Frequently Asked Questions

How is age in years, months and days calculated?

The tool counts full years from the birth date, then full months for the remainder, then leftover days — the same convention used on official forms.

Are leap years handled?

Yes. February 29 birthdays and leap-year arithmetic are handled correctly, including day counts across leap years.

Can I calculate age at a past or future date?

Yes — set any 'as of' date to compute age at a specific moment, past or future.

Is the data stored anywhere?

No. Dates are processed in your browser only and never transmitted.
