Questions

How is age calculated?

By counting whole years, then whole months, then the days left, from the date of birth to today or any date you choose. Someone born on 15 May 1990 is 36 years, 4 months and 13 days old on 28 September 2026.

What about birthdays on 29 February?

In years without a 29 February, the birthday is counted on 28 February, so a new year of age starts then. Some countries count it on 1 March instead for legal purposes.

Can I find an age on a past or future date?

Yes. Change “Age on” to any date, for example the day of an exam or a trip, to see the age then.

Is it free? Do I need an account?

It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
