About this tool
Exact age is needed for job applications, exams, visas and admissions that set minimum or maximum ages on a certain date. This calculator counts full calendar months and days, so it handles leap years and months of different lengths correctly.
Frequently asked questions
How is age calculated?
It counts complete years first, then complete months, then the remaining days between the two dates.
What if I was born on 29 February?
In years without a 29 February, your birthday is treated as 1 March for the countdown.
Can I calculate age on a future date?
Yes. Change the “age on” date to any date, for example the closing date of an application.
