Leap years

In the table below you can see all leap years between 2021 and 2100.

When is the next leap year?

A leap year is a year with 366 days instead of 365, every 4 years in February one extra day is added. This is done because one year doesn't contain 365 days but 365.25 days. By adding once in the 4 years one extra additional day this problem is solved.

Any year that is divisible by 4 is a leap year, such as 2016, 2020, 2024, 2028.

Note: The above rule does not apply to century years.

Centuries such as 1900 and 2000 only have a leap day if they are divisible by 400.
1900 is divisible by 4 and also by 100, but not by 400, so not a leap year.
This means that centuries are only a leap year if they are divisible by 400.

So 1900 is not, 2000 is, 2100, 2200, 2300 is not, but 2400 is another leap year.
