St. Joseph's Day is the feast day of Joseph the Betrothed, spouse of Mary and foster-father of Jesus of Nazareth. It is celebrated on March 19th.
- The 12th and 13th of the Divine Praises of the Roman Catholic Church are as follows: "Blessed be the name of Mary, Virgin and Mother. Blessed be Saint Joseph, her most chaste spouse".
However, as Joseph was a carpenter (or a builder), he is also the patron saint of workers. Pope Pius XII decided in 1955 to add the optional feast day of Saint Joseph the Worker on May 1st, intentionally coinciding with the international labour day.
In the Orthodox Church the Feast of Saint Joseph falls on the Sunday after Christmas.
