Frequently asked questions
How is exact age calculated?
We count full years, then full months, then the remaining days, the same way you'd count on a calendar. Someone born on 15 January 2000 is 24 years, 2 months and 5 days old on 20 March 2024.
What if I was born on 29 February?
In years without a 29 February, your next birthday is shown on 28 February.
Is my birth date stored?
No. The calculation runs in your browser and nothing is sent anywhere.
