The idea of Yule has changed over the centuries. Originally, it was the "time of no season". There were really no "actual" months of the year. There was "planting season" and "harvest season". Yule lasted for twelve "day lights", and no work was done out of doors. It was the time when the Earth was "dead", but after the time of "no season", there was gradually more "Daylight". Not so much a celebration of the return of the Sun, more like a waiting period.During the twelve days of Yule there was certainly lots of eating and drinking. And there was a Yule log; a real tree that was supposed to burn for twelve days and nights. With the rise of Christianity, Yule became "blended" with the feast of the Roman God, Mithras, and then became blended into Christmas. But even the early Christians kept Yule "different" from Christmas, and began the practice of observing Yule a few days before "the birth of Christ." At the present time Yule is just a few days before Christmas; but the twelve days were still kept for Christmas.
Oh, well! Time changes everything!
