About the Chinese Pregnancy Calendar
The Chinese Pregnancy Calendar (also known as the Chinese Gender Chart or Chinese Birth Chart) is a centuries-old method said to predict the sex of an unborn child based on the mother’s lunar age at conception and the lunar month of conception. According to legend, the original chart was buried in a tomb near Beijing over 700 years ago and is now kept in the Institute of Science in Beijing.
The chart uses the Chinese lunar calendar, which differs from the Western Gregorian calendar. Converting a Gregorian date to its lunar equivalent and adjusting the mother’s age to “lunar age” (typically +1 year) are required for accurate use. Our calculator handles these conversions automatically.

How to Use This Calculator Correctly
If you only know your expected due date, this tool first estimates your likely conception period, then converts your age and month into the lunar calendar used by the traditional chart. Because conception may happen a few days before or after the estimated date, your prediction can sometimes change if you try nearby conception dates. That is normal and reflects date uncertainty, not a problem with the calculator.
A practical way to use this page is to treat it as a fun cultural add-on while relying on medical methods for real planning. For example, families often use the Chinese chart for baby-shower games, keepsakes, and naming inspiration, while using ultrasound and prenatal care for health decisions.
