why jehovah's don't celebrate christmas

Not all Jehovah's Witnesses observe Christmas in the traditional sense, as it is not part of their religious beliefs. The Jehovah's Witness organization, also known as the Watchtower Bible and Tract Society, discourages its members from celebrating Christmas because it is not mentioned in the Bible and is seen as a pagan holiday that has been commercialized and secularized. Instead, they focus on celebrating the birth of Jesus at other times of the year and encourage members to avoid the materialistic and consumerist aspects of the holiday.
