Friday the 13th occurs when the thirteenth day of a month falls on a Friday, which superstition holds to be a day of bad luck. In the Gregorian calendar, this day occurs at least once, but at most three times a year. Any month’s 13th day will fall on a Friday if the month starts on a Sunday.
The fear of Friday the 13th is called friggatriskaidekaphobia (Frigga being the name of the Norse goddess for whom “Friday” is named and triskaidekaphobia meaning fear of the number thirteen), or paraskevidekatriaphobia a concatenation of the Greek words Paraskeví (Παρασκευή, meaning “Friday”), and dekatreís (δεκατρείς, meaning “thirteen”) attached to phobía (φοβία, from phóbos, φόβος, meaning “fear”). The latter word was derived in 1911 and first appeared in a mainstream source in 1953.
Fear of the number 13—aka, triskaidekaphobia goes back to a Norse myth about 12 gods having a dinner party at Valhalla, Norse mythology’s heaven. In walked the uninvited 13th guest, the mischievous god Loki. Once there, Loki arranged for Hoder, the blind god of darkness, to shoot Balder the Beautiful, the god of joy and gladness, with a mistletoe-tipped arrow. Balder died, and the whole Earth got dark. The whole Earth mourned. It was a bad, unlucky day.
It’s well known among Christians as the day Jesus was crucified. Also, some biblical scholars believe Eve tempted Adam with the forbidden fruit on Friday. Perhaps most significant is a belief that Abel was slain by his brother Cain on Friday the 13th. Meanwhile, in ancient Rome, witches reportedly gathered in groups of 12. The 13th was believed to be the devil.
Thomas Fernsler, an associate policy scientist in the Mathematics and Science Education Resource Center at the University of Delaware in Newark, said the number 13 suffers because of its position after 12. According to Fernsler, numerologists consider 12 a “complete” number. There are 12 months in a year, 12 signs of the zodiac, 12 gods of Olympus, 12 labors of Hercules, 12 tribes of Israel, and 12 apostles of Jesus, he pointed out.
Triskaidekaphobia’s Architectural Effects
Triskaidekaphobia can be seen even in how societies are built. More than 80 percent of high-rise buildings lack a 13th floor. Many airports skip the 13th gate. Hospitals and hotels regularly have no room number 13.
On streets in Florence, Italy, the house between number 12 and 14 is addressed as 12 1/2. In France socialites known as the quatorziens (“fourteeners”) once made themselves available as 14th guests to keep a dinner party from an unlucky fate.
DePauw University’s Dudley said nobody really knows why Friday the 13th has spawned so many superstitions. “You’ve got to have something that is unlucky, and somehow they hit on 13,” he said. “But all these explanations are just moonshine.”
