Day of the Dead 2010 Celebrations Kick Off Internationally (PHOTOS)

For many Roman Catholics around the world, Halloween is officially old news, as many will partake in colorful celebrations today to mark another spooky holiday known as the All Saints' Day or in Mexico, Dia de los Muertos.

Most consider All Saints' Day to be a day of remembrance given in honor of revered saints as well as loved ones who've passed on. But that doesn't mean it's a solemn affair -- in Mexico and other Latin American nations, the celebrations include food, music, lively parades and elaborate costumes. The party usually lasts at least until All Souls' Day on Nov. 2, and has been known to extend to a full week.
