Friday the 13th is a day that can easily strike fear in the hearts of at least an estimated 21million people in the United States, with an estimated $800 million to $900 million that is lost in America's business world annually, according to the Stress Management Center and Phobia Institute in Asheville, N.C.
And it may not be as rare ass one would think. A Friday the 13th is likely to happen every 212 days [on average]. The longest Friday the 13th drought was fourteen months, but a Friday the 13th cannot happen more than three times in a Gregorian calendar year.
Some years, not much happens on a month that has a Friday the 13th. Other years, history is made, for better or worse; one Washingtonian says he doesn't take any chances.
"On Friday the 13th," said Karl Ammons, "I try to stay inside if I can. I don't travel or even go to work. I request the day off days and weeks in advance. I don't have a reason to go out."
So what about D.C.?
History was made on Friday, July 13, 1832, by Henry Rowe Schoolcraft, an early American geologist, geographer and explorer.
He was the first European who discovered the source of the mighty Mississippi River.
Schoolcraft studied Native American cultures and took part in one if the the early explorations of the American Midwest, which led to producing America's first written account of the exploration of the Ozark Mountain region.
What is the link to the District of Columbia?
Schoolcraft was a member of the Michigan Territory legislator, in 1832, and had traveled to the upper reaches of the Mississippi River on behalf of the territory and the federal government. He spoke with members of the Ojibwa and Dakota (Sioux) nations, where it was alleged there was a case of smallpox that originated from the native populations. He discovered that there was no evidence of smallpox among the native people until after visits by the French against the British. While he was there, he took the opportunity to try to find the source of the Mississippi River.

In Italy, Friday the 17th (and not the 13th) is considered a day of bad luck, although one folklore tale states that the origin of Friday the 13th came from Italy with death of Gioachino Rossini. Legend has it that Italians have often looked at Friday as an unlucky day, and 13 as an unlucky number and the notable Rossini died on Friday the 13th surrounded by his friends.
