On any given day in Animal Crossing New Horizons, you can encounter either Good luck or Bad luck. Each of these offer variations of the luck you receive, including Good or Bad luck with Money, Friendship, Belongings and Health, and for the most part are encountered at random.
However even on days with Bad Luck, it’s possible to use Katrina’s Purification Services to remove all negative effects. Plus there’s rare bonus items available for those who ask for Katrina’s help.
