Dear Rabbi Enkin,
I remember when I was living out east that my Jewish friends would only sign papers, or make major business deals, on Tuesdays. They said that was the best day. I don't remember why. I think they called it Tov Tuesday (or something like that).
Thank you, Beth
It is only on Tuesday (the third day of creation - Genesis 1:9-13) that the expression of "G-d saw that it was good" ("Ki Tov") is mentioned twice. Because of this, Tuesday is seen by many as having auspicious properties. As such, many people prefer to get married or commence a major endeavour on this day.
That being said, Tuesday has no halachic advantage or significance within Jewish law over any other day. There is no reason to needlessly delay business deals, and the like, in order to seal them on a Tuesday.
