Calculate age between two dates

An exact age calculation compares the birth date with the selected reference date and accounts for calendar month lengths and leap years. The result is expressed in completed years, months and days. For official forms, use the date and age convention required by the relevant authority.

Can I calculate age on a past or future date?

Yes. Change the reference date to calculate how old someone was on a past date or how old they will be on a future date. Check that the reference date is not earlier than the date of birth.
