Accessing Calendar View Options
Go to Calendar. The view toggle can be seen on the upper right part of the screen.
There are three types of Calendar views available: Today, Week View and Day View. Click on the view type of your choice to toggle the selection.
Accessing Calendar View Settings
On the lower right corner of Calendar, you will see a small icon depicting gears. 
Click on the icon to bring up the Calendar View settings selector.
You can make adjustments to these settings: Calendar Start Time, Calendar End Time, and Interval. Clicking on any of these gives you a drop-down menu of available options. For Interval, there are three possible options: 15 Min, 30 Min, and Hour.
You can also change which Users' appointments are viewable on the Calendar. If you uncheck the box beside a username and click Apply Changes, that User's appointments will no longer be displayed for you on the Calendar.
For example, unchecking the box beside "Erica Boysen" will keep that User's appointments from being shown in Calendar View. Before unchecking the box, the Calendar View appears as follows:
Then the box beside user "Erica Boysen" is unchecked. Now, that user's appointments will no longer be shown in Calendar View.
Here is the Calendar View after removing the user. The user's appointments no longer appear.
Changing the Colors of Appointment Blocks
In Calendar View Settings, you can assign a color to each User. Click on the box to the right of a User's name. This opens a small pop-up selection of available color options. Click on a colored square to assign that color to the User. Click on the Apply Changes button to confirm your selection.
Then when you return to Calendar View, the User's appointment blocks will now be in the assigned color.
