Your dates stay in this browser. This calculator does not send them to a processing server.

How to use the age calculator

  1. Enter your date of birth.
  2. Leave “Calculate age on” set to today, or choose another date to calculate your age at that time.
  3. Select Calculate age to see the completed years, months, and days.

Example: If your date of birth is 15 March 2000 and you calculate on 27 October 2026, the result is 26 years, 7 months, and 12 days.

The result uses calendar dates and does not depend on your time of birth or time zone. For a birth date of February 29, a non-leap-year anniversary is treated as February 28.
