Why 1999 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. 1999 is not divisible by 4 (1999 ÷ 4 = 499.75), so it cannot be a leap year. The nearest leap years are 1996 before it and 2000 after.
