Their main Christmas celebration is called La Posada, which is a religious procession that re-enacts the search for shelter by Joseph and Mary before the birth of Jesus.
During the procession, the celebrants go from house to house carrying the images of Mary and Joseph looking for shelter.
Santa Claus is not predominant, but the bright red suit is represented in the traditional flower of the season. This flower is the poinsettia, which has a brilliant red star-shaped bloom. It is believed that a young boy walking to the church to see the nativity scene showing the birth of Jesus realised on the way that he had no gift to offer the Christ child so he gathered up some plain green branches as he walked in he was laughed at but upon placing the branches near the manger they started to bloom a bright red poinsettia flower on each branch.
The Mexican children receive gifts. On Christmas day they are blindfolded and taken to try and break a decorated clay piñata that dangles and swings at the end of a rope. Once the piñata has been broken, the children clamber to recover the candy that was inside the piñata. Those children who have been good, also receive a gift from the Three Wise Men on January 6.
Mexicans attend a midnight mass service which is called la Misa Del Gallo or “the rooster’s mass,” and at the mass they sing lullabies to Jesus.
