    Age calculator does not seem to work with Birthdate picker

    Asked by pbwithew on June 09, 2014 at 11:17 PM

    I've looked at your helpful form where you calculate age based on a birthdate that is input using the Date/Time tool (http://www.jotform.com/answers/388255-How-to-Automatically-Calculate-Age). However, when I use the Birthdate Picker to input a birthdate, the formula does not work.

    An additional question -- how does JotForm represent a date? For example, is it possible to make just one calculated field for age that would look something like:  (#####-{birthdate})/365.25, where ##### is JotForm's representation of today's date.

    Hello,

    Thank you for contacting us.

    About the Birth Date picker let me forward and ask our level 2 about this as I'm not sure if DateTime and Birth Date Picker should both work. We'll notify you in this thread for updates.

    An additional question -- how does JotForm represent a date? 

    That is not possible as you cannot select the Age field when adding to calculation that is why you need to make an additional calculation to compute for Days / 360.
