I thought Samhain was just a name that Glenn Danzig had for the band he started after he split up from the Misfits and before he formed Danzig (the band). Samhain is Gaelic for November. Samhain â€” the Celtic ancestor of today’s Halloween â€” was both the last of the four seasonal celebrations that divided the Celtic year into quarters (see Imbolc, Beltane, and Lughnasa) and the first of their new year. The word samhain means the end of summer, but the time of year meant the beginning of winter. The Celts chose this celebrational but ominous turning point as their New Year.
A modernized version of this festival continues today in some of the traditions of the Catholic All Souls’ Day, the secular Halloween, and in folk practices of Samhain itself in the Celtic Nations and the Irish and Scottish diasporas. It is also observed by various types of Neopagans.
