About the Age Calculator
Enter a date of birth and this calculator shows the age in completed years as of today — the number you give on forms for eligibility, insurance and admissions. The age increases on the birthday itself.
It answers questions such as how old someone born on 15 June 1995 is today.
Things to keep in mind
- The result is in completed years only; it does not show extra months or days.
- Some documents use age as on a particular date, such as the closing date of an application. For that, count the years yourself to that date.
- A person born on 29 February has a birthday on 28 February or 1 March in non-leap years, depending on the rule used.
