December 25th has become mainly associated with the birth of Jesus of Nazareth for nearly two-thousand years, especially in the Western world. However, before A.D. 350, December 25th was the birthday of many gods and a holiday for other religions. Also keep in mind that various other religions have adopted December 25th as a holiday over the years. The winter season itself is sacred to many religions world-wide, not just Christianity. Many Christmas traditions, such as the Christmas tree, the mistletoe, and hollyberries, have their origins in pagan religions.
