COTTonLINE wishes all of our readers a lucky Friday, the 13th of September. If you want to learn more about this particular superstition, Wikipedia isn't a bad source.
It turns out that, depending on the culture you're in, Tuesday the 13th or Friday the 17th may be the dreaded day instead of today. In a culture like ours where the five day, M-F work week is relatively standard, it is hard to see how people who gleefully proclaim TGIF can find any Friday date an unlucky day.
On the other hand, the truly lucky (of which I was one) like their jobs and value Friday no more (or less) highly than any other day. When you like your job all seven days of the week are fine.
