Before the three-year Sunday cycle, the Gospel on the fourth Sunday of Advent was Luke 3:1-6. In the three-year cycle, the fourth Sunday is either Matthew 1:18-25 (A), Luke 1:26-38 (B), or Luke 1:39-45 (C).
The four Christmas Masses (Vigil, Midnight, Dawn, Day) have the following Gospel readings every year (no matter what form of Mass, EF or OF, you attend):
Vigil: Matthew 1:1-25 (1:18b-21 in the EF; 1:18-25 permitted in the OF)
Midnight: Luke 2:1-14
Dawn: Luke 2:15-20
Day: John 1:1-18 (1:1-14 in the EF; 1:6-8 can be omitted in the OF)
So... why Matthew 1:18-25 two "days" in a row? Because that's how they arranged the calendar in Year A.
