How it works
The calculator subtracts your date of birth from the second date, borrowing days and months where needed, so the result is your age in complete years, months and days. Total days is the exact number of days between the two dates.
By default the second date is today. Change it to find your age on any date, for example for a form or a milestone.
Example
Someone born on 15 June 1990 is, on 20 September 2026, 36 years, 3 months and 5 days old.
