In most regions of Mexico, November 1st honors children and infants, whereas deceased adults are honored on November 2nd. This is indicated by generally referring to November 1st mainly as Día de los Inocentes ("Day of the Innocents") but also as Día de los Angelitos ("Day of the Little Angels") and November 2nd as Día de los Muertos or Día de los Difuntos ("Day of the Dead").
People go to cemeteries to be with the souls of the departed and build private altars containing the favorite foods and beverages as well as photos and memorabilia of the departed. The intent is to encourage visits by the souls, so that the souls will hear the prayers and the comments of the living directed to them. Celebrations can take a humorous tone, as celebrants remember funny events and anecdotes about the departed.
In some parts of the country (especially the cities, where in recent years there are displaced other customs), children in costumes roam the streets, knocking on people's doors for a calaverita, a small gift of candies or money; they also ask passersby for it. This custom is similar to that of Halloween's trick-or-treating and is relatively recent.
There are traditions all over the world that celebrate the 'Day of the Dead' and whichever way you celebrate it, I hope that you are blessed with happy memories of those loved ones that have gone before you.
