Chinese Gender Predictor: Complete Guide to the Chinese Gender Chart

The Chinese gender predictor is one of the most popular and widely searched baby gender prediction tools in the world. Expecting parents often use it for fun to guess whether they are having a baby boy or girl. Based on the ancient Chinese gender chart, this method claims to predict a baby’s gender using the mother’s age at conception and the month of conception.

Despite having no scientific backing, the Chinese gender predictor continues to attract millions of searches every year due to its simplicity, cultural history, and entertainment value.

What Is the Chinese Gender Predictor?

It is a traditional method that uses a Chinese gender chart to estimate a baby’s gender. The chart cross-references:

• Mother’s age at the time of conception
• Month in which conception occurred

The result predicts either a boy or a girl.

Today, this predictor is commonly available online as a calculator where users input dates instead of manually checking the chart.

History of the Chinese Gender Calendar

The Chinese Gender Calendar, also known as the Chinese Gender Chart, is an ancient method believed to predict a baby’s gender before birth. According to legend, this chart was discovered more than 700 years ago during the Qing Dynasty and was originally kept in the royal palace of China.

Historical stories claim that the calendar was buried in a royal tomb and later rediscovered, after which it was preserved and passed down through generations. The chart was reportedly used by imperial families and nobility to plan the gender of heirs, especially male successors, which were culturally preferred in ancient China.

The traditional Chinese Gender Calendar is based on two main factors:

• The mother’s lunar age at conception
• The lunar month of conception

Ancient Chinese astrologers believed these elements were connected to the Yin and Yang balance, the Five Elements (Wood, Fire, Earth, Metal, Water), and the Chinese lunar calendar, all of which play a major role in traditional Chinese philosophy and medicine.

Although many versions of the chart exist today, the original chart was never scientifically documented, which explains why different variations appear across websites and cultures.

How Does the Chinese Gender Predictor Work?

The predictor works on a simple grid system:

• Vertical axis: Mother’s age (usually 18–45 years)
• Horizontal axis: Month of conception (January–December)

Each intersection on the chart corresponds to either B (Boy) or G (Girl).

Modern calculators automatically:

• Calculate the mother’s completed age at conception
• Extract the month of conception
• Match the values against the Chinese gender chart

Basis and Theory Behind the Predictor

The Chinese gender predictor has no scientific basis. It does not consider genetics, chromosomes, or biological processes involved in sex determination.

Possible explanations for its popularity include:

• Cultural traditions
• Coincidental accuracy
• Confirmation bias
• Entertainment value

Scientifically, a baby’s gender is determined solely by whether an X or Y chromosome fertilizes the egg.

Accuracy and Precision of the Chinese Gender Predictor

Many websites claim that the Chinese gender predictor has an accuracy rate of 70–90%, but medical research does not support these claims.

Key points about accuracy:

• No clinical studies validate the chart
• Accuracy is comparable to random guessing (50%)
• Perceived success is often due to chance

Therefore, the this predictor should be used for fun only, not for medical or planning purposes.
