The Day of the Dead, or Día de los Muertos, is a multi-day holiday celebrated on November 1 and 2 to honor and remember deceased loved ones. Celebrated primarily in Mexico and parts of Latin America, it involves families gathering to celebrate the lives of those who have passed, often through creating altars, decorating graves, and sharing memories. November 1 is for remembering deceased children and November 2 is for remembering deceased adults.
