The first mornings
You wake on Spring 1. In year 1, Spring 1, 2, 4, and 5 are sunny, and Spring 3 rains. Outdoor crops drink the rain. Every other spring day they need the can, until a sprinkler exists. The forecast for tomorrow is on the TV. The rules for the 28th are on Seasons.
On a standard map, Lewis's letter includes 15 parsnip seeds. On Meadowlands Farm, that letter is 15 hay instead, and a coop with two chickens is already in the yard. Either way, spring crops that are not also summer crops die when summer starts.
A crop planted on Spring 1 and watered that day spends the night growing. Missing a day of water pauses it. It does not kill it.
Festival days are sunny, so the Egg Festival will not water the field for you.
People and the calendar
Gifts are two a week, and a birthday is worth more. The numbers and the five taste tables are on Friendship and gifts. Abigail, Haley, Sebastian, Leah, and Penny each have a page.
The festival calendar is the other clock. Spring 13 is the Egg Festival, and Pierre's booth there sells strawberry seeds at 100g. A full pass through the dates is First year. New systems from the current line are on Update 1.6.
