Well, the wise men didn't get there until Jan 6th - or at least that is the way it is down here. It is the main day for giving gifts to children and the holiday is named after the 3 kings. I think in English it is Epiphany. So, seems you have until then to load up the manger
I have tamales and ponche (a non alcoholic hot fruit punch) that are traditionally served at the posadas.
