The Catholic Church traditionally designates the month of December to commemorate the Advent season.
Advent, derived from the Latin term "ad-venire," meaning "to come to," is the period that includes the four Sundays and the weekdays preceding the celebration of Christmas. The Advent season serves as a period of preparation that focuses our hearts and minds on the anticipated second coming of Christ at the end of time, as well as the celebration of Our Lord’s birth on Christmas.
