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. 1909 is not divisible by 4 (1909 ÷ 4 = 477.25), so it cannot be a leap year. The nearest leap years are 1908 before it and 1912 after.
1909 has no February 29, February ends on the 28th. The closest leap day is in 1912, when February 29 falls on a Thursday. If you are counting toward a leapling birthday or a date-sensitive deadline, that 1912 leap day is the one to watch.
1909 runs 365 days, or 52 full weeks plus 1 day. The leap year before 1909 was 1908 and the next one is 1912, keeping the familiar four-year rhythm.
