Día de los Reyes.

Three Kings Day is celebrated on January 6th, twelve days after Christmas. It is often viewed as the last day of the Christmas season (the end of the 12 days of Christmas).

Also known as The Epiphany, Three Kings Day (Día de los Reyes) is a Christian celebration that commemorates the Biblical story of the three kings who followed the star of Bethlehem to bring gifts to the
Christ child. According to the Biblical story, the Three Kings – named Melchior, Caspar and Balthazar – presented the Baby Jesus with gifts of gold, frankincense and myrrh.

Traditionally in Mexico, Three Kings Day was the gift-giving time, rather than Christmas day. Just as it is common for children to leave cookies for Santa in the U.S., in some regions of Mexico, it was customary for children to leave their shoes out on the night of January 5, often filling them with hay for the camels, in hopes that the Three Kings would be generous. Mexican children would awake on January 6 to find their shoes filled with toys and gifts.

Also traditional in Mexico is for families to gather together and share the Rosca de Reyes. The Rosca de Reyes is a crown-shaped sweet bread decorated with pieces of orange and lime. It is filled with nuts, figs, and cherries. Hot chocolate is traditionally served with the Rosca de Reyes.
