About Age Calculator
This age calculator works out your exact age from your date of birth in years, months and days. It also shows your age in total months, weeks and days, a countdown to your next birthday and your zodiac sign.

It handles leap years and birthdays on 29 February correctly. The calculator is free, needs no sign-up, and your date of birth stays on your device.
