Age Calculator
Find an exact age in years, months, and days between two dates.
How it works
A calendar calculation, not a rough estimate
The calculator compares the calendar date of birth with your selected date. It borrows days from the previous month when needed, so leap years and months with different lengths are handled correctly.
For example, from September 4, 2000 to September 4, 2026 is exactly 26 years, 0 months, and 0 days.
