The leap-year rule
A year is a leap year when it is divisible by 4, except century years (divisible by 100), which must also be divisible by 400. So 2000 was a leap year, 1900 was not, and 2100 will not be. That is why the average calendar year is 365.2425 days — close to the true solar year of about 365.2422 days.
