Age Calculator

How to use the Age Calculator

1. Enter the date of birth.
2. The second date defaults to today; change it to find age on any other date.
3. Press Calculate.

Every field is checked before calculating: if a value is missing or out of range, the field is highlighted with a message explaining what to fix. The example results shown when the page loads use the default values in the form.

Formula and method

Age is counted the way people normally state it: whole years first, then whole months, then the remaining days. The calculator finds the largest number of whole months that fit between the two dates (a day that does not exist in a shorter month, such as the 31st, is moved to the last day of that month), and the days left over are counted from that point.

Total days = (Date − Date of birth) in days

Next birthday is the first anniversary of the birth date after the chosen date.
