Heptadecaphobia

Heptadecaphobia is a fear of the number 17. The word "heptadeca" in Ancient Greek hepta meaning "seven", and deca meaning "ten". The fear may have originated from Italy, where 17 is considered the unlucky number. Italy is also where the Roman numeral was patented, which the Roman numeral for 17 is XVII, which is meant to be translates to VIXI, the Latin word for "I have lived", which in the perfect sense means to "my life is over". Some horrible days on the 17th of the month, e.g. having really bad day on January 17, then February 17, and so on. The unluckiness of the number 17 may not be that surprising as it is the sum of 4 (the unlucky number in several Asian countries including China and Japan) and 13 (the unlucky number over much of the world).

Heptadecaphobia of Osiris
The fear can also be originated from mythology where Osiris died on the 17th day of the month. These imply that the number 17 may believably be a death number. Some sufferers would have their fears enhanced when full moon occurred on the 17th of the month, which the legend goes back to the death of Osiris during the full moon. Those sufferers would only fear the full moon when falling on the 17th while only fearing the number when full moon falls on it.
