Frequently asked questions
How is the exact age worked out?
We count full calendar years, then full months, then the remaining days between your birth date and the target date. Leap years are handled automatically because the calculation uses real calendar dates, not an average year length.
What if I was born on 29 February?
On non-leap years your birthday is counted as 1 March for the “next birthday” countdown, which matches how most calendar systems treat a 29 February birthday in a year without that date.
Can I find my age on a past date?
Yes. Set the “age at date” to any date after your birth date — for example, the date of an old photo — and the calculator shows how old you were then.
Is my date of birth sent anywhere?
No. The calculation runs entirely in your browser and your date of birth never leaves your device. Use it as a age calculator free — no signup, nothing to install.
