That's a good question. Jehovah's Witnesses are a religious denomination that follows the teachings of the Bible, and they have a different perspective on Christmas than many other Christians. Jehovah's Witnesses believe that Christmas is a secular holiday that has become too commercialized and has lost its true meaning. They also believe that Christmas has pagan roots and that it conflicts with their beliefs in being separate from the world. So, Jehovah's Witnesses do not celebrate Christmas.
