Age calculator
Enter a date of birth for the exact age in years, months and days, the day of the week you were born, and a countdown to the next birthday.
How age is counted
Age goes up on each birthday. The calculator counts whole years, then whole months, then the days left over, the same way forms and official documents do. Change Age on to see how old someone was, or will be, on another date, for example the closing date of an application.
Nothing you type is sent anywhere; the calculation runs on your device.
