The age calculator works out your exact age from your date of birth: years, months and days, the total number of days you have lived, and how many days are left until your next birthday. The whole calculation runs in your browser, so nothing you type is sent to a server.
How to use it
Pick your date of birth and the result updates instantly — no button to press. You will see your age broken down into years, months and days, plus two extra figures: the total days lived and the countdown to your next birthday.
