Chinese Gender Calendar Chart

According to legend, the Chinese developed a gender calendar thousands of years ago to predict a boy or a girl. The Chinese Gender Calendar is based on the lunar cycle, often correlated to a woman's menstrual cycle, and was buried in royal tombs for several millenia until discovered early during the Ming Dynasty (1368-1644).

To use the gender chart, you need to know the mom's age at the time of conception and the month the baby was conceived (Tip: Use our retro conception calculator to easily determine baby's conception month).
