You will need the Full Write Events permission to perform this action.

Find the event

You can open an event from the calendar or from the event listing:

From the calendar - go to Events > Calendar and click the event. A quick view opens on the right side of the page.
From the listing - filter for the event, then click its name or select View from the 3-dots menu.

For repeating events, you can pick any occurrence.

If you can't find the event, make sure its calendar is visible. You can show or hide calendars from the side bar.

Preview the event from the calendar

The quick view lets you check an event's key details without leaving the calendar. It shows:

Visibility - for example, Public.
Date, time, and calendar - when the event happens and which calendar it belongs to.
Booked Facilities - any rooms or resources requested for the event, with each one's type (such as Room) and request status (such as Pending). This section only appears when the event has facility requests.
Organizer(s) - each organizer's name and contact information.

Edit the event

In the quick view, click Go to Event.
On the event page, open the Actions menu in the top right and select Edit event.
Update the event details in the pop-up and save your changes.

For details on each event field, see How do I add an event?

Tip: On a repeating event, click the date next to the event title to open a calendar and jump to any other occurrence. Only dates in bold are part of the repeating schedule.
