Why 2121 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. 2121 is not divisible by 4 (2121 ÷ 4 = 530.25), so it cannot be a leap year. The nearest leap years are 2120 before it and 2124 after.
