How to use the age calculator
Pick your date of birth. Leave the second date as today or choose another date to see your age on that day.
How the age calculator works
The calculator subtracts the birth date from the chosen date, borrowing days from the previous month when needed. It also shows total months, weeks and days between the two dates.
