Is there a way to change just the title of my 1-on-1 calendar?

Hey @Bill_C -- of course!

All you have to do is head into your event type settings > click “event details” at the top of the editor > update the “event name” field of the event there > click “save and close” at the bottom to apply it. 

This will apply to all future bookings, but will not change the title of bookings already made (even if they are still upcoming).

Here’s a short video going over the steps, for you: 

I hope this helps!
