A Brief History of the Chinese Gender Prediction Calendar To be known as a patriarchal society, China was apt to favor the birth of males over girls because males were believed to carry forward family legacy.
As the pregnancy progresses, the accuracy of an ultrasound for predicting due dates decreases. Between 18 and 28 weeks of gestation, the margin of error increases to plus or minus two weeks. After 28 weeks, the ultrasound may be off by three weeks or more in predicting a due date. Thus, later in pregnancy, ultrasound measurements are more valuable for evaluating the baby's growth over time (compared with earlier measurements) than they are for predicting a due date.
