The lunar calendar, which is based on cycles of the lunar phase, has been used in China as an agricultural time guide for thousands of years. The lunar calendar is also a very important element in the practice of Chinese fortune-telling. By telling fortune-telling practitioners your lunar year, lunar month, lunar day, and lunar hour of your birthday, they should able to tell your past, and they can also give you a detailed prediction of your future. Needless to say, the lunar calendar is very essential for the Dr.Jonas and the Chinese Gender Chart gender selection method.

Every year on the 15th day of the 8th lunar month, The Chinese celebrate this festival with lanterns and moon cakes. As the moon appears to be at its roundest in every 15th day of lunar month, so it must be a full moon day at the Mid-Autumn Festival.

Some scientists warn that it is best to avoid getting pregnant on full moon days because it has a greater chance of having a baby with a birth defect*. Why? On full moon days, the Moon, the Earth and the Sun are all in a line, so the tides are the greatest. As more than 2/3 of the human body is made up of liquid, the strong gravitational force will also cause the highest biological tide inside our body and brain, during the full moon period. Such internal body changes will result in depression, anxiety, and behavioral problems. You might notice that some people get surges of anger easily when the tide is high, and this is called Lunatics (Luna=Moon).

There is no conclusion of why biological tide can cause emotional changes, but it is most likely that human hormones can be affected by gravitational force. Imbalanced hormones could certainly result in emotional changes. Since either imbalanced hormones or emotions will affect the quality of sperms and eggs, it is recommended that don’t get pregnant during full moon days or the embryo may suffer from birth defect.
