Good evening Logan,
Thank you for taking the time to write back.
Before we continue, just to set expectations, I’m afraid that we’re not equipped to provide technical support for our free the Events Calendar users here in our pre-sales forum.
But, the good news is that you are still welcome to consult this forum and all our premium forums to your liking and browse it for solutions, snippets and tutorials.
We’d be more than happy to assist you at one of the following locations:
With that in mind, the file you will want to modify is called single.php and it lives in /wp-content/plugins/the-events-calendar/src/views/
Have a great day!
Geoff B.
