plc - I found the info! Apparently the reason the chinese charts you find on the net are inaccurate is because you have to use your "lunar age", not just your normal age but the sites don't tell you that, or how to work it out.

I found a site that has a link to a page that you put in your birthday and the babies conception date, and then it works out your lunar age and predicts the gender. Google "thelaboroflove" and the the link is in the middle in the pregnancy section and is called "Chinese Gender Prediction Chart". Am I allowed to write that here? I hope so, don't want to get smacked...

I did it for me to see what the gender would be if we've been lucky enough to conceive, and apparently "It's a girl! (Chinese Age 30 at Lunar month 4)". Should I be upset that my lunar age makes me older?! Lol!!!
