The Day of the Dead, or Dia de los Muertos, is anything but a dour affair. Celebrated Oct. 31 through Nov. 2 throughout Mexico, in Yucatán it’s called Hanal Pixán, a Mayan saying that means “food of the souls.” Historically held at the beginning of summer, Day of the Dead was moved to coincide with the Christian festivals following the Spanish colonization of Mexico in the 16th Century. On Oct. 31, All Hallows Eve, children make a children’s altar to invite the angelitos to visit. Nov. 1 is All Saints Day, and the adult spirits are invoked and invited. Nov. 2 is All Souls Day, when families go to the cemetery to decorate the graves and tombs of their relatives. Several streets are closed Saturday for The Paseo de las Ánimas, a newer tradition which has caught fire.
