How the age is calculated
The calculator counts complete years first, then complete months, then the remaining days, taking into account the different lengths of months and leap years. It also shows the total number of days lived and how many days are left until the next birthday.
Uses
- Checking age requirements on a specific date (school enrollment, retirement, sports categories).
