In the Calendar app, you can set up multiple calendars to keep track of different kinds of events. You can keep track of all your events and appointments in one calendar, but additional calendars are easy to set up and a great way to stay organized.
You can also subscribe to an iCalendar (.ics) calendar by tapping a link to it.
You can unsubscribe from a calendar you’re subscribed to. When you unsubscribe, you can also report the calendar as junk.
Go to the Calendar app on your iPad.
To view multiple calendars, tap next to a calendar.
Turn Event Alerts on or off.
Tap Done.
Tap the event, tap Calendar, then select a calendar to move the event to.
