Create a Pagan Winter Solstice framework for the entire holidays season - understand that Christmas Eve and Christmas, New Year's Eve and New Year's Day have their origins in Winter Solstice celebrations of a variety of Pagan cultures through the ages.
The Winter Solstice is the shortest day and the longest night of the year. The dark wins but only briefly. From now on, the nights get shorter & the days grow longer. Many of the customs associated with Winter Solstice (& other midwinter festivals such as St Lucy’s Day, Saturnalia, Hanukkah & Twelfth Night) derive from stories of a mighty battle between dark & light, which is won, by the light. Other traditions say this is the time a savior (the Sun Child) is born to a virgin mother.
