Lughnasadh or Lughnasa (pronounced LOO-nə-sə; Irish: Lúnasa; Scottish Gaelic: Lùnastal; Manx: Luanistyn) is a Gaelic festival marking the beginning of the harvest season that was historically observed throughout Ireland, Scotland and the Isle of Man. Originally it was held on 31 July – 1 August, or approximately halfway between the summer solstice and autumn equinox. However, over time the celebrations shifted to the Sundays nearest this date. Lughnasadh is one of the four Gaelic seasonal festivals; along with Samhain, Imbolc and Beltane. It corresponds to other European harvest festivals, such as the Welsh Calan Awst and the English Lammas.Lughnasadh is mentioned in some of the earliest Irish literature and is believed to have pagan origins. The festival itself is named after the god Lugh. It involved great gatherings that included religious ceremonies, ritual athletic contests (most notably the Tailteann Games), feasting, matchmaking and trading.
