Samhain in the Northern Hemisphere and Beltane in the Southern Hemisphere

Samhain marked the Celtic New Year, the end of summer, and the end of the harvest season. It also signaled the beginning of winter, which they associated with death. On this day, the Celts believed the veil between the living and the dead was especially thin. This allowed spirits of the dead to visit the living.

For the Celts, who lived during the Iron Age in what is now Ireland, Scotland, the U.K. and other parts of Northern Europe, Samhain (meaning literally, in modern Irish, “summer's end”) marked the end of summer and kicked off the Celtic new year.
