Legend: Friday the 13th is a day fraught with peril. Origins: Although most of us would probably affirm that superstition's role in Western culture is now a much diminished one, more a source of amusement than anything else, there are still those who allow their trepidation over particular days or dates to prevent them from engaging in their choice of activities. We may make jokes about Friday the 13th and only kiddingly instruct loved ones to exercise greater care on that day, but those who suffer from a fear of the number thirteen (triskaidekaphobia) or a fear of Friday the 13th (paraskevidekatriaphobia) may genuinely feel limited by the rumored potential for ill luck connected with the date. The reasons why Friday came to be regarded as a day of bad luck have been obscured by the mists of time some of the more common theories link it to a significant event in Christian tradition said to have taken place on Friday, such as the Crucifixion, Eve's offering the apple to Adam in the Garden of Eden, the beginning of the Great Flood, or the confusion at the Tower of Babel. Chaucer alluded to Friday as a day on which bad things seemed to happen in the Canterbury Tales as far back as the late 14th century ("And on a Friday fell all this mischance"), but references to Friday as a day connected with ill luck generally start to show up in Western literature around the mid-17th century: Another Friday of 13th in this year is March and November.
