If a year is divisible by 100 then it is not a leap year ...

Leap years occur every 4 years. 25 times in 100 years. 2000 was a leap year. I have reason to believe every year divisible by 4 is leap.

Oh, I was wrong. Wikipedia showed me that, although 2000 is leap, multiples of 100 are only leap at each 4 centuries. I was completely unaware.
