Christian feast day: Michael Hồ Đình Hy (one of Vietnamese Martyrs)

Michael Hồ Đình Hy was a Vietnamese mandarin official who was martyred for his Roman Catholic belief during the persecutions by Emperor Tự Đức. He was canonized in 1988 along with another 116 Vietnamese Martyrs.

Vietnamese Martyrs, also known as the Martyrs of Tonkin and Cochinchina, collectively Martyrs of Annam or formerly Martyrs of Indochina, are saints of the Catholic Church who were canonized by Pope John Paul II. On June 19, 1988, thousands of overseas Vietnamese worldwide gathered at St. Peter's Square for the celebration of the canonization of 117 Vietnamese Martyrs, an event organized by Monsignor Trần Văn Hoài. Their memorial in the current General Roman Calendar is on November 24 as Saint Andrew Dung-Lac and Companions, although many of these saints have a second memorial, having been beatified and inscribed on the local calendar prior to the canonization of the group.
