Hi Aaron,
Thanks for reaching out! At the moment, we don’t offer any built-in options for changing the display of our event date pickers. Any changes to the existing date picker format would need to be made via changes and/or overrides to the existing jQuery and CSS. I’m sorry to disappoint! If you’re interested in seeing options for styling the date pickers added to a future plugin release, I’d suggest submitting your idea to our UserVoice forum, where it can be voted on by other users.
Again, I’m sorry to disappoint! Thanks again, and let us know if you should have any other questions!
