Before the 20th century, although there is evidence that the Number 13 was considered unlucky, and Friday was considered unlucky, there was no link between them. The first documented mention of a "Friday the 13th" is generally listed as occurring in the early 20th century. Snopes urban legends: Friday the 13th 1 However, many popular stories exist about the origin of the concept:
EFFECTS IN PEOPLE AND CULTURES "It's been estimated that {Link without Title} $800 or $900 million is lost in business on this day because people will not fly or do business they would normally do." This sequence, here given for 2001–2028, repeats every 28 years from 1901 to 2099 . The months with a Friday the 13th are determined by the Dominical Letter (G, F, GF, etc.) of the year. Any month that begins on a Sunday will contain a Friday the 13th. Every year has at least one and at most three Fridays the 13th, with 48 occurrences in 28 years an average of 1.7 times per year. The reason this is this evidence: twenty-eight years have 336 months and 336 also equals seven times forty-eight. The Gregorian Calendar 400-year cycle contains 146,097 days. Along with the 146,000 normal days, there are ninety-seven February 29 s (also called " Leap Year Days"). The easiest way to explain how and why the Gregorian Calendar rotates during any 400-year cycle is that there are 365 days every year. Ninety-seven of the 400 years are leap years, which have 366 days. Years with 365 days have 52 weeks, with one additional day; years with 366 days have 52 weeks, with two additional days. Adding the "additional days" over the 400-year period results in 497 total "additional days". These 497 days total exactly seventy-one weeks. Thus, the total number weeks in the Gregorian Calendar cycle is 20,871.
The distribution of the 13th day of the 4,800 months is as follows: There are 4,800 months in 400 years, so the 13th of the month occurs 4,800 times in this interval. The number of times the 13th occurs on each weekday is given in the table above. As shown by Brown (1933), the thirteenth of the month is slightly more likely to be on a Friday than on any other day.
