Holiday

Holidays are a feature in The Sims 4: Seasons. They are worldwide, yearly events, that each come with it's own set of traditions, which define the way the Sims celebrate the holiday. There are multiple pre-made holidays and players are able to create their own. To see when a holiday takes place, players can check the calendar.

Surprise holidays will occasionally pop up in Sims' calendars a few days before they occur, such as "Talk Like a Pirate Day".

Decoration Theme
When it comes to the decoration of the neighboring houses the player can choose from seven decoration themes: The neighboring houses will each time apply random decoration from that theme. The theme is also applied to the player's house, when they choose to decorate using The Attic Stack Decoration Box, but this can be customized via the same object.
