Happy Yalda, Merry Christmas, Happy Hanukkah, Happy Kwanzaa.
The Yalda festival was a Mithraic celebration, which finds its origins among the earliest Iranians. But in 53 BCE, when Roman legions were unable to conquer Parthian Mithraists, they adopted Mithra the “Unconquered Sun” as their own military deity, and Yalda or “Yule” became an official celebration of the Roman Empire.
Many of the original pagan symbols survive in what has come to be known as Christmas such as: holly, ivy, the color red, the mistletoe, Yule logs, the giving of gifts, decorated evergreen trees, Santa Claus, etc..
Christmas Day (December 25th) is a Christian holiday which is celebrated around the world by decorating Christmas trees, attending church, traditional food, and exchanging gifts.
