Samhain is a pagan religious festival originating from an ancient Celtic spiritual tradition. In modern times, Samhain (a Gaelic word pronounced “sow-win”) is usually celebrated from October 31 to November 1 to welcome in the harvest and usher in “the dark half of the year.” Celebrants believe that the barriers between the physical world and the spirit world break down during Samhain, allowing more interaction between humans and denizens of the Otherworld.

Ancient Samhain

Ancient Celts marked Samhain as the most significant of the four quarterly fire festivals, taking place at the midpoint between the fall equinox and the winter solstice. During this time of year, hearth fires in family homes were left to burn out while the harvest was gathered.
