The Catholic Church has dedicated numerous feast days throughout the year to events in the life of Mary and her various titles. The following are some of the feasts of Mary in the month of May:
Feast of Our Lady of the Most Blessed Sacrament (May 13): Mary was called Our Lady of the Most Blessed Sacrament by St. Peter Julian Eymard in 1868. In 1905, St. Pius X granted an indulgence to those who prayed to Our Lady of the Most Blessed Sacrament. The Vatican in 1921 designated May 13 as her feast day (but the celebration is not on the church's universal calendar).
Feast of Our Lady of Fatima (May 13): This feast commemorates the first of six apparitions of Mary to three shepherd children at Fatima in Portugal on May 13, 1917. The feast has become a cultural celebration for Portuguese Catholics around the world and is celebrated in many parishes throughout the United States, often with a procession through the streets surrounding the church.
Feast of Mary, Help of Christians (May 24): After praying to Mary for his safe release from captivity when taken prisoner by the French, Pope Pius VII instituted this feast day in 1815. The feast venerates Mary for her intercession on behalf of those who pray to her. Many Catholics will traditionally mark this day by performing their own charitable deeds to help others in need.
Feast of the Visitation (May 31): Originally celebrated in July, the feast of the Visitation marks Luke's Gospel account of Mary, having been told by the Angel Gabriel that she would bear the son of God, visiting her cousin Elizabeth. The feast, which originated in the 13th century, was transferred to its current date in 1969 after the feast of the Queenship of Mary, previously celebrated on May 31, was moved to Aug. 22 to follow the feast of the Assumption.
