Just after trick-or-treaters enjoy Halloween in the United States, Mexican families observe the Day of the Dead, which celebrates both life and death. Rooted in the Christian remembrances on All Saints’ Day and All Souls’ Day, and in two Aztec festivals centered on welcoming the souls of the dead who merrily returned each year to visit their living relatives, the holiday features vibrant costumes, colorfully decorated skulls, parades, and special meals.
