A Calendar Set lets you choose which calendars or reminders to show or hide in each view.
Each view (like Monthly, Weekly, Tasks) can have its own visibility settings.
You can change the visible calendars in any view:
▶️ Method 1: Swipe from the right edge
▶️ Method 2: Use the menu
Go to the upper-right menu > Calendar and Reminder List
Each view remembers its own setup.
By default, widgets follow the Monthly View's Calendar Set.
To customize which calendars appear in each widget, use the Widget Calendar Set (Premium only).
▶️ ① In the app
Go to: Settings → Widget → Calendar Set
