About Exact Age Calculator

exactagecalculator.app is a free, no-signup tool that answers one question precisely: how old are you? Not approximately — exactly, in years, months and days, as of today or any reference date you choose.

Most people need an exact age at the least convenient times: filling a school application, meeting an exam eligibility cutoff, completing a clinical form or a psychology assessment that asks for chronological age, or simply settling a friendly argument about who is older. This calculator handles all of those cases, along with aggregate totals (days, weeks, hours, minutes), a next-birthday countdown and a bit of birthday trivia.

The site is deliberately minimal: no accounts, no ads chasing you across the internet, no data collection of any kind. Dates you enter are processed entirely in your browser and are never sent anywhere.
