How do I unsubscribe from a calendar (i.e. delete a calendar subscription)?

On the home screen of the device, tap Calendar.

Turn the device to portrait orientation, scroll down to Calendar and tap it.

Look for the calendar you wish to unsubscribe. If you are removing a calendar subscription, it will say Subscribed under it. This will help you identify the correct one.

If your calendar is listed under Google (or your Gmail address), please switch to removal instructions for Google Calendar.

Tap on the icon beside the calendar yuo wish to remove.

Scroll down and tap Delete Calendar.

Tap Delete Calendar.
