Dia de los Muertos

Day of the Dead (Spanish: Día de Muertos) is a Mexican holiday celebrated throughout Mexico, in particular, the Central and South regions, and by people of Mexican ancestry living in other places, especially the United States. It is acknowledged internationally in many other cultures. The multi-day holiday focuses on gatherings of family and friends to pray for and remember friends and family members who have died, and help support their spiritual journey.

The holiday is sometimes called Día de los Muertos in Anglophone countries, a back-translation of its original name, Día de Muertos. It is particularly celebrated in Mexico where the day is a public holiday. Prior to Spanish colonization in the 16th century, the celebration took place at the beginning of summer. Gradually it was associated with October 31, November 1 and November 2 to coincide with the Western Christian triduum of Allhallowtide: All Saints' Eve, All Saints' Day, and All Souls' Day.

Traditions connected with the holiday include building private altars called ofrendas, honouring the deceased using sugar skulls, marigolds, and the favourite foods and beverages of the departed, and visiting graves with these as gifts. Visitors also leave possessions of the deceased at the graves.

The Day of the Dead celebrations in Mexico developed from ancient traditions among its pre-Columbian cultures. Rituals celebrating the deaths of ancestors had been observed by these civilisations perhaps for as long as 2,500–3,000 years. The festival that developed into the modern Day of the Dead fell in the ninth month of the Aztec calendar, about the beginning of August, and was celebrated for an entire month. The festivities were dedicated to the goddess known as the "Lady of the Dead", corresponding to the modern La Calavera Catrina.

By the late 20th century in most regions of Mexico, practices had developed to honour dead children and infants on November 1, and to honour deceased adults on November 2. November 1 is generally referred to as Día de los Inocentes ("Day of the Innocents") but also as Día de los Angelitos ("Day of the Little Angels"); November 2 is referred to as Día de los Muertos or Día de los Difuntos ("Day of the Dead").

In Christian Europe, Roman Catholic customs absorbed pagan traditions. All Saints Day and All Souls Day became the autumnal celebration of the dead. Over many centuries, rites which had occurred in cultivated fields, where the souls of the dead were thought to leave after the harvest, to cemeteries.

In many countries with a Roman Catholic heritage, All Saints Day and All Souls Day have evolved traditions in which people take the day off work, go to cemeteries with candles and flowers, and give presents to children, usually sweets and toys. In Portugal and Spain ofrendas ("offerings") are made on this day. In Spain, the play Don Juan Tenorio is traditionally performed. In Belgium, France, Ireland, Italy, the Netherlands, Portugal, and Spain, people bring flowers (typically chrysanthemums in France and northern Europe) to the graves of dead relatives and say prayers over the dead.

As part of a promotion by the Mexican embassy in Prague, Czech Republic since the late 20th century, some local citizens join in a Mexican-style Day of the Dead. A theatre group produces events featuring masks, candles, and sugar skulls.
