Just enter your date of birth and the Age Calculator instantly shows your age in years, months and days, plus total weeks, total days lived and the number of days remaining until your next birthday.

Why use an Age Calculator?

Calculating age manually sounds simple but is surprisingly error-prone – especially when months have different lengths, leap years are involved, or the date of birth falls late in the month. A reliable Age Calculator removes all that confusion. Government portals like UPSC, SSC, IBPS, Railway and state-level recruitment boards strictly check age in years, months and days as on a specific cut-off date. Schools and colleges use age in completed years for admissions. Even insurance, loan and pension calculations depend on exact age. One small mistake can mean a rejected application, so it is always safer to use an accurate Age Calculator.

This Age Calculator runs 100% inside your browser. Your date of birth is never sent to any server, never logged and never shared with third parties. Close the tab and the data is gone.

How the Age Calculator handles leap years

Many free age calculators round off months and ignore leap years, which leads to a 1–2 day error. Our Age Calculator uses the actual calendar – including February 29 on leap years – so the result matches what an official verifier would calculate by hand. People born on 29 February also get a correct days-to-next-birthday count.
