October 31 sits just about halfway between the Autumnal Equinox in September and the Winter Solstice in December, making it a “cross-quarter day” in the Wheel of the Year.  It has long been the date of the ancient festival of Samhain, which is a Celtic word (pronounced SAW-win), celebrating the end of the harvest and the beginning of the dark half of the year. A day that humans first begin to feel the grip of the growing cold and darkness, in the ancient Gaelic tradition, it’s a “liminal” day, where the veil between the worlds of the living and the dead, or our world and the underworld, is thin.  Catholics created All Saints Day on November 1, and combined it with the October 31 festival, which they called All Hallow’s Eve, or Halloween. The Mexican celebration Dia de los Muertos, or the “Day of the Dead,” also occurs at this time of year, and honors departed loved ones and seeks to support their spiritual journeys. In some traditions, nature goddesses descend on this day to the underworld, not to return again until Spring. Â
