How to use the Age Calculator
- Select your date of birth.
- Optionally change the “age on” date (defaults to today).
- See your exact age, total days lived and days until your next birthday.
How age is calculated
The calculator counts complete years first, then the complete months after your last birthday, then the remaining days. Leap years and months of different lengths are handled automatically, so the result matches how age is counted on official documents.
Common uses
- Checking age eligibility for exams, jobs or government schemes.
- Finding the exact age on a specific past or future date.
- Counting down to a birthday or anniversary.
Frequently asked questions
How are people born on 29 February handled?
In non-leap years their birthday is treated as 28 February for the next-birthday countdown, which is the most common convention.
Can I calculate age on a future date?
Yes. Change the “age on” date to any date and the calculator shows how old you will be on that day.
