Immaculate Conception – Mass

In keeping with the practice of the Holy See that each country observe a Solemnity of Mary, the USCCB chose to observe the Solemnity of the Immaculate Conception of the Blessed Virgin Mary as a holy day of obligation since under this title Mary is the Patroness of the U.S.A. Thus, even though the Solemnity of the Immaculate Conception of the Blessed Virgin Mary falls on a Saturday this year, it is to be observed as a holy day of obligation.
