World Festivals of the Dead
October 30 2008

Throughout the world, festivals of the dead are celebrated after the fall harvest and may last one to three days and even as long as a month.
According to Wikipedia:
In the Japanese Buddhist custom to honor the departed (deceased) spirits of one's ancestors it is known as Bon Festival.
All Souls' Day is also known as the Feast of All Souls, Commemoration of all the Faithful Departed. In Portugal, Spain and Mexico, ofrendas (offerings) are made on this day. In Spain, the play Don Juan Tenorio is traditionally performed. In Belgium, France, Hungary, Italy, Malta, Portugal and Spain people bring flowers to the graves of dead relatives.
In Poland, the Czech Republic, Sweden, Finland, Slovenia, Slovakia, Lithuania, Croatia, Austria, Romania, Hungary and Germany, the tradition is to light candles and visit the graves of deceased relatives. Its origins can be traced to the times of Slavic mythology.
In the Philippines, this day is observed as All Souls' Day. This day and the one before and one after it is spent visiting the graves of deceased relatives, where prayers and flowers are offered, candles are lit and the graves themselves are cleaned, repaired and repainted.
In English-speaking countries, the festival is traditionally celebrated with the hymn "For All the Saints" by William Walsham How. The most familiar tune for this hymn is Sine Nomine by Ralph Vaughan Williams.
In the 21st century the European calendar marks the celebrations of Halloween, All Saints and All Souls' Day as three different events. In many cultures the single event of Festival of the Dead lasting up to 3 days, was held at the end of November and beginning of October; such as those by the Peruvians, the Hindus, the Pacific Islanders, the people of the Tonga Islands, the Australians, the ancient Persians, the ancient Egyptians, the Japanese, ancient Romans, and the northern nations of Europe.
The Day of the Dead (Día de los Muertos in Spanish) is a holiday celebrated mainly in Mexico and by people of Mexican heritage (and others) living in the United States and Canada. The holiday focuses on gatherings of family and friends to pray for and remember friends and relatives who have died. The celebration occurs on the 1st and 2nd of November, in connection with the Catholic holy days of All Saints' Day and All Souls' Day which take place on those days. Traditions include building private altars honoring the deceased, using sugar skulls, marigolds, and the favorite foods and beverages of the departed, and visiting graves with these as gifts. Scholars trace the origins of the modern holiday to indigenous observances dating back thousands of years, and to an Aztec festival dedicated to a goddess called Mictecacihuatl (known in English as "The Lady of the Dead").
Halloween is very popular in Ireland, where it originated, and is known in Irish as Oíche Shamhna (pron: ee-hah how-nah), literally "Samhain Night". Pre-Christian Celts had an autumn festival, Samhain, "End of Summer", a pastoral and agricultural "fire festival" or feast, when the dead revisited the mortal world, and large communal bonfires would hence be lit to ward off evil spirits.
Certain popular beliefs connected with All Souls' Day are of pagan origin and immemorial antiquity. Thus the dead are believed by people in many Catholic countries to return to their former homes on All Souls' Night and partake of the food of the living. In Tyrol, cakes are left for them on the table and the room kept warm for their comfort. In Brittany, people flock to the cemeteries at nightfall to kneel, bareheaded, at the graves of their loved ones, and to anoint the hollow of the tombstone with holy water or to pour libations of milk on it. At bedtime, the supper is left on the table for the souls.
In Bolivia, many people believe that the dead eat the food that is left out for them. Some claim that the food is gone or partially consumed in the morning.
In Inca religion the entire month of November is Ayamarca, which translates to Festival of the Dead.
