Leap Years and Extra Days

[Pebbilita]

Hi everyone this is my first question...it relates to another question asked ages go� if we get another 24 hours every leap year, we get an extra 4 minutes on that day. So should we be having an extra extra day every 360 years? (i.e. all the extra 4 minutes that make up a day)

I'm working from memory here, but there is a rule in the calendar about not having a leap year on years that are evenly divisible by 400. I'm not sure why that rule didn't apply in 2000. It's been in the back of my mind to find out about that, but other life issues have prevented it. Perhaps someone here knows more.

. . . only centurys that are evenly divisible by 400 are
leap years

[mibn2cweus]

1 year = 525 948.766 minutes
or
1 year = 365.242199 days

therefore, every leap year is about three-fourth's of an hour shy of a full day. This is overly compensated by not having a leap year every 100 years and so every 400 years is a leap year giving on average 97 leap days every 400 years although there are only really 96.8796 . . .
. . . close enough?

Yes. Thank you!
