Three Kings’ Day, Spain On January 6, Three Kings’ Day is celebrated in much of the Spanish-speaking world, marking the occasion when three wise men visited the baby Jesus on the twelfth day of Christmas, bringing gifts of gold, frankincense and myrrh. In Spain, Dia de los Reyes, as it’s known, is all about massive parades and roscon de reyes , a sweet, ring-shaped pastry meant to resemble a king’s crown. The pastry traditionally contains a small plastic figure, granting the finder royal status for the day. The pastry also conceals a bean, burdening the finder with the task of buying next year’s cake.
