1 The Chinese Conceiving Calendar

The Chinese Conceiving Calendar, also known as the Chinese Pregnancy Chart, Chinese Conception Calendar or Chinese Gender Selection Chart, is a tool used to determine the best time to conceive a baby boy and the best time to conceive a baby girl. It is also used to predict the gender of an unborn baby. The calendar is based on two variables--the mother's age at the time of conception and the month of the baby's conception.

2 Using a Chinese Conceiving Calendar

The Chinese Conceiving Calendar is hundreds of years old and is based on the Chinese lunar calendar. Therefore, the mother's age and month at time of conception need to be "translated" into her Chinese age and the Chinese lunar month in order for the chart to work accurately. There are links at the end of this article to help you with conversion.

After determining this information, find the correct age on the vertical column and the correct month on the horizontal row. Now find the place where the column and the row intersect. A "B" indicates that that would be a good month to conceive a boy. A "G" means that a girl is more likely to be conceived that month by a mother of the specified age.

3 History of the Chinese Conceiving Calendar

In Imperial China, the Chinese Conceiving Calendar was originally invented for and used exclusively by royalty to ensure an abundance of male heirs. The chart was revealed to and used by ordinary citizens only after the fall of imperialism. The original calendar is said to reside at the Institute of Science and Technology in Beijing.

4 Tips and Warnings

Common errors with the Chinese Conceiving Calendar include remembering to use the lunar age of the mother and the Chinese lunar month. Another common error is miscalculating the date of conception.

When using the Chinese Conceiving Calendar to select gender, it is best to choose days toward the middle of a gender period. Avoid the first ten or last ten days of a gender period; these are considered days of "unsteadiness." If possible, select a gender period that runs for more than one month. The longer the gender period, the more steady the period is and the more likely you are to get the gender you want.

Today, the Chinese Conceiving Calendar is used primarily as an amusing way to guess an unborn baby's gender. It should not be relied upon as a fail-proof method for selecting or predicting gender.
