How this count works
A Gregorian year is a leap year when it is divisible by four, except a century year must also be divisible by four hundred. The extra date belongs to February.
This gives the number of calendar dates, not the exact time Earth takes to orbit the Sun.

A worked example
The year 2000 has 366 days. It is divisible by four hundred, so the century exception still permits February 29.
