Update Your Calendar

If holidays are still not showing, it might be due to an outdated calendar. Microsoft regularly updates its calendar with new holidays, and you can manually update yours to ensure you have the latest list.

Troubleshoot Further Issues

If updating your calendar and checking your settings didn't resolve the issue, there might be other factors at play.

Sometimes, third-party add-ins or extensions can interfere with Microsoft Calendar's functionality. Try disabling these temporarily to see if they're causing the problem.

Disable Add-ins and Extensions

1. In 'Settings', click on 'Manage add-ins'.

2. Turn off any active add-ins and see if that resolves the issue.

Repair or Reset Your Calendar

If all else fails, you can try resetting or repairing your calendar.

1. In 'Settings', click on 'Manage calendars', then click on 'Repair' or 'Reset' next to your calendar.

If you've tried all these steps and are still having trouble, it might be a good idea to reach out to Microsoft Support for further assistance. Happy calendaring!
