If you ask your parents or grandparents, they will probably they will probably tell you that there was a time when expectant parents had to wait for the big day when baby made her (or his) grand entrance to find out the gender of their new baby. These days, most of us find out our baby’s gender during ultrasounds in the second trimester. As imaging improves, gender predictions are quite accurate.
But who says you need to wait until the second trimester to accurately predict whether you should be shopping for pink wallpaper or blue paint? Not the Chinese. The Chinese have been using gender prediction methods for thousands of years. Some claim they have over 90% accuracy.
The primary method used for early gender prediction is the Chinese gender prediction calendar. The version most often used was discovered in a royal tomb in the 1300s. The calendar is believed to have been developed by ancient Chinese scientists. There is some disagreement regarding how long the gender prediction calendar has been in use. Many suggest that the Chinese have been using gender prediction calendars for 7,000 years or more. Others suggest that the practice is somewhat more recent. In any case, Chinese have used the calendar for no less than 700 years.
When Chinese emigrated to the West, they brought the gender prediction calendar with them. While many Western people view it with suspicion, or see it as being entertaining, many others have come to embrace gender prediction calendars, along with other Eastern health care practices.
How It Works
To use a Chinese gender prediction calendar, you need to know the age of the mother in years at the time of conception and the lunar month at the time of conception. With these two pieces of information, you consult the gender prediction calendar. Proponents claim that you can predict the gender of your baby by cross referencing the age of the mother and the month at the time of conception.
Historically, the Chinese people have always preferred to have male offspring. Culturally, this was considered more prestigious. Historically, it was also more practical in a largely agrarian society.
Because many Chinese couples preferred to have boys, many would use the Chinese gender prediction calendar pro-actively. Essentially, they would consult the calendar to see when their best chances of conceiving a girl were. By saving sexual intercourse for those times, they believed that they would improve their chances of bearing sons. Presumably, the same method could be used if someone wanted to conceive a daughter.
