Why 2000 is 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. 2000 is a century year, but because it is also divisible by 400 (2000 ÷ 400 = 5), the century exception is overridden and 2000 is a leap year. These are the rarest leap years, only one century in four qualifies.
February 29, 2000
Because 2000 is a leap year, it has a February 29, and that date falls on a Tuesday. Anyone born on this date is a "leapling" whose true calendar birthday only comes around every four years. Every date from March 1 2000 onward sits one weekday later than it would in a common year, a quiet side effect of the extra day.
2000 at a glance
2000 runs 366 days, or 52 full weeks plus 2 days. The leap year before 2000 was 1996 and the next one is 2004, keeping the familiar four-year rhythm.
