

And the current calender really isn't that much of a hassle.

Summary: The historical start of the year is March 1st. That's also why some months have misleading Latin names that are off-by-2.

> some months have misleading Latin names that are off-by-2

To expand on this: "sept-" is a prefix meaning 7, like septuplets. But September is the 9th month of the year. "oct-" means 8 like octagon, but October is the 10th month of the year. And so on for November and December.

Well, there's more to it than that: the leap day is really February 24th; there are "two" February 24ths. > Except that isn’t exactly true. The Romans did not add an extra day on February 29, but on February 24, which is where the more complicated answer begins. The Romans kept a calendar by counting backwards from specific set times of the month, the kalends (March 1), the nones (March 7) and the ides (March 15). Ju…

I would really like to go back to the earlier system, where there was no January or February, and we just stop having time in the winter until someone important announces it is the new Year in March.

Which seems to be tens of thousands of years old !

Curious, how would you fix the leap year stuff?

Sounds boring. What would we have to talk about on a slow Wednesday morning? :)

In French, leap years are still called bisextile. I had no idea why.

It's the same in portuguese, 2024 is an "ano bissexto". I never stopped to ask what the hell does "bissexto" means, but now I know... I guess?
