Catholics around the world celebrate the Day of the Dead around November 2 in connection with the holy days of All Saints' Day and All Souls' Day. All Souls' Day is a day to remember the souls of people who have died. Rituals include the offering of mass for the dead, visiting family graves and commemorating lost loved ones. In Mexico, the Day of the Dead is an event when people hold candlelight vigils and leave food out for deceased relatives.
