The year 1 is also completely arbitrary though? Humans existed long before then too. It doesn't really matter when the epoch is, as long as everyone uses the same one, and negative values are supported as appropriate
Exactly my point. The rest of humanity uses year 1 as the epoch.
It's irrelevant to my point though. Just because the standard is used by 99% of people instead of 100% doesn't mean programmers should invent a new one, for the same reason they chose January 1st 1970 and not November 15th 1970 or any other day of the year. There's only one obvious choice.
The rest of humanity uses a variety of reckoning systems:
Notably, the newest entry on that list is "Unix time". Just because there's already more than one entry on the list doesn't mean a small group of people should add another. That's not even "there are now 14 standards" that's just deliberately adding to the pile.
Isn’t this just the “no true scotsman” defense, but for calendars?
Regardless, just because the standard is not used by 100% of humanity doesn't justify programmers coming up with their own calendar instead of using the obvious choice. It's unnecessary.
There's only two calendars where it's been 2023 years.
