Age Calculator

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

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

Tips and good to know

Use the Age at date field for official forms that ask for your age on a specific day, such as the closing date of an application. The calculator also shows your next birthday and the weekday you were born. Some programs count age differently, so check their rules.
