Beltane is a traditional Gaelic festival celebrating the height of spring and the coming of summer, associated with fertility, vitality, and abundance. It is commonly marked with bonfires, dancing, and rituals honoring growth, sexuality, and the flourishing of the natural world. While often celebrated on May 1 (or the eve of April 30), the exact timing is debated, with some observing it as a cross-quarter day or at the full moon nearest the start of May.
