Yeah, sure, because normal people count form zero…

Have you actually ever watched people counting things?

In a sane world the offset based counting (zero bases) would have never surface (besides in very specific and seldom circumstances).

Also it's a shame that the C languages started to call offset "index" (and there is not even a proper index operator!).

How so? Would 2021-08-12 mean month 08 or month 12? It doesn't matter if it starts from zero, it still looks ambiguous to me.

Also don't forget about year 0 (which doesn't exists and is a single point of failure for so many programs that deal with calculating time between now and a BC date)
