Cannot unsubscribe holiday calendar that is NOT in “Subscribed” calendar list

I don’t want holiday calendar & didn’t subscribe to it.

Am I being charged for a service I didn’t order it.

next phone won’t be an iPhone.

Is Apple charging me?

Hi TigerMarc,

Thanks for connecting with us here in Apple Support Communities. While you can't delete the Holidays calendar, you do have the option to hide it. The following article will walk you through doing so: Use the Holidays calendar on iPhone - Apple Support

Use the Holidays calendar on iPhone

In the Calendar app, the Holidays calendar displays holidays based on the region set on your iPhone.

Note: The Holidays calendar is a subscription calendar. You can’t add or delete holidays, because subscription calendars can be modified only by the calendar provider.

Show or hide holidays

1. Tap Calendars at the bottom of the screen.

2. Select or deselect US Holidays (or the holiday calendar for your country or region).

Add a holiday calendar from a different region

1. Tap Calendars at the bottom of the screen.

2. Tap Add Calendar, then tap Add Holiday Calendar.

3. Tap the holiday calendar you want to subscribe to, then tap Add.

Take care.
