Easter Sunday (Domingo de Pascua)
Celebrated around late-March/early April
It's a day of both devotion and relaxation after an intense week. The agenda is short: attend Mass, watch the "Burning of the Traitor" and go home to eat a large traditional Easter meal with family. About noon, if you are on Calle San Francisco, you will see, Judas, "the Traitor", along with effigies of other unpopular politicians and well known figures strung up and then ceremoniously blown up. It's rather amusing, as you can see here.
