Age Calculator

Age Calculator turns a birth date into a clear, exact age—without counting by hand.

Enter a birth date and see your age broken down into years, months, and days. The app also shows how many days you have lived and how many days remain until your next birthday. Need age as of a past or future date? Turn on the custom as-of date option to calculate age on any reference day—useful for forms, eligibility checks, and historical records.
