At the Three Kings Day Parade – “El Did De Los Reyes.” The Holiday Season does not end on New Year’s. Spanish cultures celebrate January 6 as Three Kings Day, otherwise known as The Feast Of The Epiphany. This is the day the three wise men arrive at the manger holding the newly born Christ and lay down their offerings. Children leave boxes of grass for the camels the three wise men are riding the night before and the next morning they awake to a gift left by the wise men in gratitude.
