A sprite-like character with roots in Viking lore. Jack is a variant of Old Man Winter and is held responsible for frosty weather, autumn colors and fern-like patterns on cold windows. Though unconnected to Christianity, he is sometimes hijacked for modern secular Christmas entertainment, such as Frosty’s Winter Wonderland, a 1976 Rankin/Bass production.
Welcome to the winter solstice (the original reason for this holiday season). Today is the shortest day of year.
