Friday, 13th.....

Alhamdullillah, Friday comes again. Yes, Friday, 13th. Yesterday, I read about this date is some what  believed to be a day of bad luck. What a very .......superstition!  I take a look at this year (2012)  calendar and guess what, there are three other days that sharing 13th on Friday that were January, Afril and July. Logically, is it true during these dates a bad luck will overcome us?
Thus, I get these from http://www.timeanddate.com:

Many parties, some with themes similar to Halloween, are celebrated on Friday 13.

Some charities use Friday 13 to hold fund raising events. Friday 13 is a big celebration for motorcyclists at Port Dover in Ontario, Canada. PD13, as it’s called, attracts large crowds.

Friday 13 in August is considered unluckier than any other Friday 13 in Brazil, especially as agosto (August) rhymes with desgosto (sorrow).

In many Spanish speaking countries, the movie "Friday the 13th" was renamed to Tuesday the 13th ("Martes 13") Tuesday 13 is believed to be a day of bad luck, not Friday 13.

Hm, do you all believe in these? Weird.....
