Friday the 13th is a date considered to be bad luck in most of North American. Although most experts agree, there is no real evidence to support a “Friday the 13th” superstition and no real cause to fear the date.
The fear of Friday the 13th has been called friggatriskaidekaphobia (Frigga being the name of the Norse goddess for whom “Friday” is named and triskaidekaphobia meaning fear of the number thirteen).
The Dutch Centre for Insurance Statistics (CVS), stated that “fewer accidents and reports of fire and theft occur on Friday the 13th than on other Fridays, because people are preventatively more careful. Statistically speaking, driving is slightly safer on Friday the 13th.
