Posadas are held during the Advent season as a preparation for the season of Christmas, beginning the 16th of December and ending 24th of December. They are a re-enactment of Mary and Joseph searching for lodging in Bethlehem. Las Posadas are a 400-year old tradition from Mexico. It is common to have songs, prayers, the Rosary, and food. At Holy Redeemer, different groups within the parish take turns in leading Posadas.
