For me no 13 and the Tuesday is a day with bad luck , it'a day you can have many bad things bad (threehours).
But is it just when you think for ex : O my God today is Tuesday 13 is not good, .... you attract something negative and then all you go wrong in that day ...
I don't know why !!! but if that day happens , is all :)) :D , It is undoubtedly the most superstitious number...
