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 September are: 

September 3 - Saint Gregory the Great, pope and doctor of the Church

September 9 - Saint Peter Claver, priest

September 13 - Saint John Chrysostom, bishop and doctor of the Church
