How Is Your Age Calculated?
Age is usually expressed as the calendar difference between a person’s date of birth and a selected date. The calculator compares the year, month, and day values to determine completed years, remaining months, and days. Because calendar months have different lengths and leap years add an extra day to February, calendar age is not calculated by simply dividing the total number of days by 365.
