Beltane is the anglicised name for the Gaelic May Day festival. Most commonly it is held on 1 May, or about halfway between the spring equinox and the summer solstice. Historically, it was widely observed throughout Ireland, Scotland and the Isle of Man. In Irish the name for the festival day is Lá Bealtaine , in Scottish GaelicLà Bealltainn and in Manx GaelicLaa Boaltinn/Boaldyn. It is one of the four Gaelic seasonal festivals—along with Samhain, Imbolc and Lughnasadh—and is similar to the Welsh Calan Mai.
