Age calculator
This free age calculator works out your exact age from your birth date to today in years, months and days. Pick your birth date and you'll instantly see your full age. It's handy for forms, registrations or simple curiosity.
How the calculation works
The calculator subtracts the birth date from today's date and breaks the result into full years, remaining months and days. The differing number of days in each month is accounted for, so the result is calendar-accurate. Everything runs in your browser and no data is sent anywhere.
Worked example
For a birth date of 15 March 1990, the calculator shows how many years, months and days have passed as of today. The result updates automatically each day.
