How Do I Have a Field Display a Date Which Is a Specified Number of Days Prior to That Selected in a Date Field?

Yes that's possible. You can achieve it by creating conditions (Example form: https://www.jotform.com/form-templates/calculate-number-of-days, feel free to clone it so you can check the conditions) or by using this widget. http://widgets.jotform.com/widget/dates_difference

Then use a form calculation widget to get the result. Example:

Hope this helps!

Hi Lauren,

In addition to my learned colleague's solution, please see this form which uses another method. If you were to clone it and examine its saved condition, you'll see the following:

To construct the expression seen in the work area above, I clicked the button with the ellipses (...) and then clicked the dateString() method:

Then I clicked the Back button (in the screenshot above), clicked between the parentheses to place the insertion point there and clicked Add Field and inserted the demo date field:

Then it was just a matter of typing -7 after it to output a date seven (7) days earlier.

If any of this is unclear, please inform us.

Cheers
