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.
