An interactive Chinese gender predictor chart can be found online at Chinesegenderchart.info. Charts are also available at the websites for Baby Center or The Bump. Each of these charts is interactive and also provides a static image of the Chinese gender calculator.
A Chinese gender calculator is used to predict the gender of an unborn child. The chart may also be used for gender selection. A woman can determine the best time to get pregnant to have an increased chance of having a particular gender of baby. To use the chart, the mother must know the lunar month in which she conceived as well as her lunar age at the time of conception. Lunar age is determined by the number of lunar cycles during which one has been alive. A lunar cycle is approximately 29 days.
Legends state that the Chinese gender chart is over 700 years old and was found in a royal tomb. The chart is said to be more than 90 percent accurate in predicting a baby's gender when used properly. There is no scientific proof the chart works, only documentation from reports of people who have used the chart. As such, the chart should be used for entertainment purposes only and not as an actual indicator of a baby's gender.
