Lughnasadh, Lughnasa or Lúnasa is a Gaelic festival marking the beginning of the harvest season. Historically, it was widely observed throughout Ireland, Scotland, and the Isle of Man. Traditionally, it is held on 1 August, or about halfway between the summer solstice and autumn equinox. In recent centuries, some celebrations have shifted to Sundays near this date. Lughnasadh is one of the four Gaelic seasonal festivals, along with Samhain, Imbolc, and Beltane. It corresponds to the Welsh Gŵyl Awst and the English Lammas.
