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

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.
