All right, brace yourself. Today is Friday the 13th. A day when the fears of superstitious people are heightened and many expect bad things to happen. It's a day when a black cat crossing your path can make you nervous. A day when stepping on a crack could mean breaking your momma’s back. Luckily, for those freaked out by the day, today's the third and final Friday the 13th of 2012. Here's a rundown of some things you might not have known about this "unlucky" day: 

    -13 is considered unlucky because 12 is the number that symbolizes completeness. There are 12 months in a year, 12 hours on a clock. 13 is just past that, which disturbs some people.
    -Some 17 to 21 million people are afraid of Friday the 13th, a condition known as friggatrishtkaidekaphobia. Triskaidekaphobia is the fear of the number thirteen.
    -Approximately $800 to $900 million is said to be lost each Friday the 13th, because of people who fear to transact business, or even get out of bed.
    -Friday the 13th comes around no less than once a year, and no more than three times a year. Before this year, the last triple-header year was 1998.
    -On average, there is a Friday the 13th once every 212 days. Any month’s 13th day will fall on a Friday if the month starts on a Sunday.
