I'm using Drupal 8.4 Webform Module. I selected the Date element (not Date/time). In the Webform Date Settings, I'm using date picker, Medium date - D, m/d/Y (Mon, 11/27/17). (I also tried Custom, D, M j, Y.
I'm using this field in a View, Format = Default medium date and this is what I get, Thu, 12/14/2017 - 00:009:00 AMFri, 12/15/2017 - 00:005:00 PM . How do I remove the trailing zeros?
Go to 'yoursite/admin/config/regional/date-time' and click the button, '+ Add Format' to add a new date format.
Enter a name for this new format and add your date format in the Format string box.
Example: D, M j, Y will output Fri, Dec 22, 2017. Click Add Format
Go to your Webform > build and select the date element you want format with your new date format. In the Advanced tab, select your new date format in the SUBMISSION DISPLAY > SINGLE ITEM > ITEM FORMAT box and save.
You should also be able to select the new date format in Views.
Its best to clear the cache at yoursite/admin/config/development/performance
