Hey there, calendar warriors! Holiday Little Assistant here, your go-to pal for all things holidays and tech headaches. Recently, I’ve been getting flooded with questions like, *”Why is Christmas showing up three times in my Outlook calendar?”* or *”How do I stop my calendar from spamming me with duplicate holidays?”* If you’re nodding along, don’t worry—you’re not alone. Let’s dive into this mess and clean it up for good!

Why Does Outlook Create Duplicate Holidays?

First, let’s understand the *why* before fixing the *how*. Duplicate holidays usually sneak into your calendar in a few ways:
– **Multiple Subscriptions**: You might’ve added holiday calendars from different sources (like Outlook’s built-in list *and* an imported ICS file).
– **Sync Glitches**: Sometimes, syncing across devices (phone, desktop, etc.) goes haywire and creates doubles.
– **Manual Adds**: Accidentally adding holidays manually when they already exist. Oops!

Now, let’s tackle the fixes—no tech degree required.

Step-by-Step: Removing Duplicate Holidays in Outlook

**Method 1: Delete the Built-in Holiday Calendar** (For Outlook Desktop)
1. Open Outlook and go to **File > Options > Calendar**.
2. Under “Holidays,” click **Add Holidays**.
3. Uncheck your country’s holiday set (e.g., “United States”) and hit **OK**. Boom—gone!
4. *Pro Tip*: Re-add a clean version later if needed.

**Method 2: Manually Nuke the Duplicates** (For Stubborn Ones)
1. Switch your calendar to **List View** (under the “View” tab) to see all events at once.
2. Sort by “Subject” to group duplicates (e.g., all “New Year’s Day” entries).
3. Right-click the extras and select **Delete**. *Protip*: Hold **Ctrl** to select multiple at once!

**Method 3: Sync Fixes for Mobile/Web**
– **Outlook Mobile**: Go to **Settings > Calendar > Holiday Calendar** and toggle it off.
– **Outlook Web**: Click the gear icon > **View all Outlook settings > Calendar > Shared calendars** and remove extras.

**Bonus**: Use tools like *”Calendar Cleaner”* add-ins to automate this if you’re dealing with *hundreds* of dupes.

How to Prevent Future Duplicate Holidays

Nobody wants a repeat of this chaos. Here’s how to stay clean:
– **Pick One Source**: Stick to *either* Outlook’s built-in holidays *or* a trusted ICS feed (like from timeanddate.com).
– **Audit Annually**: Before New Year’s, peek at your calendar for duplicates—it’s easier to fix early.
– **Sync Carefully**: If you use multiple devices, ensure calendar settings match across all of them.

Alright, friends—that’s the scoop! Whether you’re drowning in duplicate Thanksgivings or just want a tidier schedule, these steps should save your sanity. Remember, your calendar should work *for* you, not against you.
