What is an age calculator? An age calculator finds your exact age from your date of birth, expressed in years, months, and days plus the total days you have lived.
Enter your date of birth and the calculator measures the time from that date to today (or any reference date you choose), giving your age as a number of years, months, and days.
It subtracts the birth date from the current date one unit at a time, borrowing days from the previous month and months from the year when needed, so leap years and the differing lengths of each month are handled correctly.
The total days lived is the whole number of days between your date of birth and today. The calculator shows this figure alongside your years, months, and days.
