If you don't have an answer for one of the questions type 0 and move on. Example: You were born on March 23, 2018 at 2:30 PM What year were you born?: 2018 What month were you born?: 3 What day of the month were you born on?: 23 What hour of the day were you born?: 14 (Use Military Time) What minute of the hour were you born?: 30 Stats: The approximations given are on average 2 days off (from my research). This is due to the fact that months aren't all the same length. Though 2 days of the real answer isn't that bad in my opinion. Uses: This calculator is made to be used for approximating the age of a person, although it can approximate how old anything is (e.g. the USA)
