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. 1791 is not divisible by 4 (1791 ÷ 4 = 447.75), so it cannot be a leap year. The nearest leap years are 1788 before it and 1792 after.
1791 has no February 29, February ends on the 28th. The closest leap day is in 1792, when February 29 falls on a Wednesday. If you are counting toward a leapling birthday or a date-sensitive deadline, that 1792 leap day is the one to watch.
1791 runs 365 days, or 52 full weeks plus 1 day. The leap year before 1791 was 1788 and the next one is 1792, keeping the familiar four-year rhythm.
