Calendar events are the actual event instances for the room. These have a time zone defined and a start and stop time for the event.
You can also include additional metadata for E2H in the description of the event, such as:
•{setup:xx} = this event includes a setup time of xx minutes in advance of the start of the event
•{teardown:xx} = this event includes a teardown time of xx minutes after the end time of the event
•{exclude:true} = exclude the event from showing in E2H
Note: You can separate multiple items by comma. E.g. {setup:5, teardown:0}
