While the chinesegendercalendar is based on ancient lunar methods, its accuracy is not guaranteed. The calculator works by taking the mother's lunar age and conception month to predict gender, which can be fun, fast, and culturally fascinating. However, the results are more of a tradition and entertainment rather than scientifically proven facts. Many people enjoy using the chinesegendercalendar as a lighthearted way to guess the baby's gender, but it may not be accurate for everyone.
