Age Calculator formula
Exact age is calculated by comparing birth date with today's date and adjusting incomplete months and days.
The calculator compares your date of birth with today's date and adjusts month and day differences when a birthday has not yet occurred.
If the birth date is 15 January 2000, the result shows completed years plus remaining months and days.
Complete the calculation in three steps
- Select your date of birth.
- The browser calculates completed years, months, and days instantly.
- Check next birthday countdown and total days, weeks, months, and hours lived.
