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. 3003 is not divisible by 4 (3003 ÷ 4 = 750.75), so it cannot be a leap year. The nearest leap years are 2996 before it and 3004 after.
3003 has no February 29, February ends on the 28th. The closest leap day is in 3004, when February 29 falls on a Wednesday. If you are counting toward a leapling birthday or a date-sensitive deadline, that 3004 leap day is the one to watch.
3003 runs 365 days, or 52 full weeks plus 1 day. The leap year before 3003 was 2996 and the next one is 3004, keeping the familiar four-year rhythm. To do date math across 3003, counting days to a deadline, an age, or an anniversary that crosses a leap day, use the days-between calculator, which handles leap days automatically.
