Age Calculator

Frequently asked questions

How is my exact age calculated?

The tool compares your date of birth with the target date and borrows days and months as needed, so you get a precise age in years, months and days.

Can I check my age on a past or future date?

Yes. Change the Age at date field to any date and the calculation updates, which is useful for eligibility checks.

What extra information is shown?

Below your exact age you also get the total number of days, hours and minutes you have been alive, plus a countdown to your next birthday.

Does it handle leap years?

Yes. The day count is based on real calendar days, so leap years are included automatically.
