About the Age Calculator
Find your exact age — or anyone's — on any date. The calculator handles leap years and months of different lengths correctly, and also shows total months, weeks and days lived, the weekday you were born on, and how many days remain until your next birthday.
How to use it
- Enter the date of birth.
- Optionally change the “age on” date.
- Read the results.
Good to know
- People born on 29 February have their birthday counted on 1 March in non-leap years.
