About this tool
How exact age is calculated
Age is counted in completed years, then completed months, then remaining days, the same way it is calculated for official forms. When the day of the month has not been reached yet, the calculator borrows the number of days from the previous month, so results stay correct across months of different lengths and leap years.
Calculating age on a specific date is useful for school admissions, job applications, sports categories and visa forms, which often set an age limit on a cut-off date rather than today.
