Our ancestors lived in a world where everyone believed in mystery and magic. Every year, they gathered together to celebrate the seemingly miraculous return of the light after the longest night of the year and that's how Winter Solstice festivals were born. To this day, people all over the world celebrate Winter Solstice as a time of rebirth, a new beginning and a chance to marvel at the power of transition from darkness into light.
Ancient Solstice festivals were the last big feasts before the depths of winter - when food would become scarce. Many modern holiday traditions like Christmas, Hanukkah, Kwanzaa and New Year's were borrowed from ancient Solstice celebrations. Cultures throughout the world still have winter festivals that include lights and large fires, feasting, dancing and singing, and closeness with loved ones. As they did long ago, these activities help to reinvigorate us in the cold and darkness.
