The nearest leap years are 1852 before it and 1856 after.
1855 has no February 29, February ends on the 28th. The closest leap day is in 1856, when February 29 falls on a Friday. If you are counting toward a leapling birthday or a date-sensitive deadline, that 1856 leap day is the one to watch.
1855 runs 365 days, or 52 full weeks plus 1 day. The leap year before 1855 was 1852 and the next one is 1856, keeping the familiar four-year rhythm.
