Chinese Gender Predictor
Curious whether you might be having a boy or a girl? The Chinese Gender Prediction chart is one of the oldest and most popular folk methods for guessing your baby's gender. Based on the ancient Chinese lunar calendar, it uses the mother's age at conception and the month of conception to make a prediction.
For Entertainment Only
This tool is for fun and entertainment purposes only. The Chinese Gender Prediction chart has no scientific basis and is not a reliable method for determining your baby's sex. It has roughly a 50/50 chance of being correct — the same as flipping a coin! Only a medical ultrasound or genetic test can accurately determine your baby's sex. Please do not make any decisions based on this prediction.
Just for Fun!

About the Chinese Gender Chart
Legend has it that the Chinese Gender Prediction chart was discovered in a royal tomb over 700 years ago. The chart cross-references the mother's lunar age at the time of conception with the lunar month of conception to predict the baby's gender.
While many mums enjoy checking the chart for fun, there is no scientific evidence that it works any better than random chance. Studies have shown that the chart's accuracy is approximately 50% — exactly what you would expect from a guess.
If you would like to know your baby's sex with certainty, speak to your doctor about an anatomy scan (usually done between 18 and 22 weeks) or non-invasive prenatal testing (NIPT), which can be done from around 10 weeks.
