Day of the Dead (Día de Muertos), a syncretic religious holiday, combining the death veneration rituals of the ancient Aztec culture with the Catholic practice, is celebrated throughout all of Mexico. Based on the belief that the souls of the departed may come back to this world on that day, people gather at the gravesites in cemeteries, praying, drinking, and playing music, to joyfully remember friends or family members who have died and to support their souls on the spiritual journey.
