Saint Joseph's Day, March 19, the Feast of St. Joseph is in Western Christianity the principal feast day of Saint Joseph, Spouse of the Blessed Virgin Mary.^[1] It has the rank of a solemnity in the Roman Catholic Church; Catholics who follow the Missal of 1962 celebrate it as a first class feast. Previous to 1962 it was celebrated as a feast of the rank of double of the first class. It is a feast in the provinces of the Anglican Communion, and a feast or festival in the Lutheran Church. Saint Joseph's Day is the Patronal Feast day for Poland as well as for Canada, persons named Joseph, Josephine, etc., for religious orders, schools and parishes bearing his name, and for carpenters. It is also Father's Day in some Catholic countries, mainly Spain, Portugal, and Italy.

March 19 was dedicated to Saint Joseph in several Western calendars by the tenth century, and this custom was established in Rome by 1479. Pope St. Pius V extended its use to the entire Roman Rite by his Apostolic Constitution Quo Primum (July 14, 1570). Since 1969, Episcopal Conferences may, if they wish, transfer it to a date outside Lent.^[2]
