Age Calculator
Calculate your exact age in years, months, and days.
How to use the Age Calculator
Pick your date of birth using the date picker and click "Calculate". The calculator instantly shows your exact age in years, months and days. You can also see how many days remain until your next birthday.
Example calculation
If you were born on January 15, 1990, and today is March 10, 2025, the calculator will display: You are 35 years, 1 month and 23 days old.
How age is calculated
The calculator subtracts your birth date from the current date. It first counts the full years, then adjusts the months and days to give a precise result. Leap years are automatically taken into account.

What is the difference between "years" and "days"?
