For entertainment
This site provides a Chinese gender-chart lookup and calendar information for general interest and entertainment. It is not a medical service and does not predict a baby’s sex with scientifically established accuracy.
Do not rely on it for healthcare, reproductive or other consequential decisions. Direct pregnancy and medical questions to a qualified professional.
Calculation limits
We document the calendar convention, chart version and leap-month rule used here. Other charts may disagree. Due-date calculations estimate conception, and calendar data may contain limitations or errors.
The chart supports lunar ages 18 to 45. The date converter supports years 1900 to 2099. An unsupported result is not filled in or inferred.
Using the content
You may use the tool and print the chart for personal reference. Our original party-game printables are free for personal, noncommercial events. You may print copies for your guests; please link to the download page rather than selling, repackaging or redistributing the PDF files. Third-party software and chart data retain their licenses and attribution notices.
Availability and updates
The site may change as its implementation or sources are updated. We do not promise continuous availability or a particular outcome. Our privacy page explains the current data handling.
