Friday the 13th is considered an unlucky day in Western superstition. It occurs when the 13th day of the month in the Gregorian calendar falls on a Friday.
The fear of the number 13 has been given a scientific name: "triskaidekaphobia"; and on analogy to this the fear of Friday the 13th is called paraskevidekatriaphobia, from the Greek words Paraskeví (Παρασκευή, meaning "Friday"), and dekatreís (δεκατρείς, meaning "thirteen").
The superstition surrounding this day may have arisen in the Middle Ages, "originating from the story of Jesus' last supper and crucifixion" in which there were 13 individuals present in the Upper Room on the 13th of Nisan Maundy Thursday, the night before his death on Good Friday. While there is evidence of both Friday and the number 13 being considered unlucky, there is no record of the two items being referred to as especially unlucky in conjunction before the 19th century.
An early documented reference in English occurs in Henry Sutherland Edwards' 1869 biography of Gioachino Rossini, who died on a Friday 13th:
Friday the Thirteenth is a live album by the English rock band The Stranglers. To mark the twenty first anniversary of their original recording contract with United Artists Records, they played to a sold out Royal Albert Hall (London, UK) with an eighteen piece string orchestra (the Electra Strings). Friday the Thirteenth presents part of the set (these songs, plus the remainder of the set can be found on the accompanying DVD release). Composer and musician Jocelyn Pook contributions to the songs Waltz in Black,Valley of the Birds, Daddy's Riding the Range, Golden Brown, and No More Heroes.
Friday the Thirteenth is a 1933 British drama film directed by Victor Saville and starring Jessie Matthews, Sonnie Hale and Muriel Aked. The film depicts the lives of several passengers in the hours before they are involved in a bus crash.
