The Activity Calendar is used to provide you and your users an effortless way to keep track of all your activities by day or week. 

You can access your calendar by clicking the vertical ellipses (⋮) on your Activities App and selecting Calendar. 

You can also click View Activity Calendar on your Activities List screen. 

By default, the calendar screen displays the day view for the current day, and only displays the activities assigned to the user logged in.
