Chinese Gender Predictor

Chinese Gender Predictor (chinesegenderpredictor.app) is a free, transparent calculator for the traditional Chinese gender chart, a folk calendar that has been shared among families for generations as a fun pregnancy tradition.

You enter two Gregorian dates: the mother's birth date and the conception date. The tool converts them into the mother's lunar age and the lunar conception month, using lunar calendar data verified against Hong Kong Observatory tables for 1901 to 2100. It then locates the matching cell in the 336-cell chart covering ages 18 to 45. Unlike many quick widgets, it shows every conversion step, so you can see exactly how the result was reached and check it yourself.

The chart cells were checked against three published copies. The site also includes a full printable chart, a 2027 calendar view and guides that explain lunar age, leap months and common mistakes when reading the chart.

Everything runs in your browser. There are no accounts, no fees and no dates sent to a server. The site is clear that the chart is a cultural tradition for entertainment, not a medical prediction. It is available in English and Chinese. Website: https://chinesegenderpredictor.app/
