December 16 is the first day of Las Posadas, chiefly celebrated in Latin America. It ends on December 24. “Posada” in Spanish means dwelling and in this case it is the nine-day celebration to represent the nine-month pregnancy of Mary and the journey to Bethlehem.
A couple plays the parts of Mary and Joseph and each night groups of wayfarers go to a house in search of lodging. They are welcomed in to pray the rosary and visit with the householder but must resume their journey the following night until December 24 when there is a final celebration in a church and Jesus is born.
