I had a recent Yuletide post , too instead of christmas on one of my pages. Just a short version of documentary about how Christmas celebration came about and how it turned out and became a good marketing season. It is also interesting how it is pointed out that Jesus' birthday on the 25th of December was actually not found on record anywhere. In looking at the history, one will find it's way back to how it's just been conveniently set by earlier Christians to fit in and incorporate it to the Yule celebration.
