FAQ
A year is a leap year if it is divisible by 4, except for century years (divisible by 100), which must also be divisible by 400. So 2000 was a leap year, but 1900 was not.
Earth takes approximately 365.25 days to orbit the sun. Without leap years, our calendar would drift about 6 hours each year, causing seasons to shift over time.
Leap years occur every 4 years in most cases, but are skipped on century years not divisible by 400. The average is one leap year every 4 years.
