Leap Year Rules

There is a leap year every year whose number is perfectly divisible by four - except for years which are both divisible by 100 and not divisible by 400. The second part of the rule effects century years. For example; the century years 1600 and 2000 are leap years, but the century years 1700, 1800, and 1900 are not. This means that three times out of every four hundred years there are eight years between leap years. 97 years out of every 400 are leap years. So that means that I will have a birthday in 2096 and then I won’t get another one for eight years in 2104. cool huh!!! I found this information at the Western Washington University Planetarium website. (http://www.wwu.edu/depts/skywise/leapyear.html)
