Next Leap Year Finder

You need to know when the next February 29 lands: a four-year contract, a yearly billing job that must not fire on a date the calendar skips, or simply a relative born on the 29th who only gets a real birthday once in a while. The rule sounds trivial until the century exception shows up and quietly breaks the arithmetic you had in your head.

A year is a leap year when it divides by 4, except that multiples of 100 are skipped unless they also divide by 400. That is why 1900 had no February 29 while 2000 did. The search here starts at the year you typed, not at the year after it. Type 2024 and you get 2024 back, because 2024 already is a leap year. To skip past it, type 2025.

The gap between leap years is not always four. Around a century year that fails the 400 test it stretches to eight, as it did from 1896 to 1904 and as it will from 2096 to 2104. Worth checking if your schedule crosses 2100. Everything is computed in your browser, nothing is uploaded. The page only reports the year, it does not validate dates or count deadlines.
