Samhain (pronounced Sow-en) is the primary Celtic festival, celebrated on the evening of October 31st–November 1st. It focuses on our links to our spiritual and physical ancestors. The honoring of ancestors is a concept celebrated world-round under a number of different names.
During Samhain, the veils between the world of spirit and the world of mortals are at their thinnest. This is the time of year when the dead roam the earth.
Samhain is considered the third harvest, or meat harvest (Lughnasadh being the first–or grain harvest, and Mabon being the second–or fruits harvest).
