holiday in the Roman Catholic calendar that falls on November 2. The Roman Catholic Church sets aside All Souls' Day to remember members of the faith who have died, especially those believed to be suffering in purgatory. Through prayers, masses, and almsgiving, the living pay tribute to the dead and hope to help them enter into heaven.
Many ceremonies honoring the dead have taken place throughout history, but it is believed that the abbot Odilo of Cluny, France, originated the annual November 2 commemoration near the end of the 10th century. The practice spread to most other countries by the end of the 13th century. All Saints' Day, which honors saints and martyrs, had been celebrated on November 1 since at least the 9th century, so Odilo chose the following day to remember those whose souls need assistance in becoming worthy of heaven.
In 1915, Pope Benedict XV gave permission for priests to celebrate three masses on All Souls' Day, making it the only other day besides Christmas with that distinction. Churches typically are decorated in black, the color most often associated with death. Parishioners commonly light candles in memory of loved ones and sometimes write the names of the departed in a special commemorative book.
November 2 is celebrated in Mexico and in some areas of the southwestern United States as Día de Los Muertos, or the Day of the Dead. Popular belief holds that spirits are given permission to visit their earthly friends and relatives on this day. Cemeteries are crowded with people picnicking and adorning graves with marigolds, incense, and candles. Households set up festive altars welcoming the departed with foods such as tamales, chili sauces, and flan. People commonly make or buy pan de Los Muertos (bread of the dead), bread decorated with death symbols. Children enjoy chocolate and other sweets molded into shapes such as skulls and caskets.
