Púca night refers to the night of Samhain (October 31) and Púca’s Day (November 1st) in Irish folklore, when the púca is believed to roam the countryside. Farmers traditionally left a small portion of their unharvested crops—known as the "púca's share"—at the edge of the field to appease the spirit and protect the rest of the harvest. After November 1, any wild blackberries or fruit left on the hedgerows were said to be cursed or spoiled by the púca's touch. The folklore is celebrated today during Ireland's annual Púca Festival, an immersive Samhain event featuring fire processions, music, and storytelling in Trim and Athboy.
