Immaculate Conception, December 9

Immaculate Conception, December 9 – This Solemnity is transferred to Dec. 9th this year because the Second Sunday of Advent falls on Dec. 8th. Although the Solemnity is transferred, the obligation to attend Mass does not transfer. Therefore, the Immaculate Conception is not a holy day of obligation this year but the celebration of a parish Mass on this day is still encouraged.
