Frequently asked questions
What is a leap year?
A year with 366 days instead of 365. The extra day, February 29, keeps the calendar aligned with the solar year.
How is a leap year determined?
A year is a leap year if it is divisible by 4. Years divisible by 100 are not leap years unless they are also divisible by 400. So 2000 was a leap year, but 1900 was not.
When is the next leap year?
The result card shows the next three upcoming leap years from your input.
Why does it matter?
Leap years affect age calculations, anniversaries, payroll, and any date math that spans February.
