A Chinese gender prediction chart or calendar, often accompanied by an online calculator tool, uses the lunar age of the mother at conception and the lunar month of conception to predict the sex of a baby. For the year 2025, such resources would be tailored to the corresponding lunar calendar. These tools commonly present a grid or chart where the user inputs the relevant information to obtain a prediction. For instance, a user might enter their lunar age and the lunar month of conception to find the predicted gender in the corresponding cell of the chart.
While scientifically unsubstantiated, these charts and calculators hold cultural significance for many and provide a form of entertainment during pregnancy. Their historical roots lie in traditional Chinese practices, and they continue to be a topic of interest, particularly in online communities. It’s important to remember that these methods are not medically reliable for determining fetal sex and should not be used in place of scientific methods like ultrasound.
