Leap year check
No — 2010 is not a leap year.
2010 is not divisible by 4, so it is NOT a leap year — February has the usual 28 days.
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. 2010 is not divisible by 4 (2010 ÷ 4 = 502.50), so it cannot be a leap year. The nearest leap years are 2008 before it and 2012 after.
2010 has no February 29 — February ends on the 28th. The closest leap day is in 2012, when February 29 falls on a Wednesday. If you are counting toward a leapling birthday or a date-sensitive deadline, that 2012 leap day is the one to watch.
2010 runs 365 days, or 52 full weeks plus 1 day. The leap year before 2010 was 2008 and the next one is 2012, keeping the familiar four-year rhythm. To do date math across 2010 — 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.
