Is 7 considered lucky? 7? as in the number between 6 and 8? Correct.     A lot of people are superstitious about numbers. I'm not aware for 7 or numbers in general, I do understand that "superstition" means things like irrational actions or religious beliefs. Oh yeah I'm not religious about superstitions and such but I do believe in some of them like clovers.
