The First Saturday of Each Month we honor Our Lady with a votive Mass and special devotions after Mass.

On the first Saturday of a month, the Mass of the Immaculate Heart of the Blessed Virgin Mary may be said as a votive Mass of the 3rd class in churches and oratories where special exercises of piety in honor of the Immaculate Heart of the Blessed Virgin Mary are actually held on that day.
