Reply to comment by theBeardsley in ELI5 What is a leap year and why does it occur? by Own_Grapefruit8750

The exceptions are years multiple by 400. Those we do not make leap years even though they are divisible by 4. And we do that because it is actually closer to 365.246 days to a year, and that makes it pretty much consistent over the course of even thousands of years.

The opposite - years divisible by 400 are leap years, but other years divisible by 100 but not 400 are not leap years. 2000 was a leap year and it's divisible by 400.
