Frequently asked questions

What is this commonly used for?

Years of service, years married, or years since a milestone event are common uses — this calculator gives a clean whole-years figure rather than a decimal approximation.

I need the years/months/days breakdown instead — where's that?

See the Date Difference Calculator for the same calculation shown as a full breakdown.

Does this account for leap years?

Yes — the underlying arithmetic is fully calendar-accurate, correctly handling leap years and varying month lengths.
