Known as Dia de los Muertos in Mexico and the Mexican-populated areas of the US, this holiday dates back to the times of the Aztecs, when they celebrated Mictecacihuatl (The Lady of the Dead). The celebration of Day of the Dead focuses on remembering and honoring friends and relatives that have died.
Dia de los Muertos is celebrated every year on November 1st and 2nd, during which time it is believed the spirits of the dead return to visit the living. People buy toys and traditional sweets for the dead children and different alcoholic drinks for the deceased adults. They build shrines on the tombs and plce the trets there so the dead can consume the spirit of the foods. Even though they are eventually consumed by the living, the foods are believed to have no nutritional value.
