Is the international standard age calculation method based on one year old or imaginary age? Is imaginary age China's algorithm?

According to international practice, age is calculated by one year old, and the legal age is also calculated by one year old, but China people are used to calculating age by imaginary age.

China people's idle years are indeed scientific, after all, the birth of life itself is real! Before birth, when you are in your mother's belly, it should also be counted as the beginning of life!

However, the term "one year old" is more in line with the development of society. After all, only when you are born on the earth can you really breathe the natural air, truly become a human form and truly have human consciousness. Only when you have ideology in your mind can you feel real feelings, and you are a real person, so the saying of one year old is actually scientifically based.

Only nominal age pays more attention to the basis of biological science, while one year old is based on the formation of ideology!

From the perspective of the development of human society, taking one year as the legal age is more in line with the development direction of human society!
