What holy days of obligation fall during the Advent and Christmas seasons?
In the United States, the feast of the Immaculate Conception, December 8, is a holy day of obligation. Mary is the patroness of the U.S. under this title. The others are Christmas Day, December 25, and Mary, Mother of God, January 1. In years when January 1 falls on either Saturday (as it does in 2005) or Monday the obligation is lifted.
