How to delete Calendar subscriptions on iPhone?

How to remove a calendar on your iPhone in earlier versions of iOS

1. Open the Calendar app.
2. At the bottom of the screen, tap Calendars.
3. Look for a calendar that you don't recognize. Tap the More Info button  next to that calendar, then scroll down and tap Delete Calendar.

If this doesn't fix the issue, delete the calendar subscription in Settings:

1. Open the Settings app.
2. Tap Calendar > Accounts. Or if you use iOS 13, tap Passwords & Accounts > Accounts instead.
3. Tap Subscribed Calendars.
4. Look for a calendar that you don't recognize. Tap it, then tap Delete Account.

The suggestion is a little vague.

OK - I will provide the last detail. After you tapped “Calendars” in the bottom center as I suggested above, uncheck the calendar(s) you no longer wish to see.

Open the Calendar app. Tap "Calendars" in the bottom center. Remove calendars from there you no longer want.

As Axel Foley said above:

”Tap the More Info button  next to that calendar, then scroll down and tap Delete Calendar.”
