SharePoint 2013 enable support tracking capabilities, and then clearly display the departure/leave time of team members.
You could track the leaving time of team members by creating a view of Calendar type(or choose create a Calendar List directly).
Follow these steps:
1.Create a List that stored the Leaving reports
2.Click Create View menu, then select Calendar View
3.The View be named TimeShell, and then set time intervals, etc.
4.Set "Show items only when the following is true" so that Issue Status (or other that your named ) "is equal to" "Approved" (or whatever you chose to call it).
