Seasonal Events

Overview

inZOI features seasonal events tied to both real-world holidays and in-game calendar celebrations. These events add themed activities, exclusive items, decorations, and special interactions. Since the game's Early Access launch on March 28, 2025, KRAFTON has delivered three major real-world seasonal events. The March 2026 update (v0.7.0) then introduced a permanent in-game seasonal holiday system with four recurring festivals tied to the new calendar.

Real-World Seasonal Events

These are limited-time events tied to real-world holidays, delivered through game updates with exclusive content and decorations.

Halloween 2025

The Halloween event launched as part of the v0.4.0 update on October 30, 2025. It was the first seasonal event in inZOI's history and transformed cities with autumn-themed activities spanning both daytime and nighttime gameplay.

Pumpkin Farming and Jack-o'-Lanterns

A new pumpkin crop was added that players could grow on farm plots or purchase from the Farming Supply Store and Pocket Market. Once harvested, pumpkins could be carved into jack-o'-lanterns at a crafting table. Carved pumpkins could be worn as hat items or placed as home decorations.

Trick-or-Treating

The trick-or-treat system centered around the Halloween Candy Basket. By placing this basket on their property, players attracted child Zois who visited every night to ask for candy. The interaction worked as a passive event: children appeared automatically at dusk and lined up at the basket.

Ghost Fish

Five luminescent ghost fish species were added that only appear between 6 PM and 6 AM. These spectral fish can be caught through the regular fishing system and displayed in aquariums. Ghost Fish glow in dark environments, making them especially appealing as decorations.

Additional Halloween Content

• 38 Halloween-themed cosmetic unlockables (costumes, accessories).

• 58 Halloween building items and decorations.

• Ghost Play: Play as a ghost for three in-game days after death.

• Funeral properties: Funeral Home, Columbarium, Cemetery.

Holiday Festival (December 2025 through January 2026)

The Holiday Festival launched with the v0.5.0 update on December 23, 2025, and ran through January 31, 2026. Christmas-themed booths appeared in each city's main park:

Festival Activities

• Choir performances from 12:15 PM to 10:00 PM daily at each park.

• Themed crafting stations and activity booths.

• Five gift boxes delivered to player homes, containing 19 build items plus special gifts on designated nights.

• Over 50 Holiday Festival build items unlockable through event participation.

• 22 total holiday-themed construction pieces available as rewards.

Holiday Items

The v0.5.0 update included 62 new winter-themed outfits with new hairstyles and accessories, 7 unlockable Holiday Festival costume pieces, and 173 new building objects including festive decorations and winter furniture.

Lunar New Year 2026

The Lunar New Year event arrived with the v0.6.0 update on February 12, 2026, celebrating the Year of the Horse with traditional-themed content across character creation and building.

Character Items

19 new Lunar New Year character items were added:

• 2 new hairstyles with traditional styling.

• 9 outfit sets inspired by traditional attire.

• 4 shoe types matching the Lunar New Year theme.

• 4 hats including traditional headwear.

Equipping Lunar New Year items unlocks exclusive social interactions that are not available with regular clothing. This adds extra flavor to social gameplay during the celebration period.

Build Mode Assets

55 new Lunar New Year-themed Build Mode assets were added, including traditional stairs, doors, roofs, furniture, and lighting. These allow players to fully decorate homes and neighborhoods with a traditional Lunar New Year aesthetic.

Horse Mask and Special Content

To celebrate the Year of the Horse, KRAFTON released a Horse Mask accessory with exclusive interactions through a giveaway hosted via the "Brainstorm with Kjun" event on the official inZOI Discord server. The Ullim Temple area received a renovation including an Ullim Cafe update and a new Hanok (traditional Korean architecture) property.

In-Game Seasonal Holidays (March 2026)

The v0.7.0 update (March 26, 2026) introduced a permanent system of in-game seasonal holidays tied to the new 28-day calendar. Unlike the real-world seasonal events above (which are delivered through specific game updates), these four holidays are built into the calendar and recur automatically as in-game time progresses. Each season has its own dedicated holiday festival that provides unique activities and celebrations.

How Seasonal Holidays Work

Seasonal holidays appear automatically on the in-game calendar at fixed points within each season. When a holiday arrives, festivals are held across the game's cities. Players can set different holidays to recur on specific dates, allowing these celebrations to disappear and reappear as the save file progresses through time. This system ensures that long-term gameplay feels dynamic, with recurring celebrations marking the passage of in-game seasons.

Spring Festival

The Spring Festival is a new addition as of v0.7.0 and marks the beginning of each year cycle in the in-game calendar. It is the first entirely new seasonal celebration created specifically for the calendar holiday system. Spring Festival activities provide seasonal festivities during the spring season, giving players a reason to celebrate after the winter months.

Halloween Festival (In-Game)

The in-game Halloween Festival runs during the fall season as a recurring calendar holiday. This is separate from the real-world Halloween 2025 event (v0.4.0), though it builds on much of the same content. The pumpkin farming, trick-or-treating, ghost fish, and Halloween decorations from the original event remain available as permanent content that activates during the fall season.

Winter and Year-End Festivals

The winter season features two celebrations: the Winter Festival and the Year-End Festival. These recurring holidays provide winter-themed festivities at the end of each in-game year cycle. Like the other calendar holidays, they appear automatically and can be configured to recur on specific dates within the season.

Birthday Celebrations

The v0.7.0 update also enhanced birthday parties as part of the seasonal content system. Zois can now throw birthday parties that include gift-giving, blowing out candles on a cake, and smashing a pinata. The pinata is an interactive object that can be broken at parties to release candy. Zois advance to their next life stage either by blowing out candles during a birthday party social event or by spending their birthday alone without a party.
