Is it possible to custom Event Date format?
You can add a new date/time format by going to Administration > Configuration > Regional and Language > Date and Time. In the upper right corner of the screen you see two tabs: Types &amp; Formats. First go to Formats and add your desired date format there (according to PHP date formatting). In your case, this will probably be something like

D, M j, Y - g:i a


Next, you go to Types and create a new date type. You can assign your custom date format to this new date type.
