Next Leap Year Finder
Find the next leap year after any year, check whether a year is a leap year, and see the previous leap year and the next several to come.
How it works
a year is a leap year if it is divisible by 4, except centuries, which must also be divisible by 400 · next leap year = the smallest later year passing this test
Leap years keep the calendar aligned with Earth’s orbit, which takes about 365.2425 days. The Gregorian rule adds a February 29 in years divisible by four, but skips century years unless they are divisible by 400 — so 1900 was not a leap year while 2000 was. Because most leap years are simply the next multiple of four, the next one is usually within four years, but around skipped centuries the gap stretches to eight (for example, 1896 to 1904).
Worked example
Starting from 2026 (not divisible by 4, so a common year), the next multiple of four is 2028, which is not a century, so 2028 is the next leap year. February 29, 2028 falls on a Tuesday, and the following leap years are 2032, 2036, 2040 and 2044.

Frequently asked questions
How do I tell if a year is a leap year?
If it divides evenly by 4 it is a leap year — unless it is a century year (ends in 00), which must also divide by 400. So 2024 and 2000 are leap years, but 1900 and 2100 are not.
Is the gap between leap years always four years?
Almost always, but not around skipped centuries. Because 1900 and 2100 are not leap years, the gap there stretches to eight years — 1896 to 1904, and 2096 to 2104.
Why do we need the 400-year rule?
A pure four-year rule overcorrects, adding slightly too many days over centuries. Dropping three leap days every 400 years (the century exceptions) brings the calendar’s average year to 365.2425 days, matching the solar year closely.
