Most saints have specially designated feast days. On those days we remember these holy men and women in a special way. The tradition arose from the early Christian custom of commemorating each martyr annually on the date of his or her death, or birth into heaven, a date therefore referred to in Latin as the martyr's dies natalis ("day of birth"). The Church also celebrates special events or happenings in the history of the Church with solemnities, feasts, and memorials. The saint days and other celebrations in the month of March are: 

March 19 - Saint Joseph, spouse of the Blessed Virgin Mary

March 25 - The Annunciation of the Lord

March 28 - Palm Sunday of the Passion of the Lord
