The Festive Season is an event that occurs in New Horizons. It lasts from December 15th to January 6th, regardless of hemisphere, and serves as a lead-up to Toy Day.
Ornaments
During Festive Season, shaking pine trees will sometimes result in an ornament dropping. There are three types of ornaments: Red, Blue (both with a 7.5% drop chance), and Gold (with a 5% drop chance). These ornaments can be used in special seasonal DIY Recipes.
