Outlook: How To Delete Duplicated Holidays

Posted November 6, 2007 by Rob Rogers in Microsoft Outlook

If you inadvertently add the same holidays to your Calendar more than once, it can not only look rather messy, but also take attention away from other important events you might have on those days. While you could remove them by taking the time to delete each one, there is a much quicker method to force your Calendar to celebrate the holidays only once per event.

1. Go to Calendar.

2. Click View, mouseover Current View and select Events. This will provide a list of all events in your calendar.

3. Right-click a column header and select Field Chooser from the resulting menu.

4. In the Field Chooser box, use the dropdown and select Date/Time fields.

5. Select Created.

6. Drag Created to the Column Headers to add it to the list. Close the Field Chooser box.

7. Now click on the newly added column header (Created). This will sort all of your events by the date that they were added to your Calendar.

8. Find the group of holidays you wish to remove.

9. Select the first holiday in the list that is to be deleted.

10. Scroll down to the last holiday that is to be deleted. Hold down the Shift key and select this holiday. This will highlight all of the holidays that you are going to remove.

11. Press the Delete key. The duplicate holidays will be removed from the Calendar.

12. Click View, mouseover Current View and select Day/Week/Month to return the Calendar to the normal view.

Your Calendar should now only display one set of holidays.

    Perfect Instructions – You should write a book!

  • Kojak

    OMG, where have you been all my life? You are my hero!

    Not only was the information spot on, it was presented in a way that even a dummy like me was able to understand the instructions and remove the extra holidays from my Outlook Calendar.

    Thank you for being such a great teacher. And I agree you should write a book.

  • fred

    this works only if the events were created on different days. in my case when I use the instructions above I found all my events were created on the same day for all the main holidays and for several years. I don’t know what to do – maybe just delete ALL event and start over???

    • Wayne

      I found that there was a “category” column in view * events and when I clicked on that it put all the holidays together. I then reinstalled the holidays using tools * calendar options * add holidays. This fixed the problem I was attacking, which for some reason my calendar had the wrong dates for Memorial Day.

    It’s Nov. 2012, and I’m so glad these instructions are still posted! I Googled the duplicate holidays problem and selected the first three results — yours were the best. Even several versions of Outlook later, the instructions were easy enough to follow along. Thanks so much!

  • Judemon

    Back to work after Christmas holidays, public holidays had disappeared in Outlook (among other snags) so I impatiently re-imported them. I assume our server eventually caught up with things and I ended up with duplicates, annoying me no end! Over 10 years worth of duplicates, so I am very appreciative of this tip, thanks!!
