Use the calendar set menu in Fantastical's mini window or full calendar window to change your active calendar set. Check or uncheck calendars on the right to determine their visibility when the set is selected. Select a set in the list and its available calendars will be displayed in the right pane. To add a new set, use the + button at the bottom of the left pane. Check or uncheck calendars in the list as desired, or begin by adding a new set right away. When first opened, there is a Calendar Set called 'My Calendar Set' ready for you. Calendar sets allow you to create different collections of calendars and quickly switch between them, allowing you to view only what's pertinent at any given time. Fantastical goes beyond just allowing you to choose which calendars are visible by offering calendar sets.
