What would you like to do next?
Calculate your age
Enter your date of birth above and your exact age is worked out instantly, broken down into years, months and days, plus your total days lived. The calculation uses the real calendar, so leap years and different month lengths are handled correctly. Everything runs in your browser and nothing is stored.
How it works
The tool counts full years from your birthday, then the remaining months and days up to today, giving the precise age rather than a rounded figure.
Frequently asked questions
How is age calculated?
It counts complete years since your birth date, then the leftover months and days up to today, using the real calendar including leap years.
Is my date of birth stored?
No. The calculation happens in your browser and your date of birth is never uploaded or saved.
