How the age calculator works

Your age is counted the way people say it: whole years first, then whole months, then the leftover days. If you were born on the 31st and a month is shorter, the month ends on its last day.

Totals in weeks, days, hours and minutes count every calendar day between the two dates, leap days included. People born on February 29 celebrate on February 28 in common years here.
