Checking age eligibility
Recruitment and admission notifications often define an age limit as on a specific cut-off date. Enter your date of birth and set the second date to the cut-off date given in the notification to see your exact age on that day.
How age is calculated
We count full years first, then full months, then the remaining days. When the day of the month has not yet been reached, we borrow the correct number of days from the previous month, so results stay accurate in February and in leap years.
