The 700-Year-Old Chinese Birth Calendar

Archaeologists discovered this chart buried in a royal tomb near Beijing, where it had rested for over 700 years. It is now preserved at the Institute of Science in Beijing, reportedly used by the imperial family to plan the gender of their heirs.

The prediction works by cross-referencing the mother's age at conception with the month of conception. Thousands of parents worldwide have found it surprisingly accurate — but remember, this is cultural tradition, not medical science.

Frequently Asked Questions

How accurate is the Chinese Gender Predictor?

The Chinese Gender Predictor is based on an ancient lunar calendar and is a fun cultural tradition. Many parents report surprising accuracy, though there is no scientific evidence to support it as a medical prediction method. Statistically, any method has a 50% chance of being correct.

What age should I use — my actual age or Chinese lunar age?

Our tool uses your actual (Western) age at the time of conception. We have adapted the traditional chart to use Western ages for convenience and simplicity.

What is the month of conception?

The conception month is when the baby was conceived, not the due date or birth month. If planning a pregnancy, you can use a future month to see what the chart predicts.

Where does the Chinese Gender Prediction Chart come from?

The chart was reportedly discovered in a royal tomb near Beijing, estimated to be over 700 years old, dating to the Qing Dynasty. It is said to be preserved at the Institute of Science in Beijing.
