Display modes
You can use the calendar in one of four display modes: 4 Days, Week, Month, or List.
The List display looks a lot like the Tasks section, but it doesn’t show you all of your tasks. Instead, it shows you tasks with a deadline and when they are due.
If you need to return to older tasks from the previous week or month, or if you want to plan ahead, use the arrows on each side of Today to flip the calendar backwards or forwards. You can do this in any display mode except for List.
