friggatriskaidekaphobia
A morbid, irrational fear of Friday the 13th.
Friday is Frigga's Day. Frigga (Frigg) was an ancient Scandinavian fertility and love goddess, equivalent to the Roman Venus who had been worshipped on the sixth day of the week. Christians called Frigga a witch and Friday the witches' Sabbath; modern Wiccans are happy to oblige.
