Spring
Day 1
The first day is an introduction to the game. You will be brought to town by the Friendly Shipper. You need to speak with six people in town before you can go back to the farm: The Flower Shop Owner, the Livestock Dealer, Nina, Ann, Maria, and Eve. I would still suggest exploring and talking to everyone in town. After you talk to the people in town, you can speak to the Friendly Shipper and he will bring you back home. You immediately go to bed.
Day 2
Day 23 - Flower Festival

The Sprinkler becomes available in the tool shop for 2000g.
