How to calculate your exact age
Enter a date of birth and the calculator works out the exact age in years, months and days, right up to today or any date you choose. It's the precise way to find an age for forms, eligibility checks, birthdays and milestones — no counting on a calendar required.
More than just years
As well as the standard years-months-days breakdown, an age calculator can tell you how many total days, weeks or months have passed, and how long until the next birthday. It's handy for legal age checks, retirement planning and fun facts alike. The calculation runs in your browser, so the date you enter stays private.
