About

This site counts civil age from dates you type. It uses the Gregorian calendar, which is the calendar on most birth records and passports. It does not ask for a place of birth, and it does not keep a list of places.

A full year is counted when the anniversary has been reached. The remaining span is then split into months and days. If a birth day does not exist in a later year, the anniversary is the last day of that month. For a 29 February birthday, that day is 28 February.

The calculator gives the age on today or on a day you pick. Age difference uses the same count between two dates of birth.

Where ads sit

Ads from ExoClick pay for this site. Each placement keeps a fixed size so the page does not jump when an ad arrives, and a placement that does not fit your screen is never loaded.
