'El Día de Los Tres Reyes Magos' is the Three
Wise Kings' Day, Ade. If you look up 'magos' in a Spanish/English dictionary you will see 'magic' as the translation, however in this case it is just the word 'magi' being Spanishized, as there is no Spanish (or English, for that matter) translation of magi.
We do, of course, have the word magic which more than likely derives from magi, which came to mean some mysterious, wise, man who possessed (supposed) fanciful powers. Are you still with me ?
