In the interest of correcting some misinformation, leap day actually happens because it actually takes slightly longer than 365 days for the earth to fully orbit the sun. Without the addition of an extra day every four years, the calendar would eventually slip out of sync with the seasons. In fact, the current Gregorian calendar was designed to keep the date of Easter correct with respect to the vernal equinox.

Interestingly enough, although leap years usually occur in any year that is divisible by four, years that are evenly divisible by 100 but not by 400 are not leap years. Just to keep everything even.

Now, isn't that much more interesting?
