The household calendar and holidays were added to the Sims 4 in the Seasons expansion pack. Later on, the calendar was added to the base game (click here to learn how the calendar works). Holidays have remained exclusive to the Sims 4 and they continue to be one of my most used features from that pack! Holidays can add both realism or mania into your game depending on how you customise them. In this post, I will explain how to make, edit, and delete holidays in the Sims 4. Additionally, I include everything you need to know about holiday traditions in the game. 

How to Make, Edit, and Delete Holidays in the Sims 4 

It’s really easy to add new holidays into your game and edit the premade ones. Here’s how to do it: 

Create Custom Holidays 

Step #1 – Open The Calendar

Open the calendar, select which day to put the holiday on, and click add a holiday on the left hand side of the calendar display.

Step #2 – Holiday Name

Type in a name for your holiday in the bar at the top of the pop-up.

Step #3 – Personalise the Holiday 

Customise each of the following features of your holiday: 

  • Holiday Icon (Top left)
    • There are 27 unique icons to choose from. If you want more options, then some talented simmers out there have created mods that add more into your game. 
  • Decoration Theme (Top Right)
    • Decorations can be put up using The Attic Stack Decoration Box object (can be bought from build/buy mode) and they will hang from the fences and roof trims of your sim’s house. 
  • Day Off Work/School (Top Right below Decoration Theme)
    • This option determines whether your sims go to work or school on the day of the holiday or not. If ticked, then they will not attend. 
  • Select Traditions (Bottom)
    • Up to five traditions can be chosen, but none are required in order to create a holiday. All of the traditions available are explained later on in this post. 

Step #4 – Save the Holiday to your game

Select the tick mark in the bottom right hand corner to add the holiday to your sim’s calendar. Holidays save to the calendars of all households in that save file, so if you play with a different household in the same game save, then the holidays that you have created will appear in their calendar’s as well! 

Holidays will automatically appear each year (every time the season returns) unless deleted. 

Edit or Delete Holidays 

Open calendar, select the day with the holiday that you want to edit. On the left hand side of the screen next to the holiday name are two options. One is to edit the holiday, which will open up the same pop-up as when you’re creating a holiday so you can edit everything about it. The other option is to delete the holiday from your sim’s calendar. The holiday will be deleted from all calendars in that save file. 

Premade Holidays 

When you load into a new game save file, the following four holidays with these traditions will already be scheduled in the calendar: 

Love Day – Romantic Spirit, Give Flowers, Go on a Date (Spring) 

Harvestfest – Decorate, Holiday Gnomes, Grand Meal, Thankful Spirit (Autumn) 

Winterfest – Decorate, Festive Spirit, Open Presents, Grand Meal, Father Winter (Winter) 

New Year’s Eve – Decorate, Party Spirit, Make Resolutions, Countdown to Midnight (Winter)

Surprise Holidays 

There will also be surprise holidays that are not shown in the calendar. They will appear in the calendar randomly and only a few days before they occur. These holidays cannot be altered by the player and some have unique traditions. The surprise holidays are: 

Neighbourhood Brawl – Fighting

New Skill Day – Skill Improvement

Night on the Town – Free Food and Drinks

Prank Day – Mischief Spirit

Rebate Day – Shopping Rebate

Talk Like a Pirate Day – Talk Like a Pirate

The Lottery – Play the Lottery 

TV Season Premiere – Watch TV Premiere 

How Seasons Affect Holidays 

Season lengths can be adjusted in the Sims 4 and this affects the days on which holidays occur.

  • 7 Days
  • 14 Days
  • 28 Days

Holidays will remain in the same season that you created them in if you change the season length. This means that if you create a halloween holiday in the middle weekend of the autumn season when your seasons are set to be 14 days long and then you change season length to 7 days, halloween will remain in the autumn season but might move to the middle of the week to reflect being in the middle of the season. It is not exact and is a bit unpredictable where holidays will move to if you change the season length, so I recommend sticking to one season length for the game save that you don’t change.

All Holiday Traditions in the Sims 4 Seasons

Your sims traits and age can affect whether they ignore a tradition or love a tradition. If ignored, a tradition is treated as though it doesn’t exist for that sim, so it does not need to be completed to have a successful holiday.
