Frequently asked questions
What's the actual rule for leap years?
A year is a leap year if it's divisible by 4, except century years (divisible by 100), which must also be divisible by 400 to count. That's why 2000 was a leap year but 1900 was not.
Why does this rule exist?
It keeps the calendar aligned with Earth's orbit, which takes slightly less than 365.25 days — the extra century-year exception corrects for that small overcorrection.
