Countdown: Tom Nook and Isabelle host a New Year's Eve party in the plaza from 11 PM. Buy a New Year's hat and party poppers, wave a light stick and watch fireworks greet the new year at midnight.
New Year's Day: The first day of the year. Your villagers greet you with New Year wishes, and the Nook Shopping seasonal tab keeps its New Year goods until 5 January.
Lunar New Year: Lunar New Year follows the lunar calendar, so its date shifts every year. Around the big day, check the Nook Shopping seasonal tab for a lucky red envelope and a festive decoration.
Bunny Day: In the week before Bunny Day, eggs turn up everywhere: dig them up, fish them out, shake and chop trees, hit rocks and pop balloons. Egg balloons, bottles and villagers supply the DIYs.
Bunny Day: On Bunny Day itself, look for Zipper. He is the source of the Bunny Day basket and of special recipes such as the Bunny Day arch, Wobbling Zipper toy and Bunny Day wand.
May Day: Dodo Airlines flies you to a maze island for the May Day Tour. Work your way through to reach Rover, who rewards you with keepsakes such as his briefcase.
International Museum Day: Blathers sets up a stamp rally across the museum. Collect every stamp in the fish, bug, fossil and art wings, and he rewards each completed wing with its own plaque.
Wedding Season: Reese and Cyrus celebrate their anniversary on Harv's island. Set up photo shoots for them to earn heart crystals, which Cyrus trades for wedding furniture and outfits.
Fireworks Show: Fireworks light up the sky from 7 PM on the first Sunday in August. Isabelle hands out a bopper in the plaza and Redd runs a raffle packed with sparklers, balloons and treats.
Fireworks Show: Fireworks night returns for the second Sunday in August. Ask Isabelle to put your custom designs into the show, and try Redd's raffle for boba tea and cotton candy.
Fireworks Show: The third August fireworks night. Enjoy the show from the plaza, collect your bopper from Isabelle and keep playing Redd's raffle for summery prizes like frozen treats.
Fireworks Show: Fireworks fill the sky again on the fourth Sunday in August. It is another chance to complete your collection of Redd's raffle prizes and show off your custom designs.
Fireworks Show: A bonus fireworks night when August has a fifth Sunday. Catch the show, pick up anything you still need from Redd's raffle and enjoy the last summer sparkle.
Halloween: October builds up to Halloween. Villagers and balloons share spooky DIYs made with pumpkins, Nook's Cranny stocks spooky furniture and candy, and Able Sisters sells costumes.
Halloween: Jack haunts the plaza on Halloween night while costumed villagers go trick-or-treating. Hand out candy to earn spooky wallpaper, rugs, lollipops and DIYs, plus Jack's own outfit.
Turkey Day: Franklin cooks a feast in the plaza from 9 AM. Bring him the ingredients he asks for to earn Turkey Day furniture, recipe packs and a cornucopia.
Turkey Day: Missed some prizes? From the day after Turkey Day until November ends, Nook's Cranny sells the Turkey Day furniture along with both of Franklin's recipe packs.
Nook Friday: Nook Friday, added in the 2.0 update, starts the day after Turkey Day and lasts until the end of November, in a playful nod to Black Friday.
Toy Day: Toy Day shopping starts early. Nook's Cranny stocks toys like the dollhouse, tin robot and RC helicopter, and Able Sisters sells festive outfits such as the holiday sweater.
Toy Day: The final run-up to Toy Day. Able Sisters adds Santa and reindeer costumes, and villagers start sharing festive DIYs made from the ornaments you shake from cedar trees.
Toy Day: Jingle visits with a magic bag and needs help giving each villager the present they wished for. Lend a hand to earn Toy Day stockings, the Toy Day sleigh and festive DIYs.
Toy Day: The morning after Toy Day, check the Toy Day stockings you placed for a thank-you from Jingle: his photo. Able Sisters keeps its Santa outfits on sale for one more day.
Festivale: Festivale preparations begin. Nook's Cranny sells bright Festivale furniture and the Viva Festivale Reaction Set, and Able Sisters stocks Festivale costumes.
Festivale: Pavé dances in the plaza while coloured feathers float around the island. Catch them with your net and trade them to Pavé for Festivale furniture and the Festivale float.
Valentine's Day: Valentine's Day falls on 14 February. In the run-up, the Nook Shopping seasonal tab sells a chocolate heart and a heart-shaped bouquet, ideal gifts for your favourite neighbours.
