How to Calculate Your Age

Calculating your exact age takes more than subtracting birth year from current year. Leap years, month lengths, and whether your birthday has passed all affect the answer.

Use the calculator to find your age today or enter a comparison date to calculate how old you were, are, or will be on a specific date.
