❓ FAQ

How is age calculated?

We compute the difference between your birth date and the target date, accounting for varying month lengths and leap years, then express it as years, months and days.

Can I calculate age on a future date?

Yes. Change the "Age at date" field to any date to see how old you (or someone) will be then.

Is my birth date stored anywhere?

No. Everything is calculated locally in your browser and nothing is uploaded.
