First Sunday of Advent is a Sunday of Advent in the Roman Rite, celebrated as a principal observance of the Lord's Paschal Mystery.[1]
Place in the calendar
It begins Advent and the new Roman liturgical year on the Sunday falling from 27 November through 3 December.
Its exact civil date is determined each year by the temporal cycle and the date of Easter or Christmas, as applicable.
Mystery celebrated
The Church watches for the Lord's return and begins the immediate preparation for the celebration of his Nativity.
The proper prayers and the readings appointed for Years A, B, and C express the celebration within the one Paschal Mystery of Christ.[2]
