How your age is calculated: The calculator compares your date of birth with the selected calculation date and determines the complete number of years, months and remaining days between the two dates.
The calculator uses calendar dates rather than simply dividing the number of days by 365, which allows it to display your age as years, months and days.
Enter your date of birth and choose the date on which you want to calculate your age. By default, the calculator uses today's date. Your exact age is then displayed in years, months and days. The calculator also shows your total number of months, days and weeks, along with the approximate number of hours and the date of your next birthday.
Select your date of birth from the calendar.
