About the Age Calculator
The Age Calculator measures elapsed calendar time between a date of birth and a selected calculation date, including years, months and remaining days.
Calendar calculation
Complete years are counted first, then complete months, followed by remaining days. This calendar method handles months with different lengths more clearly than dividing total days by 365.
Birthday note
For a February 29 birth date, a non-leap-year birthday is treated as February 28. Results always depend on the selected calculation date.
Example
From January 15, 2000 to March 20, 2025, the calendar difference is 25 years, 2 months and 5 days.
