Samhain is a Gaelic festival marking the end of the harvest season and beginning of winter or "darker-half" of the year. It is held on 1 November but with celebrations beginning on the evening of 31 October, since the Celtic day began and ended at sunset. This is about halfway between the autumn equinox and winter solstice. It is one of the four Gaelic seasonal festivals along with Imbolc, Beltaine and Lughnasa. Historically it was widely observed throughout Ireland, Scotland, and the Isle of Man. A similar festival was held by the Brittonic Celtic people, called Calan Gaeaf in Wales, Kalan Gwav in Cornwall and Kalan Goañv in Brittany.
