Is it a boy or girl?

So I am at the age (as well as most of my friends) where starting a family becomes a real reality and, for some, top priority.  A year or two ago I came across something called a "Chinese Gender Prediction" calendar.  It predicts the gender of your baby based on the mother's age at conception and the month it was concieved.  At first I gave the chart about as much thought as I do daily horoscopes (as in none) but, over the years, I have noticed an unsettling fact:  It seems to be right!?

I have gone through m-a-n-y combinations of friends/relatives/coworkers/etc and, aside from the occasional set of twins, this graph has only been wrong once!  Those odds are a little too good, for me.  This calendar was at the front of my mind today because a couple of my friends just found out they are having a baby girl .. and yes .. that was the prediction I made several months ago based on this calender.

So all in all I find this graph to be both intriguing and creepy.  I am SURE it is wrong in some instances .. I just haven't come across them yet.  So, if you are reading this and are expecting but don't know what it is, check this out and see what it says.  I would love to know if it turns out to be true.  At least you can get a head start in picking names, right?
