FAQs
Is this age calculator free?
Yes. It is completely free with no sign-up and no limits.
How accurate is the calculation?
The calculator borrows days and months exactly like a calendar does, so leap years and months of different lengths are handled correctly.

Yes. Just enter their date of birth instead of yours.
Is my date of birth stored anywhere?
No. The calculation runs entirely in your browser and nothing is sent or saved anywhere.
