The Chinese pregnancy calendar is an ancient method of predicting the sex of a baby, based on the Chinese lunar calendar. It is believed that the gender of a baby is determined by the mother’s age at the time of conception and the lunar month in which the baby is conceived.
The Chinese pregnancy calendar has been used for centuries in China and other Asian countries. It is still popular today, although there is no scientific evidence to support its accuracy. However, many people find it to be a fun and interesting way to predict the sex of their baby.
