In Mexico, Christmas is celebrated from the December 12th to January 6th.
From December 16th to Christmas Eve, children often perform the 'Posada' processions or Posadas. Posada is Spanish for Inn or Lodging. There are nine Posadas. These celebrate the part of the Christmas story where Joseph and Mary looked for a room in an Inn. For the Posadas, the outside of houses are decorated with evergreens, moss and paper lanterns.
