Remove end time for just ONE event

Site URL: https://www.clevelandcello.com/events-1

My apologies if this has been answered somewhere: I could find variants on this topic, but not this PRECISE topic.

I list several events on my website.  For just ONE of them I need to remove the end time.  (My current template refuses to let me specify only a start time: the best I can do is something nonsensical like "2:00pm-2:00pm.")  I found from another request thread the code to remove ALL end times from ALL events (which the solution I have temporarily applied).  But I need to remove it from just ONE event, to get something like "2:00pm."  (Otherwise I will have to add text in event descriptions for all the events that DO have an end time, stating their end times.  I can do this, but would love to be able to just delete end times from the very few events I ever have which do not have end times, rather than manually entering end times for the very many events I have that do have end times.)  I saw a reply that advised how to do this using some sort of tag thing (can you tell I am an utter noob?!) but I did not understand the answer.  Any advice from someone who can explain it to me like I am a slightly-slow 5-year-old?  I do know how to copy and paste code into the Custom  CSS place, etc., but that is about it.  

(Man, I signed up with SquareSpace because I was told it was simple and flexible.  But not flexible enough to let me NOT input an end time!  *sigh*)

Hi,

We can do this. Which event you want to remove end time?

Thank you so much for responding!  I already used a code script (is that the right phrase?) which removed ALL end times, which is an adequate solution for us.  It is this code, I think:

span.event-datetime-divider, time.event-time-localized-end {
  display: none;
}

How would you modify it to address just individual events?

Each event will have a different ID, so you need to let me know which event you want to remove end time, I can help easier

I am sorry I did not check earlier, and see your reply!  Thank you for helping me.  As I mentioned in my October 17 message, I have installed some code which takes away ALL end times of ALL events.  If I delete this code ALL events get end times again.  So I am trying to turn off an end time for ONE event.  Here is one:

Right now its end time is off, because the code is active.  

Thanks,  GM

Many thanks!  I will try this out!
