Age and date calculator

Civil dates only. A 29 February birthday is observed on 28 February when the year is not a leap year.

Calculate an age, the days between two dates, or a date moved by whole days. Only the dates and the day count you enter are used. Nothing else is added.

Submit the form to calculate a result from the values on this page. The result follows only the rules stated above. It illustrates those inputs and is not a statement from a bank or a card issuer.
