How the age calculator works
This age calculator answers the everyday question "how old am I?" precisely. It takes your birth date and today's date and works out the exact gap in years, months and days — following the real calendar, so leap years and months of different lengths are all handled correctly.
Beyond your age, it shows the total number of days and hours you have been alive, counted from midnight on the day you were born, and how many days remain until your next birthday. It is handy for filling in forms, settling a friendly argument, or simply seeing your life in numbers.
