Calculate Your Exact Age Online

This age calculator tells you how old you are in years, months and days from your date of birth. It also shows the total months, weeks, days and hours you have lived, the weekday you were born on, and a countdown to your next birthday. Everything runs in your browser, so your date of birth is never stored or sent anywhere.

How to use the age calculator

Pick your date of birth. The second date is set to today by default, but you can change it to find your age on any past or future date, such as a school admission cut-off, a job application deadline or a visa date. Press Calculate age to see the result.

How the age is worked out

The tool subtracts your birth date from the chosen date year by year, month by month and day by day. When the day count goes negative it borrows days from the previous month, so the result matches how people normally count age.

Can I check someone else's age? Yes. Enter any date of birth, for example a child's, a parent's or a friend's.
