The nominal age is an important folk custom in our country, which is based on the Spring Festival (Lunar New Year) and the one-year-old is based on my birthday. The specific conversion method is as follows: (1) Conversion from nominal age to full age: before my birthday in the solar calendar, full age = nominal age-2; My birthday after the solar calendar, one year old = nominal age-1; Conversion from one year old to nominal age: before my birthday in the solar calendar, nominal age = one year old+2; After my birthday in the solar calendar, nominal age = one year old+1. The second type: nominal age = current year (lunar calendar)-year of birth (lunar calendar)+1. A complete collection of century-old watches.

The calculation method of nominal age is: one year after birth, one year after the Spring Festival (in ancient times, it is now beginning of spring). But some people are two years older than their full year of life. This algorithm is divided according to the first half and the second half of the year of birth. The imaginary year born in the first half of the year is only one year older than the full year, and the second half is two years older (solar calendar or lunar calendar).

There is a saying: "People in China regard pregnancy in October as one year old, which is also called nominal age. This year, I remember the hardships of ancient human reproduction and the great kindness of my mother who was pregnant in October. It also embodies the traditional virtue of China people to respect the old and love the young. If this popular view in China is correct, it is logical for China people to calculate the starting date of pregnancy as the growth point of birthday and age. At least, a virtual age should not mean from birth to New Year's Eve, that is to say, it should not be as short as one year, but should take birthday as the age growth point, which is also roughly logical.

However, combined with the year calculated with reference to the position of the sun, leap months appeared due to the adjustment time error.

In addition, the ancient calendar will be adjusted in terms of counting days due to the change of dynasties and the accession of new emperors, so "emphasizing young days" is the characteristic of the imaginary age algorithm.
