I have been lurking around here for some time and am now ready to post for my first time. So please be gentle with me.

I am not sure where this should go, but since it is not a great debate (I do not think) and since it is not really that pointless and is a question I have decided to post it here. If this is not the best forum Moderators please move it as necessary.

Here is the question, I have found a web page that predicts the gender of a baby with it says “99%” accuracy. It is supposed to be an old chinese lunar chart. In the couple of examples I have been able to obtain, it has predicted them.

The web site is as follows [http://www.babyzone.com/chinese.htm](http://www.babyzone.com/chinese.htm)

My question: Is it possible (any research) that a woman’s body works differently based on the lunar cycle or a man’s body does in terms of the Xs or Ys that make it to the eventual goal?

I guess the Chinese have enough of a sample to be able to create such a chart.

Any thoughts?

I’ve seen discussions of this chart on various baby forums. It doesn’t seem to be particularly accurate. I have two kids and it was right the first time and wrong the second time.

Correction–I missed the part about “lunar” age. It was wrong both times.

I tried it on my brother and myself. According to the chart, we should both be girls.

But let me assure you that we’re not. I can supply visual proof if necessary.

According to the chart, I should have been a boy and my brother should have been a girl.

I think there are a few glitches in the system…

No visual proof necessary Arnold.

It was right on my daughter, but wrong on myself and my sister.

I haven’t checked my wife.

But in our sample (those who have posted on this message) it does not seem to be 99% accurate Viper.

Try Sonagrams (sp) they are more likely to be right (unless your child is uncooperative).

p.s. Welcome to the board. Have fun. The locals are fairly nice, just don’t ask about -gry or parkways or any other “cutesy” questions.

You know, so far this thing is amazingly INaccurate.

I’m curious, though, are people remembering that a full-term pregnancy is actually 40 weeks from conception, not nine months?
