How it works

This counts the exact time between a birth date and today, carrying days and months the way a calendar does — so the result matches how you’d actually state someone’s age, not just a rough subtraction of years.

Frequently asked questions

Does it handle leap years?

Yes. Because it works from the real calendar dates rather than a fixed 365-day year, leap days are counted correctly in the totals.
