Still not weirder than Lunar calendar

Why use celestial bodies at all? Let's bring the Soviet calendar back!

something something every 5 years.

It's not odd as in a more unusual system, but odd in that it is widely incompatible with the calendar of most of the world, but still official calendar. Kinda like the Kodak calendar (which was instead 13 28-day months (364 days), and iirc does the off-day adjustments over the corporate winter holiday...actually pretty reasonable)

Merry Corporate Winter Holiday!

lmao

Not reasonable at all... it's Corporate Summer Holiday around here.

You take that back!

There are good reasons for the Gregorian calendar’s oddities, though. Any simple system stops being simple when you apply it to enough different situations. I am not sure programmers would like it better if each country had a different calendar for each season. Because a day that starts at 6 and ends at 18 would make sense 2 days each years here in Europe. Not even that if you go far enough North.
