Frequently asked questions
How is exact age calculated?
We count full calendar years and months from your birth date, then the remaining days - the same way age is written on official documents.
Can I calculate age on a past or future date?
Yes. Change the "Age at date" field to any date to find how old you were or will be on that day.
Is my birth date stored anywhere?
No. The calculation runs entirely in your browser and nothing is saved or sent.
