“Worldwide Pioneer Heritage Service Day Announced,” Ensign, Apr. 1997, 79
The First Presidency sent out the following letter to all Church priesthood leaders:
“In 1997 the Church will celebrate the 150th anniversary of the arrival of the first Latter-day Saint pioneers in the Salt Lake Valley. The sesquicentennial celebration will also honor pioneers of all times and places who have helped establish the Church throughout the world.
“We have designated Saturday, July 19, 1997, as Pioneer Heritage Service Day and invite each ward and branch to contribute a minimum of 150 hours of community service where possible. As modern-day beneficiaries of the sacrifices made by pioneers who have gone before, we can show our gratitude by unitedly rendering charitable service to others in our communities.
“We encourage priesthood leaders to plan and coordinate local service projects on this day of service.”
