What Is an Age Calculator?

An age calculator determines your exact age based on your date of birth and today's date. In addition to showing your age in years, months, and days, it can also calculate the total number of months, weeks, and days you've lived.
 

Frequently Asked Questions
 

How is my age calculated?

The calculator compares your birth date to today's date and calculates the difference in years, months, and days.
 

Does this account for leap years?

Yes. Because it uses actual calendar dates, leap years are automatically included in the calculation.
 

Why are months and days different than dividing by 30?

Calendar months have different numbers of days, so the calculator uses actual calendar dates rather than averages.
 

Is my information stored?
