What this calculator does

This tool finds the date of the next February 29th (leap day) on or after any date you choose, along with how many days away it is.

Worked example

From March 2026, the next leap day is Tuesday, February 29, 2028, since 2028 is the next year divisible by 4 (and not a skipped century year).

Common mistakes

  • Assuming every 4th year is a leap year. Century years not divisible by 400 (1700, 1800, 1900, 2100...) are skipped, though this rarely matters for near-term dates.
