A reliable way to determine a baby’s gender is through medical procedures, such as ultrasound and cell-free DNA screening (NIPT). However, these tests often serve medical purposes rather than solely for gender identification (14). Furthermore, in some countries, fetal gender determination is forbidden legally, emphasizing the need for these tests to be performed under medical supervision and guidance only. The Chinese gender prediction chart and calendar is a traditional method used during pregnancy to determine a baby’s gender; it is based on the mother’s age and conception date. This engrossing tool originates from ancient Chinese culture and has gained popularity due to its ease of usage and purported accuracy. Although its historical associations and scientific validity are debatable, it is a popular non-scientific method to determine the baby's gender for parents with a casual curiosity about their baby being a girl or boy.
