Why 2309 is not a leap year

A year is a leap year in the Gregorian calendar when it is divisible by 4, with one exception and one exception to that exception: a year divisible by 100 is not a leap year unless it is also divisible by 400. 2309 is not divisible by 4 (2309 ÷ 4 = 577.25), so it cannot be a leap year. The nearest leap years are 2308 before it and 2312 after.
