Frequently asked questions
How do I find my age on a specific date?
Change the "Age on date" field to the date you need, such as the cut-off date given in an exam or job notification.
How are leap years handled?
The calculator uses the real calendar, so leap years and months of different lengths are counted correctly.
Is my date of birth saved?
No. The calculation happens in your browser and nothing is sent to our server.
