Spring
Water on the sunny days. Spring 3 rains, in year 1. Parsnip seeds or, on Meadowlands, hay and chickens are the day-1 supplies. On Spring 13, the Egg Festival sells Strawberry Seeds at 100g. Planting on or before Spring 16 is what leaves two harvests before summer.
Spring 15-17 is the Desert Festival if the bus is already repaired. Spring 24 is the Flower Dance. A partner needs four hearts, so a first-year dance is a friendship project, not a default. On the night of the 28th, spring-only crops die.
Year 1 spring weather is fixed for the first five days: sun, sun, rain, sun, sun.
Summer
Green rain happens once, on one of Summer 5, 6, 7, 14, 15, 16, 18, or 23. In year 1 you cannot give gifts that day. Leah is one of the three villagers still outside. Summer 11 is the Luau. Bring an edible item that is not a cooked dish if you want a say in the soup. Normal quality does not get the best response.
Summer 13 and 26 are storms. Summer 20-21 is the Trout Derby, and the day still runs, so the farm still needs water and the animals still need food. Summer 28 is the Moonlight Jellies, on the beach from 10pm. Summer crops that are not also fall crops die that night.
Fall and winter
Fall 16 is the Fair. Nine items, spread across the scored categories, is the shape of a strong grange. The Stardrop at that shop is 2,000 star tokens, once. Fall 27 is Spirit's Eve from 10pm. Odd years hide a Golden Pumpkin. Even years hide a Prize Ticket. Fall crops die when winter starts. Winter is not a normal planting season. Winter Seeds and Powdermelon still need water in the snow.
Winter 8 is the Festival of Ice: five fish wins. Winter 12-13 is SquidFest. Winter 15-17 is the Night Market, and the submarine is 1,000g. Lewis writes on Winter 18 with the name for the Winter Star on the 25th. The gift you give that day is worth five times the usual friendship. Spring 1 starts the next year, with more debris than a normal season change.
