Your exact age, to the day
Enter a date of birth and the calculator shows the exact age today in years, months and days, counted on the calendar so leap years and month lengths are handled correctly. You'll also see the total number of months, weeks, days and hours you've lived, the weekday you were born on, and how many days are left until your next birthday.
Change the “Calculate age on” date to find your age on a specific day — often needed for exam and job applications that set an age limit “as on” a cut-off date.
