The menu located on the left-hand side is interactive to either allow the user to view the day or add an event to the calendar. 



If view day is clicked the user will be taken to their calendar for that day. They can always change the setting from My Calendar to Entire CAC Calendar at the top left-hand side to see the CAC calendar for the day. 





If add event is clicked the Add New Event area will show allowing the user to schedule an event to add to the calendar.
