The fear of Friday the 13th is called paraskavedekatriaphobia a specialized form of triskaidekaphobia, a phobia (fear) of the number thirteen.

Despite our well-developed brains, our complex technologies and centuries of scientific progress, the human race remains a fearful, superstitious people from ancient times to modern day prophecies - and across all cultural divides.

Friday the 13th superstitions originated in a Norse myth about twelve gods having a feast in Valhalla. The mischievous Loki crashed the party as an uninvited 13th guest and arranged for Hod, the blind god of darkness, to shoot Baldur, the god of joy and gladness, with a mistletoe-tipped arrow. Baldur was killed and the Earth was plunged into darkness and mourning as a result.

Frigg

'Friday' was named after Frigg (or Frigga), the Norse goddess of
marriage, prophecy, clairvoyance and motherhood.

Freya

Later she was confused with the goddess of love, Freya, who in turn became identified with Friday. When the Norsemen and Germanic tribes became Christians, Freya was supposed to have been banished to the mountains as a witch. Friday came to be called 'witches' Sabbath. It was believed that on this day, each week, twelve witches and the Devil met - thirteen evil spirits in all.

Another theory about the origin of this superstition takes us to the arrest of Jacques de Molay, Grand Master of the Knights Templar and 60 of his senior knights, on Friday, October 13, 1307, by King Philip IV of France. That day thousands of Templars were arrested and subsequently tortured. They then 'confessed' and were executed. From that day on, Friday the 13th was considered by followers of the Templars as an evil and unlucky day.

This idea discounts the use of toes or other body parts in counting.
