hahahha idiot a year is not constant, so the average year would actually be 365.25 days 🤓

And take back another .0075 for the
"no leap years on multiples of 400""no leap years on multiples of 100 that are not also a multiple of 400" rule.2

Wait, there wasn't a leap year in 2000?

u/ThirstyWolfSpider 6h ago
Oops, you're right. I meant "no leap years on multiples of 100 unless they're also a multiple of 400".
1900: not a leap year
2000: leap year
2100: not a leap year

Oh, why would that be?

Like the leap year rule itself, it's a slightly better approximation than not having that complication. The real number of days in a year is closer to 365.2422, and slightly variable. Starting with a 365 base (0.0663% error), adding a leap year every 4 gets us 365.25 (0.00213% error), removing leap years for multiples of 100 takes it to 365.24 (0.000602% error), and adding the leap year back for multiples of 400 takes it to 365.2425 (0.0000821% error).

Ohhh got it so the ball should drop at 6 am instead of 12 am?

u/ThirstyWolfSpider 5h ago
Yes, but it's all a matter of priorities. People typically want an integer number of days in a given year, and that wins out.
