About
Age Calculator turns a date of birth into your exact age in years, months, and days, plus a live countdown to your next birthday and your Western and Chinese zodiac signs. It's precise to the day, not just the year, which matters for anything requiring an exact age. Your birth date is never sent anywhere — the calculation happens entirely in your browser.
Frequently asked
- Is the age calculation exact to the day?
- Yes — it computes the precise number of years, months, and days rather than rounding to the nearest year.
- Does it store the date I enter?
- No, nothing is saved or transmitted; the date of birth only exists on the page while you're using it.
