Your exact age.
Down to the day.
Find an exact age on any date for forms, eligibility checks or curiosity. Leap years and month lengths are handled for you.
How exact age is worked out.
The same way people count it: whole years first, then whole months, then the remaining days.
The calculator counts complete years since the birth date, then complete months, then the days left over, borrowing the length of the previous month when needed. Total days use calendar dates only, so time zones and daylight saving cannot shift the answer by a day.
Common uses
- Checking age eligibility on a specific deadline date for exams, jobs or visas
- School admission cut-off dates
- Insurance or pension forms that ask for age on a given day
- Counting days since or until an anniversary
Always follow the exact rule in the official instructions; some systems count age differently, for example by completed years only.
How are leap years handled?+
Each month uses its real length, including 29 days in February during leap years, so results stay exact.
What if I was born on 29 February?+
In non-leap years the next birthday is counted as 28 February, which is the most common convention. Some legal systems use 1 March instead.
Can I calculate age on a future date?+
Yes. Change ‘Age on this date’ to any future deadline, such as the last date to apply for an exam.
Is my date of birth stored?+
No. The calculation runs in your browser and nothing is saved or sent.
