I live in the United States (mid-Atlantic) and have my settings set to the US. Every few days, the calendar holidays will switch to Canada, despite the setting still being set to the US. I have to switch to a third country then switch back to get the US holidays until it happens again.
It has happened on iPhone 11 and 12, so it doesn’t appear tied to the hardware.

Juan Rivera1,
It sounds like you're still having the same problem with the US Holiday Calendar switching to Canada. If you've checked to make sure your iPhone software is up to date, changed iPhone region & reinstalled the Calendar app, then we want you to follow the steps found in the Apple Support articles below:
Use iCloud calendar subscriptions
If your iCloud Contacts, Calendars, or Reminders won’t sync
Have a nice day.
It lasted a whole 11 days this time which is the longest it has stayed on US holidays. It’s back on Canada again.
