Is my date of birth stored or uploaded?

No. The calculation runs entirely in your browser — nothing is sent to a server or saved.

Can I calculate age on a future or past date?

Yes. Change the “Age at date” field to any date to see the age as of that day.

Using calendar months, the same way people say their age — it borrows the correct number of days from the previous month when needed.
