Chinese Calendar is a free Android application developed by Vidamin Apps, categorized under Lifestyle/Entertainment. The program is compatible with Android version 6.0 and higher.

As the name suggests, the Chinese Pregnancy Calendar is based on a legend that predicts the gender of an unborn child. The application utilizes the Chinese Birth Chart to determine the baby's gender. According to the legend, the chart was buried in a royal tomb almost 900 years ago.

The application is easy to use, and all you need to do is enter the mother's age at the time of conception and the expected due date. The Chinese Calendar will then predict the gender of the baby. However, it is important to note that the application is based on a legend and should not be relied upon as a scientific method to determine the baby's gender.

Overall, the Chinese Calendar is a fun and interesting application for parents-to-be who want to predict the gender of their unborn child based on an ancient legend.
