World Day for Grandparents and the Elderly 
- In 2021, Pope Francis established the celebration of the World Day for Grandparents and Elderly on the fourth Sunday of July, near the liturgical memorial of Saints Joachim and Anne, the grandparents of Jesus (July 26). 
 - The theme for the 2025 celebration selected by the pope is “Blessed are those who have not lost hope” (cf. Sir 14:2).
 - The U.S. bishops have approved moving the celebration of the World Day for Grandparents and the Elderly to the first weekend after Labor Day—September 6 and 7, 2025—to align with National Grandparents (and the Elderly) Day in the United States, as many local communities, schools, and parishes have celebrated for some time.
 - Pastoral Note: You may want to invite grandparents or the elderly people to offer up the gifts of bread and wine during the Offertory.
 - See Book of Blessings Ch. 12 "Order of Blessing of Elderly People Confined to their Homes." Section B "Order of Blessing within Mass."
