is a Gaelic festival marking the end of the harvest season and beginning of winter or "darker half" of the year. It is also the Irish language name for November. Celebrations begin on the evening of 31 October or 30 April (in the Southern Hemisphere), since the Celtic day began and ended at sunset.. This is about halfway between the autumnal equinox and winter solstice. It is one of the four Gaelic seasonal festivals along with Imbolc, Bealtaine, and Lughnasa. Historically it was widely observed throughout Ireland, Scotland, Wales and the Isle of Man. A similar festival is held by the Brittonic Celtic (Gaul) people
As we mark the end of the harvest season. It is the end of the Celtic year when the Holly King defeats the Oak King "The Bringer of Light" and the beginning of winter or the "darker half" of the year. We burn the Harvestman in honor of the fallen Oak King as a symbolic funeral. " Out of the Ashes he will be reborn."
