International Museum Day

International Museum Day is an event in held from May 18 to May 31, based on the real-world. During this event, the bug, fish, fossil, and art galleries of the museum 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. The stamp rally can be repeated for the duration of the event, and Blathers will reward the player the prizes again.

International Museum Day was introduced in the 1.2.0 April Free Update, and the stamp stations in the art exhibit were added in the 1.10.0 Free Update.
