Earlier today at the Sunday Angelus in Rome, Pope Francis announced World Day of Grandparents and the Elderly to be held on 4th Sunday of July, the Sunday closest to July 26th feast of Sts. Joachim and Anne, parents of Blessed Virgin Mary, grandparents of Jesus.
The first world day will be July 25, 2021. Eastern Christians, for example the Melkites liturgically recall St Anne’s memory on July 25th.
