The nearest leap years are 1588 before it and 1592 after.
1590 has no February 29, February ends on the 28th. The closest leap day is in 1592, when February 29 falls on a Saturday. If you are counting toward a leapling birthday or a date-sensitive deadline, that 1592 leap day is the one to watch.
1590 runs 365 days, or 52 full weeks plus 1 day. The leap year before 1590 was 1588 and the next one is 1592, keeping the familiar four-year rhythm.
