In Outlook 2013 there are a few options available for calendars.

Depending on your view it may appear as a button or as a small icon (see screenshots below for examples).

Listed on the left will be all the calendars that you currently have shared access to.
Calendar view options
(All the screenshots below are in thumbnail view, click on those you wish to see more clearly.)
Looking at your own calendar, you will see there are a few view options to help you. In the following screenshots we have added a number of appointments to show how they appear in the different views. For any appointments scheduled for the whole day, you will see that the background is shaded accordingly to whether it is a Free/Tentative/Busy/Out of Office appointment.
The other view available is Schedule view, this is useful when you have multiple calendars open. See viewing multiple calendars to see how it compares to other views.
