Hi Nataliya,
Thanks for reaching out to us! We really appreciate your support in using Events Calendar Pro!
To answer your question, you can remove the entire line (date and time) easily with CSS:
.tribe-events-duration { display: none; }
However, removing <i>only</i> the time would require more advanced customizations, as would adding the day name. You can take a look at our Themer’s Guide, which offers information on how to make customizations to our products, or contact one of our recommended developers if you need help implementing a customization.
If this is an option you would like to see added in the future, you can also suggest it in our Feature Ideas forum for other users to vote on. If an idea gets enough votes, we may consider implementing it in the future.
I hope that helps! Please note that as we do not offer support in our pre-sales forum, I am going to go ahead and close this thread. As a premium user, you have access to our premium support forum, which is where we provide support for current customers. If you need any further support, please feel free to open up a new thread there, and we’ll be happy to help you!
