2024 Immaculate Conception Mass obligation remains in LA, despite date transfer
In years past, when a solemnity fell on a Sunday during Advent, Lent, or Easter, the feast day would be transferred to Monday and Catholics were encouraged, but not obligated, to attend Mass.
But in the case of this year’s solemnity of the Immaculate Conception (Dec. 8), which falls on a Sunday, the day will be observed on Monday, Dec. 9, and remain a Holy Day of Obligation for Catholics in the Archdiocese of Los Angeles.
The decision stems from a clarification issued by the Vatican’s Dicastery for Legislative Texts in response to a request from the U.S. Conference of Catholic Bishops earlier this year asking for guidance on the matter.
