Another Friday the 13th?

Today is the third Friday the 13th of 2012 - and thankfully, the last for the year.

But why is there such a superstition around this date? The fear of Friday the 13th dates back to Roman times, the rationale lost over the centuries. But still it persists.

According to a report in philly.com, the economy is impacted by hundreds of millions of dollars by people who decide to stay home rather than venture out.

Donald Dossey, a behavorial scientist quoted in the report, said as many as 21 million Americans have some fear of Friday the 13th.

Interesting facts:

• In the Gregorian calendar, this day occurs at least once, but at most three times a year.
• Any month's 13th day will fall on a Friday if the month starts on a Sunday.
• The fear of Friday the 13th is called friggatriskaidekaphobia. The term was derived from the name of the Norse goddess, Frigga, which is how Friday got its name.
• A second name has been attributed to this day - triskaidekaphobia - which, says, philly.com - is the irrational fear associated with Friday the 13th.
• In 2011 May was the only month that had a Friday the 13th.
• In 2012, three months will have a Friday the 13th, January, April and July.
• Many buildings even today, do not have a 13th floor.

The good news: It will be another 14 months before the next Friday the 13th rolls around in September 2013.
