Open the window
Choose Window → Calendar Window or press Command-0. The window is designed for planning that needs more room than the menu bar panel.

Week on Week
Week on Week is off until you switch it on, in Settings → Appearance → Week on Week view. It is opt-in so the view switcher stays six wide for everyone who does not plan by weekday.
It lines up one weekday across seven weeks, a week per column — seven Mondays side by side — so a recurring commitment, a gap, or a steadily filling afternoon stands out in a way the ordinary Week view cannot show. Slide the row a week at a time with a swipe or the arrow buttons.
A second setting appears once it is on: Selected week, which decides where the week you are looking at sits in the row — First column, Middle column or Last column. Middle gives you weeks either side of the one you care about; Last turns the view into a run-up.
Switched on, it joins the toolbar switcher and the View menu like any other view, and its Command-7 shortcut is re-recordable with the rest of them.
Use the sidebar and inspector
The agenda sidebar keeps upcoming events and reminders beside the current view. Select an event to open its details in the inspector, where supported fields can be edited in place. Toggle the sidebar with Control-Command-S and details with Control-Command-I.
Navigate and edit
Select a time or day to create an item. Drag timed events to move them and resize their edges in 15-minute steps. Month, Quarter and Year preserve spanning multi-day events as bars rather than unrelated dots.
Search filters the visible calendar. Smart Filters can save the query, selected calendars, rules and view as a reusable workspace.
