Article: Carnival means weeks of events that bring colourfully decorated floats, contagiously throbbing music, luxuriously costumed groups of celebrants of all ages, King and Queen elections, electrifying jump-ups and torchlight parades, the Jouvert morning: the Children's Parades and finally the Grand Parade. Aruba's biggest celebration is a month-long affair consisting of festive "jump-ups" (street parades), spectacular parades and creative contests. Music and flamboyant costumes play a central role, from the Queen elections to the Grand Parade. Street parades continue in various districts throughout the month, with brass band, steel drum and roadmarch tunes. On the evening before Lent, Carnival ends with the symbolic burning of King Momo.

Now answer this question: When is King Mom symbolically burnt?
