The Calendar section contains a secondary menu and three panels, which provides a Calendar list; Preview pane with a Monthly, Weekly, or Daily view; and a Task list.
The Secondary menu displays the current month’s calendar, as well as a list of your created calendars and shared calendars that you have subscribed to.
Event Display List
The Event display list provides details for all events scheduled for that day. Changing the day inside the Secondary Menu calendar will update your Event display list. This allows you see what events are coming up over the next few days.
