Age Calculator

The Age Calculator takes your date of birth and works out your exact age in years, months, days, hours and minutes as of today, along with a countdown to your next birthday and a few fun life statistics. The result updates the instant you enter a date, so there is no waiting and no need to recalculate manually as the day goes on.

People use it to confirm an exact age for forms, applications and eligibility checks, to plan birthdays and anniversaries, or simply out of curiosity about how many days they have been alive. It removes the awkward guesswork of counting across different month lengths and leap years, which is exactly where manual age calculations tend to go wrong.

The calculation runs locally in your browser, so your date of birth is never sent anywhere or saved. With no install and no sign-up required, it is a quick and private way to get a precise age the moment you need one, whether for paperwork or just for fun.
