’Tis the holiday season, and you’re probably looking to transform your game into a winter wonderland filled with festive activities and Christmas-themed celebrations. To make that happen, you need Sims 4 holiday mods.

These mods add immersive seasonal moments to your game, bringing richer celebrations, snowy realism, new traditions, and cozy family activities that enhance every part of winter gameplay.

Below, I’ve curated the best Sims 4 holiday mods to elevate your December experience. Let’s dive in!

Note: Most of the holiday and winter mods in this list require the Seasons expansion pack to function correctly. Only a few options work with the Base Game alone. Always check a mod’s requirements before installing to make sure it’s compatible with your setup.

More Premade Holidays – Adeepindigo

Download: More Premade Holidays

More Premade Holidays adds dozens of ready-made seasonal celebrations to your in-game calendar. This gives your worlds a fuller festive atmosphere and eliminates the need to add custom holidays manually.

With each event, there are preset traditions, icons, and moodlets, offering a wide range of themes such as Christmas, winter gatherings, romantic dates, cultural festivities, and family-oriented milestones. This mod blends naturally with the Sims 4 Seasons system, keeping your calendar varied throughout the year.

Features include:

• A large selection of premade holidays covering winter, Christmas, cultural, romantic, and family events.
• Fully set traditions with activities already assigned for quick gameplay.
• Unique icons and moodlets for better holiday identification.
• Balanced scheduling to avoid overcrowding your calendar.
• Built-in autonomy tuning so Sims participate in holiday activities smoothly.

Compatibility:

This mod is fully base game compatible. But you can also use it alongside the Seasons expansion pack and other calendar or holiday-related mods.

It’s stable with recent game patches and updates as long as the script file is installed correctly. It also functions alongside custom holidays you add manually, allowing you to mix and match seasonal experiences.

More Holiday Traditions -MSQSIMS

Download: More Holiday Traditions

More Holiday Traditions expands your game with 49 additional traditions you can mix and match to design custom holidays that fit any theme, season, or playstyle. Each tradition introduces its own activity, moodlet, and gameplay focus. This makes it easier to tailor celebrations for family saves, cultural events, winter gameplay, or niche storytelling.

The mod supports selective installation, so you can add only the traditions you want without overloading your calendar.

Features include:

• 49 new selectable traditions covering family activities, cultural events, creative hobbies, winter themes, and social interactions.
• Flexible installation with each tradition provided as an individual package for full customization.
• Pre-built icons and moodlets that help distinguish each tradition.
• Smooth integration with EA’s Seasons calendar, allowing custom holidays built from scratch.
• Full compatibility with More Premade Holidays, enabling both mods to run side by side.

Compatibility:

Some of the traditions require packs like Seasons, while some are compatible with the base game. To get the most out of this mod, install most DLCs, as several traditions pull interactions from specific packs.

The mod was created with Game Version 1.84.197.1030 and remains compatible with Patch 1.108.335.1020 (July 26, 2024). If the traditions fail to appear in an existing save, test them in a new save to resolve the issue.

More and Better Holidays – ZelKat13

Download: More and Better Holidays

Created in May 2025, this is one of the newest Sims 4 holiday mods to add to your seasonal gameplay. The mod expands the default seasonal calendar by adding new holidays and refining EA’s existing ones. This, in turn, creates a rich and more engaging experience when starting fresh save files.

The mod generates an improved holiday schedule based on your chosen season length, e.g., 7, 14, or 28 days. So each new game begins with a full set of meaningful events rather than the same four standard holidays.

I highly recommend this mod to players who frequently create new saves and want a ready-made seasonal structure.

Features include:

• Expanded sets of holidays for all season lengths (7, 14, and 28 days).
• Tweaked versions of the default EA holidays for smoother gameplay.
• Optional versions designed for Even Longer Seasons by Rasmus Massie and the 21-Day Seasons mod by LittleMsSam.
• Automatic holiday generation for new save files, eliminating repetitive setup.
• English and Spanish language support.
• Thoughtful calendar placement aligned with the Seasons system to prevent holiday deletion.

Compatibility:

You need the Seasons expansion pack and the Base Game. It only works with new save files, as holidays are generated at save creation. When using the Rasmus compatible versions, holidays beyond week eight may not appear due to a hard-coded limit in the game’s calendar system, leading to several empty weeks in 63- or 84-day seasons.

Make sure this mod loads before any season-length mods. Otherwise, the game will revert to default holidays. Uninstalling may remove the added holidays and doesn’t restore EA’s original set.

Recommended Add-ons:

The creator suggests pairing this mod with Make Hidden Holiday Traditions Selectable, Surprise Holidays Be Gone, Festival Notification Rework, and several holiday tradition overhauls for fuller representation and improved event behavior.

HELPFUL TIP: Before installing any holiday mods, make sure your game is updated to the latest patch. Outdated mods can cause glitches, missing interactions, or broken holiday events.

Special Holidays – KawaiiStacie

Download: Special Holidays

This is one of the best Sims 4 holiday mods you can add to your gameplay. It introduces a curated set of seasonal events to your calendar and adds eight new holidays and three surprise replacements for everyday EA events.

The mod focuses on variety, emotional storytelling, and family-centered gameplay. So, you can use it for richer holiday storytelling. You can also edit every holiday in-game to adjust activities, traditions, and moodlets to fit your preferred playstyle.

Features include:

• Eight new holidays covering summer fun, family bonding, wellness activities, spring celebrations, spooky gameplay, environmental themes, and remembrance days.
• Three surprise holidays that replace Pirate Day, Battle Royale, and Prank Day with more meaningful alternatives, such as Pizza Day, Kids Day, and Beer Day.
• Fully editable entries so you can customize traditions, icons, and calendar placement.
• Strong focus on family interaction, seasonal immersion, and culturally neutral celebrations that fit any save.

Compatibility:

The mod requires the Seasons expansion and works only on new save files or newly created households, as existing saves already load their calendars.

It conflicts with other premade holiday mods because it overrides the seasonal calendar, so only one holiday overhaul should be installed at a time. You can modify all holidays in-game without affecting stability, making the mod flexible for long-term saves.

Helpful Tip: If you’re new to mods, place all holiday mod files in your Mods folder and enable Script Mods in the game settings. Restart your game after installation to activate everything.

School Holidays – LittleMsSam

Download: School Holidays

If you want to make your kid’s school calendar more realistic, download the School Holidays mod. It adds a natural break system for children and teens, giving them occasional days off from school.

The mod pack introduces short, randomized holiday periods that simulate real-life school breaks and adds more variety to weekday gameplay. When a holiday triggers, every child and teen in the household receives a holiday buff, letting them skip school until the break ends.

Features include:

• Randomized school holidays lasting one, three, or five days.
• A default 2% chance for a holiday to trigger at wake-up time.
• Household-wide breaks where all children and teens share the same holiday duration.
• A clear “On Holiday” label in the UI during active breaks.
• Automatic return to the normal school schedule once the buff wears off.
• A natural, low-maintenance way to add realism to family gameplay without editing the Seasons calendar.

Optional Addons:

There are four optional add-ons, which increase the base holiday chance to 4%, 6%, 8%, or 10%. Only install one add-on at a time, and get lower percentages for larger households to avoid constant breaks.

Compatibility:

The mod works independently from the holiday calendar, so it fits smoothly into all saves and doesn’t require new save files. It’s available in multiple languages, including English, German, Spanish, Danish, Chinese, Swedish, Dutch, Polish, and Italian.

If buffs are removed through cheats or external mods, the current holiday period will end immediately.

Surprise Holidays Be Gone

Download: Surprise Holidays Be Gone

Surprise Holidays were fun at first with the introduction of the Seasons EP, but they quickly got annoying. This mod removes all randomly generated surprise holidays introduced with the Seasons expansion to keep your calendar clean and predictable throughout the year.

Instead of repeatedly deleting unwanted events like Pirate Day or Prank Day each time they appear, the mod disables them entirely so they never load into your save. This is a simple quality-of-life fix for players who prefer full control over their calendar and custom holiday schedule.

Features include:

• Complete removal of all EA surprise holidays from the calendar.
• Individual package files for each holiday, allowing you to disable specific ones or remove them all at once.
• Clean, conflict-free calendars that no longer auto-populate with unwanted events.
• Smooth compatibility with Make Hidden Traditions Selectable, letting you keep the traditions while removing the surprise holidays themselves.
• A lightweight mod that requires minimal updates and stays stable across patches.

Compatibility:

The mod is compatible with the September 18, 2025, Adventure Awaits patch. It also overrides resources tied to all premade surprise holidays (Pirate Day, Lottery, Discount Day, Battle Royale, TV Premiere, Night on the Town, Skill Day, and Prank Day).

Any other mod that edits the same resources will conflict, so avoid them. The mod works in all saves and doesn’t require a new save file.

Disclaimer: Always download mods from trusted creators and keep them updated. Some holiday mods may conflict with older script files or outdated versions of The Sims 4.

Not Sad About Holidays

Download: Not Sad About Holidays

Not Sad About Holidays removes the unnecessary negative moodlets Sims receive when they fail to complete trivial holidays like Talk Like a Pirate Day or the TV Season Premiere. Your Sims won’t become tense, sad, or dramatic over events with little gameplay impact.

Instead, they’ll remain neutral, allowing you to focus on meaningful holidays you actually want to celebrate. This is one of the best Sims 4 holiday mods for players who customize their calendars, disable surprise holidays, or want more realistic Sim reactions.

Features include:

• Removes negative moodlets tied to minor or unwanted holidays.
• Keeps Sims from reacting emotionally to incomplete or ignored events.
• Reduces calendar-related clutter by eliminating unnecessary mood swings.
• Allows important holidays (custom or EA) to stand out without noise from lesser events.
• Works well alongside holiday overhaul mods for cleaner, more intentional gameplay.

Compatibility:

The mod requires Seasons and the Lot 51 Core Library. It pairs smoothly with Surprise Holidays Be Gone and similar mods, as it targets moodlet behavior rather than holiday generation.

Since the mod focuses only on reaction tuning, it remains lightweight and stable across updates unless EA changes moodlet structures.

Snow But Better

Download: Snow But Better

Snow But Better is among the best Sims 4 holiday mods you can add to your winter gameplay. It replaces EA’s default snow textures with a more realistic, frosty visual overhaul designed to improve winter immersion across your worlds.

The mod redraws the game’s snow, frost, and ice surfaces to remove the overly bright, plastic-like appearance and replaces this with softer, colder, and more natural textures. It also fixes common visual issues, such as patchy grass showing through winter terrain and overly bright icicles that clash with realistic lighting.

Features include:

• Completely reworked terrain snow textures for a detailed, natural winter look.
• Enhanced frosted windows and glass with sharper, more realistic frost patterns.
• A fix for green grass patches that appear through snow in winter worlds.
• Replaced icicle textures that reduce glare and blend better with cold-weather lighting.
• Improved road surfaces with updated bump maps for added realism.
• An override-based design that updates EA’s textures directly for seamless integration.

Compatibility:

The mod requires Seasons and works with Patch 1.67, 1.69, and all versions up to modern builds that include seasonal weather. Because it overrides EA’s snow textures, it will conflict with any other snow replacement or terrain overhaul that edits the same files.

The mod functions only as a visual replacer and doesn’t affect gameplay. Version 2 is planned to include script-based enhancements for expanded snowy effects, but Version 1 remains stable for visual improvements.

Urban Thanksgiving Social Interactions – JayESims x Jaye Hinson

Download: Urban Thanksgiving Social Interactions

Urban Thanksgiving Social Interactions introduces a set of conversational options designed to recreate the humor, drama, and warmth of real family gatherings. The mod adds thirteen themed interactions to capture the dynamics of modern Thanksgiving traditions. This turns any household meal into a lively social event.

Each interaction comes with its own custom buff and dialogue, giving Sims more personality, family flavor, and reactive depth during holiday gameplay.

Features include:

• Thirteen new Thanksgiving-themed social interactions, such as asking who’s saying grace, checking on mac and cheese duty, sharing embarrassing family stories, and going on a “walk” with cousins. All these keep you in a thankful spirit.
• Thirteen unique buffs tied to each interaction, adding personality shifts, mood context, and seasonal atmosphere.
• Custom notification text and dialogue that reflect modern family humor and conversational nuance.
• The mod is designed to enhance storytelling, group meals, and family holiday scenes with more realistic interaction flow.
• You get an optional user-directed gameplay mode where Sims only use these interactions when prompted.

Compatibility:

The mod is fully Base Game compatible and doesn’t require any expansion packs. It integrates smoothly with existing social tuning and does not override default holiday interactions. Because it focuses on social menus and buffs rather than calendar systems, it works alongside all holiday overhaul mods and seasonal gameplay additions.

Spooky Spirit Tradition Overhaul

Download: Spooky Spirit Tradition Overhaul

For those who love Halloween and want to celebrate the holiday in-game, get the Spooky Spirit Tradition Overhaul. It expands the Spooky Spirit holiday tradition with a wide range of new activities drawn from modern expansion packs, game packs, and stuff packs.

Since the default options for this tradition are limited, this mod broadens the activity pool to include horror movies, séances, crypt exploration, paranormal interactions, and occult gameplay. All these that better match real Halloween-inspired traditions.

Features include:

• Dozens of new thematic activities sourced from packs like Movie Hangout, Jungle Adventure, Realm of Magic, Paranormal Stuff, High School Years, Growing Together, Crystal Creations, and Life and Death.
• Expanded holiday behaviors covering horror film screenings, séances, skeleton pranks, haunted pier attractions, ghost stories, urban myths, Grim Reaper interactions, crypt exploration, tarot readings, and more.
• Full compatibility with EA’s original Spooky Spirit activities, which remain available and unchanged.
• This mod has been updated for the latest Life and Death expansion and includes new activities introduced in recent patches and seasonal events.

Compatibility:

The mod requires Seasons and at least one supported pack to unlock the added activities. You don’t need all the packs listed, as activities only appear if you own the corresponding content.

This mod works with the October 31, 202,4 update and remains compatible with the current patch of the game. As it modifies the Spooky Spirit tradition, it may conflict with other mods that directly alter the same tradition entry, but it works smoothly with holiday overhauls that adjust other traditions.

More Time for New Year’s Resolutions

Download: More Time for New Year’s Resolutions

More Time for New Year’s Resolutions extends the duration Sims have to complete their New Year’s resolution goals. The mod is designed to make the tradition more achievable and less rushed.

Instead of expiring within a short window, resolutions can now last two, three, or four full in-game weeks, depending on the version you choose. This creates a more realistic pace and gives Sims enough time to make their progress without constant micromanagement.

Features include:

• Three duration options: 14, 21, or 28 days for New Year’s resolution completion.
• Full control over how long resolutions last.
• Extended timeframes that reduce failed resolutions and improve long-term seasonal goals.
• Works automatically with pre-made EA resolutions, requiring no additional setup.

Compatibility:

The mod requires the Seasons expansion, as it modifies the built-in New Year’s resolution system. It doesn’t affect custom resolutions added by other mods and functions independently of holiday overhaul mods.

The mod remains compatible with the September 18, 2024, patch and only needs to be enabled once in your Mods folder. You can only install one file at a time.

FAQ: Sims 4 Holiday Mods

Do Sims 4 holiday mods require the Seasons expansion pack?

Most holiday mods rely on the calendar and seasonal systems introduced in Seasons, so the majority require that expansion to work correctly. However, there are a few social-interaction and cosmetic mods that are compatible with the Base Game. Always check each creator’s requirements before installing.

Why are some holiday mods not showing up in my game?

If the mod affects the calendar, it may only work in new save files. Clear your localthumbcache.package file, ensure script mods are enabled, and confirm the mod is not conflicting with another holiday overhaul.

Can I use multiple holiday overhaul mods at the same time?

It depends. Calendar-overhaul mods generally conflict with one another, since only one mod can control premade holidays at a time. Smaller add-ons, such as tradition overhauls, social interactions, or snow replacements, usually work together without issues.

Are these mods safe to use?

Holiday and seasonal mods are safe when downloaded from trusted creators. Keep them updated, and always remove older versions before installing new updates. Also, avoid mixing outdated files with current patches.

Do holiday mods affect gameplay or only the calendar?

It depends on the mod. Some add new interactions, improved traditions, and seasonal activities, while others strictly modify the calendar. Read each mod’s description to understand what systems are changed.

Can I customize the holidays added by these mods?

Yes. Most mods allow you to edit holidays, add traditions, or move dates directly through the in-game calendar. Calendar edits don’t affect mod stability.

What should I do if holiday moodlets or traditions behave strangely?

Reset the affected Sim, repair your game, and clear the cache. If you use multiple tuning mods, check for conflicts, especially with mods that alter holidays, traditions, or event autonomy.

Conclusion

That’s it from us, Simmers. These Sims 4 holiday mods offer an easy way to enhance seasonal gameplay, enrich family gatherings, and make winter worlds feel more immersive.

Take your time exploring the options, check the requirements carefully, and mix the mods that best match your preferred style of festive gameplay. Once everything is set up, your Sims can enjoy a December filled with celebrations, winter fun, and memorable seasonal moments.
