Hide or Remove the Extra Holiday Calendar

The easiest way to resolve duplicate holidays is by managing the calendar pane to either temporarily hide or permanently delete the redundant holiday calendar.

Duplicate holiday entries usually appear because multiple country or regional holiday calendars have been added to your Outlook account. Managing the calendar pane allows you to clean up your view without deleting individual events manually.

Open Outlook Calendar

Launch Microsoft Outlook and navigate to the Calendar view by clicking the calendar icon at the bottom left of the screen.

Locate the Calendar Pane

Look at the left-hand navigation pane to review the list of all active calendars under 'My Calendars' or 'Other Calendars'.

Hide the Duplicate Calendar

To temporarily hide the duplicates, simply uncheck the box next to the extra holiday calendar. The events will instantly disappear from your main view.

Delete the Redundant Calendar

If you want to permanently remove it, right-click the name of the redundant holiday calendar and select 'Delete Calendar' from the context menu.

Hide or Remove the Extra Holiday Calendar

Clean Schedule: By hiding or deleting the entire redundant calendar, your schedule remains clean while keeping your personal appointments completely safe.

Solution 2

Delete Individual Duplicate Holiday Events

If the duplicates are contained within a single calendar, you can switch to a list view to group and delete specific holiday entries manually.

Frequently Asked Questions

Why do I have duplicate holidays in my Outlook Calendar?

This usually occurs if you have added the same country's holidays multiple times through the calendar options, or if you imported overlapping regional holiday calendars into your account.

Will deleting a holiday calendar remove my personal appointments?

No. Deleting a specific holiday calendar only removes the events contained within that particular calendar. Your personal appointments stored in your primary calendar will remain unaffected.

How do I add holidays back if I accidentally delete them?

You can restore holidays by going to File > Options > Calendar. Under the Calendar options section, click on 'Add Holidays', select the countries you want, and click OK.

Can I hide holidays without deleting them completely?

Yes. In the calendar navigation pane on the left side of your screen, simply uncheck the box next to the holiday calendar you wish to hide. Checking the box again will bring the holidays back into view.
