Because it is the 13th day of the month, and it falls on Friday.
The probability is approx 15/16.

If a 31-day month starts on a Friday, Saturday or Sunday it will have 5 Sundays; if not it will have 4. So the probability is 3/7.
There are 4 months that end in the letter Y, January, February, May, and July. The probability, then, of a random month ending in the letter Y is 4 in 12, or 1 in 3, or about 0.3333.
Well..., first you have to be born on the 13th of some month. But your birth-day has to be 13 years before a Friday the 13th in the same month. So the probability is low. It also depends on the month you were born. A very lucky,..AND TRUE..., example is my 13th birthday. I'll turn 13 on Friday the 13th of July in 2012. So...I'm rare. LOW PROBABILITY!!

It's this Friday. (May2011)
Simply look at the 13th of the month on a calendar and see if it is a Friday. A simple rule is that if the 1st of the month is a Sunday, then the 13th will be a Friday.
A month must begin on a Sunday in order to have a Friday the 13th.
Black Friday is the traditional name for the Friday following Thanksgiving in November.
