The epiphany is the manifestation of Christ to the Gentiles as represented by the Magi. Another name for the Epiphany is the Theophany. This day was the recognition of the manifestation of Christ to the gentiles in the persons of the magi. This day is normally celebrated the twelfth day after Christmas.
In Spain, on the day of the Epiphany, all of the children get to write a letter to the Three Kings. They write what they want the three kings to bring them. On Christmas Day in Spain some families do not always exchange gifts. On the other hand, for almost all families in Spain is a day to exchange gifts on the day of the Epiphany. On the day before the Epiphany, January 5, kids or adults leave milk of wine out for the three kings. Just like Christmas, kids wake up with a bunch of joy, and there are presents all around the tree. The breakfast that they eat on this day is called "Roscón de Los Reyes". The Roscón is a donut sweetbread with candied fruits. The cool thing about this breakfast is that inside of the Roscón is a figurine of baby Jesus, and whoever finds the figurine of Jesus first is considered "king" or "queen" of the house of the day.
