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: Tap 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: Tap Day, Week, or Month below the calendar.
Change the viewable time period: Tap the arrows on either side of the date above the calendar.
Go to a specific date: Tap the Action pop-up menu in the bottom-left corner, then choose Go to Date. Type or select a date, then tap OK.
Go to the current day (if it’s not visible): Tap “Go to today” below the calendar. If you don’t see “Go to today,” tap the Show Calendars button to hide the sidebar.
If the calendar is shared, your settings apply only to your view of the calendar, not to anyone else’s view.
