About this tool
Enter a year to see if it has 366 days. A year is a leap year if it is divisible by 4, except century years, which must be divisible by 400. So 2000 was a leap year, but 1900 and 2100 are not.
Frequently asked questions
What is the leap year rule?
Divisible by 4, but not by 100 unless it is also divisible by 400.
Why do we need leap years?
A year is about 365.2422 days, so an extra day every four years keeps the calendar in step with the seasons.
