Seasons Expanded
by wexxamsims, for The Sims 3

AI Disclosure
This mod was made with AI. I decided what goes in it and how everything should work and look, and I tested it in game with help from players, but the scripts were written by Claude (Anthropic's AI). Claude also did most of the translations, and upscaled some icons and images. Anything that came from other people is credited at the bottom.
Seasons was one of the biggest EP releases for TS3 and one of the most popular themes demanded by the community. When TS3 Seasons released I felt a little disappointed, because after a few Sim years of going to the festival lot every holiday, you're left with the question - is that it...?

Well, not anymore! Seasons Expanded adds new things to do in every season, makes the world feel more alive, and gives every household its own calendar to keep track of it all.

This is the final version! I will continue to optomise and make any bug fixes when needed however this is the last big feature I had planned for this mod!

Update v.7.1b
  • Fixed an issue with the moons not showing correctly on the calendar. All moon settings should now work correctly and show on the calendar.

Update v.7.1

The Household Calendar
  • Every day ahead now shows its moon phase. Some days used to stay blank until you'd played through a full moon cycle. It follows your game's moon settings, and a day you haven't reached yet can be one phase off until that night comes.
  • If you lock the moon to one phase in the game's options, that phase now shows on every day instead of only the days with a forecast.
  • Added support for Tiny UI Fix, so the calendar scales up with the rest of your UI.

For Modders
  • Other mods can now add their own events to the calendar. It only takes one small class in your mod, you don't need to reference Seasons Expanded, and your mod still works fine for players who don't have it. Message me for the guide!

Credit and Thanks
  • Thanks to Iceflower for the idea of letting other mods use the calendar.

The Household Calendar
A household calendar like the one in The Sims 4. Open it with the new button next to the town and Sim buttons on the Sim panel.

The Calendar Itself
  • Four weeks on a page, with Back and Next to look further ahead. Every day is a box shaded by season, with that season's icon in the background.
  • Today is outlined and glowing, past days fade out, and there's a Today button to jump back.
  • Holidays get their own background, and their pictures glow in the season's color.
  • Every day shows its moon phase, and the days the game has a forecast for show the weather too.
  • The big picture on a day goes by what matters most: holidays first, then birthdays, anniversaries, births, and graduations, then anything you've planned, then the first event of the day.
  • Click a day to see it on the left: the week number, the weather, who has work or school, and everything going on that day.
  • Filter it by Sim and by kind of event: Work & School, Birthdays & Family, Holidays & Festivals, Parties & Events, Town, Opportunities, Bills, and Gigs.
  • The map music plays while it's open.

What Shows Up
  • Your Sims: birthdays (pets too), work and school hours (custom careers too, as long as they have set hours), after-school activities, prom, graduations, boarding school days with the school's own crest, the parents' free vacation, baby due dates, and wedding and work anniversaries.
  • Holidays and festivals: every holiday, summer break, the Spring Festival egg hunt, the Flower Gnome, Love Day movies, the Leisure Day fireworks show, trick-or-treating, the Spooky night ghosts, the Harvest Food Drive, Agatha's pie visit, the Holiday Decorating Contest and its winner, and Father Winter's visit.
  • Around town: movies, plays, symphonies, and concerts at the theater, games and concerts at the stadium, SimFest, and neighborhood events like the Grill-a-thon and Chess Mastery.
  • From the expansions: Late Night movie screenings and band gigs, Showtime gigs and performer's shows, horse competitions from Pets, college sports games from University Life, and bot competitions, Holo-Adventures, and the DigiBlast Show from Into the Future.
  • Money and mail: bills, investment payouts, weekly pay from active careers, roommate rent, book club deliveries, and lottery drawings.
  • Parties your Sims are invited to (with the host, place, and dress code), and opportunities with set hours or a deadline.

Planning Ahead
Pick a day that hasn't come yet, then:
  • Plan an Event opens the game's own party window. Weddings, birthdays, holiday parties, and funerals for any Sim with a grave or urn are all in there.
  • Plan an Event At... does the same at a community lot.
  • Plan a Date... lets you pick who with, where, and what time. At that hour the game's own date starts.
  • Plan a Trip... (World Adventures) and Go to University... (University Life) use the game's own windows, or NRaas Traveler's if you have it.
  • Book a Resort Stay... (Island Paradise): pick the resort, the stay, who's coming, and what time.
  • You get one event, one date, and one trip, university term, or resort stay per day, and every Cancel button asks first and tells you what you'll get back.
  • At university you can plan events and dates up to the last day of your term. On vacation you can plan dates and resort stays for the days you're still there. In the future it's today only.

Paying
  • You pay once, when you book it. That's the price the game's window shows or the lot's rent, and nothing else gets taken on the day.
  • If your household can't afford it, it doesn't get booked.
  • Cancel it yourself and you get 75% back.
  • If it can't happen on the day you get all of it back, with a pop-up telling you why.
  • Dates are free!

On the Day
  • Planned events are handed to the game 3 hours before they start, same as planning one on the phone.
  • You get a heads up an hour before a trip, term, resort stay, or date, and at the hour you picked your Sims leave on their own. That's the only time the mod moves your Sims, and only for things you booked yourself.
  • On vacation the calendar counts the days of your trip. At university it shows your term and degree credits.

Notes and To-Dos
  • Write notes on any day, up to 500 letters, for one Sim or the whole household, and keep a to-do list too.
  • Tick something off and it gets crossed out. Click it to change or delete it.
  • Notes can repeat on the weekdays you pick.
  • Notes pop up at 8 AM on their day. Notes for a single day stay until the new year, and repeating notes and to-dos stay until you delete them.

Reminders
  • Stuff the game never warns you about gets a reminder pop-up with its own picture: anniversaries, babies on the way, opportunities, games, shows, SimFest, town events, planned dates, and more.
  • They come an hour before something starts, or at 8 AM for all-day things. Hover over one in the Reminders list to see when it pops up, and hover over the Reminders box to see what's off.
  • If three or more come at once they're grouped into one pop-up.
  • Each day has its own round button to turn that day's reminder off, and the Reminders list turns a whole kind on or off. That goes for the game's own pop-ups too, like holidays, birthdays, prom, bills, and gigs.
  • The Into the Future ones (bot competitions, Holo-Adventures, and the DigiBlast Show) start off. Tick them on if you want them.

Households and UI Mods
  • Each household has its own calendar, notes, and reminder settings, and its plans stay with it. If a plan's day comes while you're playing another household, it's called off and paid back in full.
  • The game cancels a household's opportunities when you switch away from it, so they drop off the calendar too.
  • UI mods work with it! Recolors and the Cloud UIs change the calendar's button and words to match.

Summer
  • Summer break: no school for children and teens all summer, and teachers get paid days off. School options are greyed out, the career panel counts down the days, and you get a pop-up when the break starts and the evening before school starts again. Don't want it? There's an optional No Summer Break add-on.
  • Pool parties last longer. Guests arrive in swimwear, don't leave over a little hunger, and get out of the pool to eat and chat. At public pools they fire up the grill too, and NPC pool parties at someone's home actually use the pool.
  • Once every summer, guaranteed, a teen pranks your house one evening. You get a pop-up, and the police only scold you when it's your own teen.
  • Busier pools, beaches, and festival lots, with BBQs, water balloon fights, and kids playing in sprinklers.
  • Leisure Day: water activities, fireworks, and grills get a sun icon in the pie menu.
  • Leisure Day Fireworks Extravaganza: a pop-up at 6 PM, then at 7:30 PM the show goes up on its own at the summer festival and a crowd comes to watch.
  • New "Perform Firework Extravaganza" option on the big sky fireworks (Golden Dragon, Facemelter, Sugar Explosion, and Sky's Ablaze). It lights every one on the lot one after another, plus the ones your Sim carries when you pick it from the inventory. Red Glare and Holiday Cannon keep the game's own options.
  • Festival contests (the hot dog contest in summer, pie eating and apple bobbing in fall): crowds gather to watch, you get a pop-up when sign-ups open while your Sim is there, the winner pop-up shows the food, and there are 4 hours between contests. Pie eating and apple bobbing never run at the same time on one lot, and starving or miserable Sims can enter too.
  • Swim Around is now an option you can pick yourself: up to 2 hours of swimming in pools, the ocean, and ponds. Sims get out of the water on their own if they start to drown.
  • Bars at beaches, parks, and pools open at 10 AM, and Sims at the pool order drinks at the pool bar.
  • Spray tans cost §200.
  • Snow cones cost §5 on community lots and stay free at home. Each flavor shows the price, and the option is greyed out if your Sim can't afford it.
  • New pop-up icons for the fireworks sale, the fireworks show, Leisure Day, and the contests.

Fall
  • Raking takes longer and is less messy, and playing in leaves lasts longer and drains less hygiene.
  • New volunteering during fall at City Hall, the School, the Bookstore, and the Grocery Store (and the Hideout for Evil Sims!). You can also donate Simoleons, food, or produce to City Hall, and donating §50,000 at once makes your Sim a Harvest Hero!
  • Trick-or-treating completely fixed! 3 to 5 groups of kids come to your door, all in complete, correct costumes. Most NPC adults go home on Spooky Day so your Sims can trick-or-treat too, with curfew at 1 AM.
  • Teens and up can Give Trick or Treat to any child or teen on Spooky Day and the day before.
  • Ghosts roam the graveyards and the festival lot on Spooky night and the night before.
  • Haunted house: "Enter With..." takes your household and the clicked Sim's free friends, partners, and relatives through together (up to 7). Everyone who makes it out gets the Survived It Together moodlet.
  • Costume Parties and Feast Parties are rebalanced, and there's a new Give Thanks interaction.
  • Every costume is finished now, so no everyday hats, shoes, or socks show with it. Change Into Costume... works for every age at costume parties, on the Sim or at a dresser, and Sims can compliment each other's costumes.
  • Some NPC homes get more light decorations and pumpkins outside.
  • The day after Spooky Day, Agatha Crumplebottom brings your household a freshly baked pie between 5 and 7 PM. If nobody answers she leaves it on the doorstep.
  • The Spooky radio station plays The Sims 4's songs.
  • New pop-up icons and new wishes.

Winter
  • Holiday Decorating Contest at City Hall: enter from winter's second day, 9 AM to 9 PM, until 2 days before Snowflake Day. Winners are announced at 8 AM the day before Snowflake Day and get §3,000 to §5,000 plus 100 festival tickets.
  • Father Winter comes on Snowflake Day just after midnight, eats any cookies you leave out, and puts presents under your tree (no tree? he leaves a Bunch o' Gifts). He can also pay one surprise visit each winter if your lot has 2 of these 3: a real fireplace, cookies, and a Holiday Tree. While he's there your Sims can ask him for a holiday gift once a day, and seeing him gives them a moodlet (Supernatural Fans love it, Skeptics don't buy it).
  • If you have the Store's Sims Santas or More Holiday Presents sets, Father Winter wears their Santa hat and robe.
  • A new Winter Holiday radio station!
  • The Holiday Tree works now. Sing carols together (up to 8 Sims, and children sing with their own animation), view it, and place presents under it. Around the Sims 3's converted holiday trees work the same way.
  • Gift Giving Parties are rebalanced and use the presents under your tree, or your Bunch o' Gifts if you don't have one.
  • Some NPC homes get more holiday lights, and snowmen once the snow is deep.
  • New pop-up icons and new wishes.

Spring
  • The Flower Gnome (University Life) is the Spring Festival's mascot! Every day of spring from the second, 8 AM to 9 PM, he's at the Spring Festival in his gnome suit with rainbow sparkles. He does mascot routines, looks for eggs, and chats with Sims, especially kids.
  • His "Flower Gnome..." menu: Give Flowers (5 picked wildflowers, once a day per Sim, for 10 festival tickets and a small chance at a Special Egg or a Spring Gnome), ask for a Backflip, the Running Man, or the Mascot Dance, and Spring Cheer. Watching a routine or a Spring Cheer gives the Flower Power moodlet.
  • He can also Cure Sickness once every 3 days (it works with Twinsimming's Sickness & Health too), and with Supernatural he'll share the Secret to Friendship once a spring.
  • Otherwise he's a normal Sim. Your Sims can befriend him, romance him, marry him, and move him in, and then another man takes over as the Flower Gnome.
  • Plants grow about 25% faster, produce sells for 10% more, and plants don't go dormant in spring anymore.
  • More eggs on the festival lot.
  • The town gets out more in spring. NPC kids head to the Spring Festival to play and go after butterflies and other critters, and NPC teens and up go fishing.
  • More couples out and more romantic interactions used autonomously, and even more on Love Day!
  • Love Day: hearts show in the pie menu beside romantic options, eating out, and going to the movies with someone, theaters show movies all day, and NPC kids get a big egg hunt at the Spring Festival.
  • New Spring Cleaning wish and moodlet.
  • Catch a butterfly in spring and your Sim gets the Butterfly Catcher moodlet.
  • Sims play in rain puddles for longer.

All Year
  • Neighborhood events fixed: the Grill-a-thon, Chess Mastery, Community Meet 'n' Greet, and Music Appreciation Day finally have Sims taking part. Anyone already on the lot joins in, and while your Sim is there up to 6 townies will show up.
  • Supernatural Sims get a boost in their own season, with a moodlet that lasts the whole season and its own icon for each kind: vampires, witches, and ghosts in fall, werewolves in winter, fairies and PlantSims in spring, and mermaids in summer.
  • The Change of Taste lifetime reward shows all the pack favorites.
  • Attraction includes favorites and star signs. Babies get a star sign that matches the season they're born in, and twins always share one.
  • Gardeners are back and can be hired like any other service Sim!
  • Festival rewards cost more tickets, the Festival Frequenter reward works, and festival tickets no longer double when you drag them around an inventory.
  • Work uniforms always stick, even for NPCs. Bartenders and paparazzi get no hats and fitting hairstyles, paparazzi wear a matching outfit, pool bar staff wear resort outfits, and baristas wear aprons.
  • Don't want the uniforms? Open the cheat box (Ctrl+Shift+C) and type workuniforms off. It's saved with each save, and workuniforms on turns them back on.
  • Sims in their work clothes are never too hot or too cold, and they keep them on in the cold.
  • Sims in a party dress code stay in it.
  • Young adults no longer keep their old outerwear when they turn into adults.
  • With the Store's Specter Sweets (and Showtime and Supernatural), Sims can Take a Treat from it.
  • Hovering over the season on the Sim portrait shows when the next holiday is.
  • Festival pop-ups get their season's festival icon.
  • Father Winter, Agatha, and the Flower Gnome can't die and never become celebrities.
  • A watchdog keeps the game's clock running if another script would otherwise freeze it.
  • Translated into 20 languages: Chinese (Traditional), Czech, Danish, Dutch, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese (Brazil and Portugal), Russian, Spanish (Spain and Latin America), and Swedish.

Requirements
  • The Sims 3 Seasons.
  • LazyDuchess's Mono Patcher, fully installed: its package and its ASI loader, as its guide explains.
  • The package goes in Mods\Overrides (your Resource.cfg needs the Overrides folder).
  • Install only this one package.

Optional Packs
Anything for a pack you don't have is skipped.
  • World Adventures: trips on the calendar.
  • Generations: teen pranks, prom, graduations, and boarding school.
  • Pets: horse competitions and pet birthdays.
  • Late Night: bar uniforms and hairstyles, band gigs, and movie screenings.
  • Showtime: performer gigs, SimFest, and performer's shows.
  • Supernatural: the supernatural season boosts.
  • University Life: university terms, college sports games, roommate rent, and the Flower Gnome.
  • Island Paradise: pool bars, resort outfits, and resort stays.
  • Into the Future: the DigiBlast Show, bot competitions, and Holo-Adventures.

Works With
  • NRaas Traveler (the calendar uses its trip and university windows), NRaas Register (Father Winter is protected from its clean-up and never gets an NPC job from it), and NRaas Tempest (Seasons Expanded leaves the weather to it).
  • simler90's Gameplay Core Mod.
  • Destrospean's More Favorites.
  • PhoebeJaySims' Social Clubs (club meetings show on the calendar).
  • Twinsimming's Sickness & Health and Sunscreen Mod.
  • icarus_allsorts' Fun in the Sun (its activities get the Leisure Day sun icon too) and Buyable Beach Towels.
  • Fantuanss12's Skill Certificate Fix.
  • UI mods, recolors and full restyles both.

Conflicts
  • Older separate versions of these mods: Better Trick or Treating, Fall, Winter, Spring, or Summer Overhaul, Gardener Service, Work Uniforms, Favourites Attraction, Supernatural Seasons, Festival Ticket Fix, and Festival Reward Prices. Take them out of Mods, they're all inside this package now.
  • Mods that change the same things, for example other trick-or-treat or Spooky Day mods, Santa or Father Winter mods, holiday contest mods, festival reward or ticket mods, work uniform mods, gardener mods, and pool party mods. Only one of two mods can change the same game code, and Seasons Expanded's tuning wins from Mods\Overrides.
  • Children and Teens Around Town: its trick-or-treat change is replaced by Seasons Expanded's own, the rest of it works.

Game Files This Mod Changes
Nearly everything in the package is new and has its own keys, including all of the text tables. These are the only original game resources it replaces, so another mod that replaces one of these will conflict with it:
  • Stereo (XML): adds the Winter Holiday station.
  • The stereo's song list (XML in UI.package, 0333406C:00000000:1FEC29174D016E18): the Spooky station's songs.
  • FestivalTicketRewards (XML): the ticket prices of the festival rewards.
  • Sims3.Gameplay.Objects.Environment.LeafPile (XML): kPlayTimeMinMax and kRakeTime.
  • Puddle tuning (XML, 0333406C:00000000:4465963928B2065F): kTimeToSplash.
  • Egg tuning (XML, 0333406C:00000000:83835E5FDEC0D981): kChanceForSpecialEgg.
  • Interaction tuning (ITUN): LeafPile+Rake and LeafPile+PlayIn (Hygiene), SwimAround and SwimAroundInOcean (DisallowUserDirected off), EatingContestStand+ParticipateInContest (stressExit off), and TrickOrTreatSituation+TrickOrTreat (DisallowUserDirected on).
  • Festival Ticket object (OBJD 319E4F1D:78000000:000000000098B017): its price is set to 0.
  • The certificate model (instance 00000000002B4708): the one from Fantuanss12's Skill Certificate Fix.
  • Pictures: the Spooky music icon in Create a Sim's favorites (cas_favs_music_i_Horror and its small version).
The scripts don't replace any of the game's core files. They use Mono Patcher to replace about 60 game methods, mostly for trick-or-treating, costume parties, curfews, Father Winter, gift parties, holiday pop-ups, and attraction.

Installing
1. Install Mono Patcher first.
2. Close the game. Put wexxamsims_SeasonsExpanded.package in Documents\Electronic Arts\The Sims 3\Mods\Overrides.
3. Take out any older separate versions (see Conflicts).
4. Delete your cache files in Documents\Electronic Arts\The Sims 3 (CASPartCache, compositorCache, scriptCache, simCompositorCache, and socialCache) and start the game.
Updating: close the game, replace the package with the new one, and delete the caches again. Your saves are fine.

Uninstalling
1. In every save you played with it, open the cheat box (Ctrl+Shift+C), type gardenerservice remove, then save. (The gardener service is saved in your game and this takes it out cleanly.)
2. Close the game, delete wexxamsims_SeasonsExpanded.package from Mods\Overrides, and delete your cache files.
Father Winter and any gardeners stay in town as normal Sims. Decorations on NPC homes stay as normal objects, so delete them in Build mode if you like. Removed the gardener service by mistake? Type gardenerservice restore.
