Solemnity of the Immaculate Conception, Transferred—
This year, December 8 falls on a Sunday, which is also the Second Sunday of Advent. Since the Sundays of Advent are of a higher rank in the Table of Liturgical Days, this year, in the U.S., the Solemnity of the Immaculate Conception is transferred to Monday, December 9, 2019. The day retains the rank of Solemnity (with Creed and Gloria); however it is not a holy day of obligation this year. So, as usual, there will not be Mass here on that Monday.
