International Museum Day

International Museum Day is an event in held from May 18th through May 31st, based on the real-world. During this event, the bug, fish, and fossil galleries will each contain three stamp stations which may change location each day. Interacting with the stations will let the player stamp their card. After obtaining all three stamps from a gallery, the player can talk to Blathers, who will congratulate them and give them a completion stamp and a prize — a plaque based on the gallery associated with the completed card.
