Black Spire Day was a festive occasion observed within the Black Spire Outpost settlement, situated on the planet of Batuu. This holiday marked the anniversary of the outpost's establishment. The inhabitants would adorn the outpost with vibrant streamers and coverings, enjoying festivities that included processions and banquets. Sometimes, the celebrations would culminate in a fireworks presentation.
The concept of Black Spire Day was conceived specifically for Star Wars: Galaxy's Edge, which debuted for visitors at Disneyland Park on May 31, 2019. This is the fictional name given to the celebrations that occur within Disney parks on "Star Wars Day" (May the Fourth).
