Chinese gender predictor

A fun way to predict the gender of your baby

The Chinese Gender Calendar is considered one of the oldest methods for predicting the gender of an unborn baby. It is also one of the simplest, where the only necessary information is the mother's age at conception and the month of conception.

The Chinese Gender Calendar can be used in two ways. If you will use it for predicting the sex of an unborn child, simply enter your age at conception and the month of conception. If you will use it for planning your baby's gender, then find a suitable period for conception based on your age. In order to increase your chances, find a period when the gender remains steady for at least two months. See chart below.

When using the calendar to plan your baby's gender, to maximize the chance for correct prediction you should avoid conception during the first or last ten days of a gender period (period for conceiving a certain gender according to the calendar). Refer to chart below. The reason is that there are unknown, but apparently gradual changes taking place between two successive gender periods. During these changes the selection of gender happens more or less by chance.

How accurate is it? It is believed to be approximately 75% accurate (3 out 4 chance it will be correct).

Mother's Age At Conception:
Be sure to select the age you were when conception occured (this will likely be the day you ovulated).

Month of Conception:
Select the month when conception occured. This will likely be the day you ovulated. If you do not know your exact ovulation date, you can use the "average" and add 14 days to the first day of your last menstrual period. Keep in mind if you are estimating the prediction will not be as accurate.

 

 

Note: A common idea is that the Chinese Gender Calendar should be based on lunar cycles, as per the agricultural calendar (yin-yang-li). But since the Chinese Gender Calendar has its roots in astrology, which is based on the sun's movement around the zodiac, perhaps it makes more sense to use solar calendar dates. In fact, the research on this site shows that the highest accuracy is achieved when western dates (in accordance with the Gregorian calendar) are applied. In other words you don't need to convert birth dates and conception dates into other calendar systems.
