Our Wedding Date... there was a lot of flip-flopping when we tried to decide when to have our wedding. The original date(s) were sometime in mid-July, but with potentially humid weather those dates got the ax. Moving it back to June, we shot for the middle, and picked June 14th. Everything fell into place... except the reception site we wanted! Rather than try to move to another week, we decided to just move it back a day, and are going to be married on Friday the 13th. I guess its a good thing that the only Superstition in my life is a little Stevie Wonder!
Superstitions aside, I'm glad we went with a Friday, and would recommend it if all/most of your guests can make it. That way you can have a day in between the wedding and leaving for the honeymoon to have a nice brunch with your family, open presents, or just sit around and relax. It can also make things more affordable, venues may be willing to negotiate their rates on Fridays. The Knot has a nice little article on dates to avoid that can also be helpful.
