Why do people in China have the saying of nominal age and full age?

Because imaginary age is a unique method to calculate the age of China people, because before the introduction of the solar calendar, the years of China people have been calculated according to the lunar calendar. Farmers are the lunar calendar that old people often say, and the age of a year is calculated according to the method of this year's solar calendar. In other words, the imaginary number is the age of the lunar calendar algorithm, and one year old is the actual age of this person.

Generally speaking, a nominal age is one year older than one, that is to say, a person is one year old from birth, and one year later. For example, a child's actual age is 15, but his nominal age is 16. I may think that the previous child was more difficult to raise, so I will give him a year old after landing. According to the old saying in the countryside, such children are better to raise.

Because of the poor living conditions in ancient times, especially industrial and agricultural farmers lived a life of relying on the weather. So if the harvest is good, they will have to work hard for a year to eat. If the harvest is not good, they may go hungry. Therefore, in order to prevent children from suffering with adults, he is counted as one year old from the beginning of landing, hoping that God can give the children a bite to eat.

Why does China have a lunar calendar? This is because China people use 24 solar terms to divide the years. Twenty-four solar terms, including beginning of spring, Qingming, Mangzhong, Spring Equinox, Long Summer, Summer Solstice, beginning of autumn, Autumn Equinox, Winter Solstice, etc., are the ancient dating methods in China.

Because China is an ancient farming country, their calculation methods are all around farming, because such statistics are very helpful for them to grasp the climate change and which time period is more suitable for farming.

In addition to the 24 solar terms, China people also divide a year into 12 earthly branches, which belong to 12 genus and 10 heavenly stems, so the earthly branches add up to 12 years, while a Xunzi is 60 years, so a Xunzi includes five 650. 12 is a small cycle, and 60 years is a big cycle. This is what the old people often say, I ching uses 12 earthly branches and a Xunzi to calculate the fate of a person's life.
