    Asked by lonerider on July 05, 2014 at 03:50 AM

    At first, excuse my bad englis, I´ve learned it at school long time ago.

    And now my problem.

    Is it possible to calculate the age of a person based on her birthday?

    Thank you for your help

    Hello Lone Rider

    It is already possible to calculate the age by adding the birthdate.

    1. Add 2 datefields, one of them with default date of today:

    Then add a form calculation widget with the formula (todayfield-birthdatefield)/365:

    You can test and clone the demo form:
