Yes, members of The Church of Jesus Christ of Latter-day Saints, commonly known as the Mormon Church, do celebrate Christmas. Christmas is considered to be a significant holiday for members of the LDS Church, and they observe many of the same traditions as other Christians, such as gift-giving, spending time with family, attending church services, and singing carols. However, some LDS members may have different interpretations or practices related to certain aspects of Christmas, such as the focus on the birth of Christ or the celebration of the holiday in general.
