Frequently asked questions
How is age calculated exactly?
We count full years from the birth date, then the remaining full months and days, accounting for the different lengths of months.

Yes. Change the "age at" date to any date to see the age on that day.
Is my birth date stored?
No. The calculation runs in your browser and nothing is sent or saved.
