Fields of Mistria Seasons and Festivals Guide: All 4 (2026)

Fields of Mistria seasons and festivals run on a stricter calendar than the tutorial lets on. Four seasons, 28 days each, and currently four real festivals where the whole town shows up. Not six, not a dozen; four. The wiki has more festivals datamined into the game's files than are actually playable right now, which is the kind of detail a "complete" seasonal guide will happily gloss over if nobody bothers to check the source.

Updated 2026-10-05: Steam's latest official news is Patch Notes v1.0.6, which adds memory-leak, crash, and OBS capture fixes without adding another playable festival; our Fields of Mistria review tracks the broader patch trail.

TL;DR: Fields of Mistria runs on four seasons, Spring, Summer, Fall, and Winter, each lasting exactly 28 days for a 112-day year. Only four festivals are currently playable: Spring Festival (Spring 17), Shooting Star Festival (Summer 28), Harvest Festival (Fall 10), and Animal Festival (Winter 10). Six more festivals, including a Halloween Festival and a New Year's Eve event, are sitting in the game's data unreleased. Crops, forageables, fish, and bugs all change with the season, and NPCs swap outfits too.

What are Fields of Mistria's seasons and festivals? (quick answer)

Fields of Mistria has four seasons, Spring, Summer, Fall, and Winter, each lasting 28 days. Each season carries one live festival where villagers gather for games, prizes, and special dialogue: Spring Festival, Shooting Star Festival, Harvest Festival, and Animal Festival. Six additional festivals are confirmed in the game's data but not yet playable.

Key Takeaways

• Four seasons, 28 days each. A full year is 112 days, unchanged by the 1.0 update.
• Four festivals are actually live: Spring Festival (Spring 17), Shooting Star Festival (Summer 28), Harvest Festival (Fall 10), Animal Festival (Winter 10).
• Six more festivals exist in the game's data but haven't shipped: Cooking Contest, Beach Day, Crop Festival, Halloween Festival, Gift Festival, and New Year's Eve.
• The season determines which crops, forageables, fish, and bugs you can find, and unharvested seasonal crops wither when the season ends.
• Steam's own store page confirms villager outfits change by season, not just the scenery.
• 1.0's patch notes fixed bugs on two of the live festivals (Harvest and Shooting Star) but didn't add a new one.

Overview: How the Fields of Mistria Calendar Works

Each of the four seasons runs 28 days, which the game's own wiki lists plainly: four weeks per season, four seasons per year, 112 days total before the calendar loops back to Spring 1. That structure hasn't shifted since 1.0 launched on August 5, 2026. NPC Studio's own patch notes for the update mention seasonal music additions (a new winter song, four existing seasonal tracks getting extended versions later in the game) but nothing about the season length itself, and neither does the wiki's changelog for the update.

What actually changes season to season goes beyond a color palette swap. The wiki is specific about this: "The Season determines the Crops that can be grown, Forageables that can be found, as well as the Bugs and Fish that can be caught." Plant something out of season and it won't grow at all, and a crop that's already in the ground withers once its season ends unless it's one of the few that spans two seasons. Fruit trees follow the same rule; they simply stop producing once their window closes. Some of what changes is cosmetic only, the wiki calls out "the changing colors of outdoor scenery" specifically, but Steam's own About the Game section adds one more layer that a lot of farm sims skip: "Enjoy the changing seasons with new quests, festivals, and even villager outfits!" That's a direct quote from the store page, not a paraphrase. It means the villagers you talk to every day are dressed differently depending on which quarter of the year it is, which is a small detail, but it's the kind of thing a spiritual successor to a 90s farm sim usually skips.

Summer's crop lineup includes corn, watermelon, and tomatoes, all of which stop growing the moment the calendar flips to Fall.

Step-by-Step: The Festival Calendar, Season by Season

This is the part most seasonal guides get wrong by either listing festivals that don't exist yet or skipping the ones that do. Here's what's actually playable, season by season, cross-checked against the game's own wiki and, for two of the four, against NPC Studio's own 1.0 patch notes.

Use this four-stop calendar checklist before reading the detailed sections:

1. Spring Festival on Spring 17. Collect Breath of Spring flowers before Celine gathers them for the town celebration.
2. Shooting Star Festival on Summer 28. Finish the required story quest and reach 4 hearts with the Romanceable NPC you want to invite.
3. Harvest Festival on Fall 10. Gather Queen Berries from Fall 7 onward so you can enter the judging and feast.
4. Animal Festival on Winter 10. Register one large animal and one small animal for the two judging categories.

Spring: Spring Festival on Spring 17

The Spring Festival lands on day 17 and it's the one festival in this guide that got directly screenshotted for this article rather than described secondhand (see the hero image above). It plays out as a town-wide gathering: villagers cluster around a decorated stage under a cherry blossom tree while a host, Josephine in the version pictured, announces competition results in front of everyone. In the scene captured for this guide, she's reading off "the three people who turned in the most Breath of Spring flowers," which lines up with the wiki's general description of festivals as "holiday-specific games & prizes, items for purchase and special dialogue" rather than being some kind of passive cutscene.

Summer: Shooting Star Festival on Summer 28

Summer's festival sits at the very end of the season, day 28. The wiki notes that experiencing the date portion of the event requires finishing a specific story quest first, and any Romanceable NPC you want to bring along needs a Heart Level of at least 4 before they'll accept. NPC Studio's own 1.0.1 and later patch notes confirm this festival is actively maintained, not abandoned: one fix specifically stopped "Shooting Star Festival-related dialogue" from firing past midnight on Summer 27, a day-boundary bug that would've broken the event's setup dialogue for anyone playing late into the night before the festival itself.

Fall: Harvest Festival on Fall 10

The Harvest Festival runs on Fall 10, but entries for its centerpiece open earlier, Fall 7th, per the wiki. The event centers on a Queen Berry gathering competition: turn in your berries before judging, then stick around for a feast and the option to ask an NPC to dance once winners are announced. This is also the festival 1.0 touched directly. NPC Studio's patch notes list a fix for a scoring bug where "players can no longer earn second place in the Harvest Festival despite turning in a winning amount of Queen berries," which tells you the competition's placement logic is more involved than a simple highest-number-wins check, and that it was actually broken for some players before the fix landed.

Fall's harvest crops (pumpkins, carrots, apples) and the animal pen both feed into the Harvest Festival's competition and feast.

Winter: Animal Festival on Winter 10

The Animal Festival, added to the game in update v0.13.0 during Early Access, runs on Winter 10. You enter one large animal and one small animal into judging, and prizes come as animal cosmetics and barn decor rather than farming materials or cash. It's the smallest of the four festivals in terms of documented scope, no dating mechanic, no multi-day entry window like the Harvest Festival's Queen Berry competition, just a single judged category per animal size.

Mining stays available through Winter even when the surface farm has little left to tend, one reason Winter runs don't feel as empty as the season's crop list alone would suggest.

Two of these four festivals, Spring and Summer's, tie directly into relationships: the Spring Festival's flower competition and the Shooting Star Festival's dating invitation both hinge on where you stand with a specific NPC out of the game's 12 marriage candidates.

What's Coming: 6 Unreleased Festivals Already in the Game's Data

Here's the part that separates a checked calendar from a guessed one. The game's own wiki flags six additional festivals that are named, dated, and sitting in Fields of Mistria's data files but not currently playable: Cooking Contest (Spring 24), Beach Day (Summer 5), Crop Festival (Summer 18), Halloween Festival (Fall 28), Gift Festival (Winter 24), and New Year's Eve (Winter 28). The wiki is upfront that this information came from datamining, not from an official NPC Studio announcement, and it carries an explicit warning that none of it is implemented yet.

Worth being honest about what that means: a datamined event existing in the files is not a promise. Games sit on unused content for years sometimes, or ship it in a form different from what got mined out early. NPC Studio's own 1.0 patch notes make no mention of adding any of these six, only bug fixes to the two seasonal festivals that were already live (Harvest and Shooting Star). If you're the type of player who plans a save around a Halloween costume that doesn't exist yet, that costume isn't coming with any confirmed date attached. Treat this list as "known to be planned in some form," not "coming next patch."

Tips for Festival Season

Check the Queen Berry window before Fall 10 hits. The Harvest Festival's main competition opens for entries on Fall 7th, three full days before the festival itself. If you show up on the 10th with zero berries banked, you've missed the entire point of the event.

Save your best animals for Winter 10, not your newest ones. The Animal Festival judges one large and one small animal at a time. A freshly purchased animal with low stats or low friendship will lose to whatever you've been raising all season, so plan which pair you're entering before the day arrives, not on the morning of.

Raise a Romanceable NPC's Heart Level to 4 well before Summer 28. The Shooting Star Festival's dating invitation locks behind both a story quest and that heart threshold. Waiting until the week of the festival to start building a relationship from scratch won't get you there in time.

Don't plant a crop you can't harvest before its season ends. Because seasonal crops wither at the season boundary unless they carry over, timing your last planting against the 28-day countdown matters more than it does in farm sims where crops are season-agnostic.

Watch for NPC outfit changes as a season-check, not just the calendar UI. Steam's own store description calls out villager outfits changing by season specifically. If you're ever unsure what season it currently is mid-conversation, what an NPC is wearing is a second confirmation beyond the corner-of-screen calendar widget.

Frequently Asked Questions

How many seasons does Fields of Mistria have, and how long is each one? Four: Spring, Summer, Fall, and Winter. Each one runs 28 days (four weeks), so a full in-game year is 112 days. This hasn't changed with the 1.0 update.

How many festivals are currently in Fields of Mistria? Four are actually playable: Spring Festival (Spring 17), Shooting Star Festival (Summer 28), Harvest Festival (Fall 10), and Animal Festival (Winter 10). Six more exist in the game's data but aren't live yet.

What happens at the Harvest Festival? You can enter the Queen Berry gathering competition, which opens for entries starting Fall 7th, then watch the judging, eat a feast with the town, and ask an NPC to dance once winners are announced.

What happens at the Animal Festival? Enter one large animal and one small animal into judging for a chance at animal cosmetics and barn decor. It runs on Winter 10 and was added to the game in update v0.13.0.

Are there more Fields of Mistria festivals coming? Six are datamined but not yet playable: Cooking Contest (Spring 24), Beach Day (Summer 5), Crop Festival (Summer 18), Halloween Festival (Fall 28), Gift Festival (Winter 24), and New Year's Eve (Winter 28). No release date is confirmed for any of them.

Does the season change which crops and fish I can find? Yes. Crops, forageables, fish, and bugs are all season-locked, and seasonal crops wither at the end of their season unless they also grow in the next one. Fruit trees stop producing when their season ends too.

What do I need to bring a date to the Shooting Star Festival? You need to finish the story quest that unlocks the date option, and the NPC you want to invite needs a Heart Level of at least 4. The festival itself falls on Summer 28.
