Customize a calendar on iCloud.com
You can choose how a calendar is displayed or view specific parts of a calendar (for example, a specific day or the entire month).
In Calendar on iCloud.com, do any of the following:
Show or hide the sidebar: Click the Show Calendars button below the calendar.
Show or hide calendars: Select or deselect them in the sidebar.
View one day, week, or month at a time: Click Day, Week, or Month below the calendar.
Change the viewable time period: Click the arrows on either side of the date above the calendar.
Go to a specific date: Click the Action pop-up menu in the bottom-left corner, then choose Go to Date. Type or select a date, then click OK.
Go to the current day (if it’s not visible): Click “Go to today” below the calendar.
Change the order of the calendars in the sidebar: Drag them up or down in the list. You can’t drag a calendar to a different section.
If the calendar is shared, your settings apply only to your view of the calendar, not to anyone else’s view.
