About this age calculator

Your exact age is not just the gap between two years. This calculator counts full years first, then the remaining months and days, borrowing days from the previous month when your birthday has not yet come around in the current month. This is the way age is normally counted on forms, school admissions and visa applications. Use the "Age at date" field to find how old someone was, or will be, on any particular day.

How to use it

Enter the date of birth.
Leave the second date as today, or pick another date.
Press Calculate to see years, months, days and life stats.
