The Chinese calendar is a lunisolar calendar that has been used in China for centuries. It is based on the cycles of the moon and the sun, and it is used to determine the dates of holidays, festivals, and other important events.
The Chinese calendar is also used to predict the gender of a baby. According to the Chinese calendar, the gender of a baby is determined by the year, month, and day of the mother’s last menstrual period. There are a number of different methods for calculating the gender of a baby using the Chinese calendar, but the most common method is the “four pillars” method.
