The First Presidency of The Church of Jesus Christ of Latter-day Saints has announced that because Christmas Day this year falls on a Sunday, the only meeting Church members need to attend that day is sacrament meeting.
The November 10 letter to Church leaders also states that stake and district presidents may consult with bishops and branch presidents to adjust meeting times on December 25 to best accommodate local needs.
In addition, because New Year’s Day on January 1 also falls on a Sunday this year, stake and district presidents may consider setting an alternative Sunday for observing fast day, but other regular meetings will be held. Any New Year’s Eve Church-sponsored socials such as dances or other activities should conclude at midnight on Saturday, December 31.
