Need help to delete Subscribed Calendar on iphone 12pro (iOS 26.1)

I have been receiving multiple calendar spam invites. One of them even sets off the Alert tone forcing me to turn off tones for the Calendar. I think the culprit may be a US Holidays subscribed calendar that I am unable to unsubscribe or delete. When I open the circle i for information there is no option to delete it (fwiw, if I turn off Event Alerts it resets after I exit out).

The US Holidays Calendar cannot be deleted.

Go to Settings > Apps > Calendar > Accounts, and view the Accounts that show syncing with the Calendar. You can turn those off by tapping on them. A Google or Microsoft Exchange (Outlook, Hotmail) is likely going to have a synced Calendar that can be shut off.
Also review if you have any Apps that have been granted Calendar access at Settings > Privacy & Security > Calendar.

Just from some recent posts, it does appear that the Microsoft servers have been flooded again with Calendar spam, so if you have one of those mentioned accounts, then that is likely the case and stopping those accounts from syncing will resolve the problem. It had also been reported previously over at the Microsoft Support forums. Not sure if that applies to you, just an educated guess from what I have seen.

There are no apps that are granted access to my Calendar. However, listed at the top for Tuesday Nov. 11 is spam. Can I delete this? Otherwise, there are 2 calendar accounts, one for icloud and the other is for my personal email. When I selected Calendars I am asked If I want to delete from my iphone, I am not sure if I do. Any concerns turning off Mail, Contacts, Calendars and Notes?
