Leap years occur every 4 years, except we skip one every 100 years, HOWEVER we skip that skip every 400 years.
2000 was the perfect example: /4 so leap year? well /100 so no leap year? well also /400 so no no = yes leap year.
Basically that one time in our lives we could have witnessed the /100 exception, it actually wasn't, so business (= leap year) as usual.
- debesyla 5y agoI wonder what we will use in 400 years - I think it's possible that this kind of skip is the last one we had... Maybe.
- modulusshift 5y agoDon't fix what ain't broke. the year 2000 was the second skipped skip after 1600. If the Gregorian calendar could make it through those four centuries, with the increasing rate of political and social upheaval, it's not going to change much now. We've got almost 3 more millennia before we've lost a full day compared to the tropical year.
