How to calculate the age of fortune-telling pregnancy

Is the age of Buddhism one year old or nominal?

This is a nominal age.

One of the Buddhist classics, Dabaoji Sutra (Volume 56), is "The Sutra for Buddhism to Tell a Family to Enter the Fetus".

It is about the process of life entering the mother's womb and its growth and change in the mother's body. According to the principle of fetal meridian, the progress of life begins with the birth of God. Then, in 10, the mother became pregnant (9 months and 7 days according to the western calendar), and after the new life came out of the mother, she was already one year old. However, because he or she has never really lived in the world, he or she is called a nominal age. Buddhism's termination of contract is a nominal age.
