5. Today in History: Today is Friday the 13th. The superstitution that today is bad luck was first noted in literature in an 1869 biography of Gioachino Rossini who passed away on the taboo date. There are several theories why the 13th is considered unlucky which surround numerology and the stock market crash. In Spain, Tuesday the 13th is the unlucky day. It appears, the superstition is just that; based on pieced-together reports of bad luck with no actual evidence that today is more or less signifigant than any other.
