Nominal age

China's customary age calculation method is based on the calendar year after birth, that is, even if he was born as 1 year, he will increase 1 year after every new year. Generally, it is calculated according to the lunar calendar, but also according to the Gregorian calendar. For example, people born at the end of 65438+February will be 1 year after birth and 1 year after the Gregorian calendar and/or the local Chinese New Year.

Zodiac age comparison table 202 1 calculation method of nominal age:

The nominal age is an important folk custom in China, which is based on the Spring Festival (Lunar New Year), while the one-year-old is based on my birthday. The specific conversion method is as follows: (1) Conversion from nominal age to full age: full age before my birthday in the solar calendar = nominal age-2; Birthdays 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 centenary watches.

The calculation method of nominal age is: one year old at birth and one year old after the Spring Festival every year (beginning of spring in ancient times). However, some people are two years older than their full age, and 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 their full year, and the second half is two years older (solar 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 bears in mind the hardships of ancient human reproduction and the great kindness of the mother who was pregnant in October.

If this popular view in China is correct, it is logical for China people to calculate the start date of pregnancy as the growth point of their birthdays and ages. At least, the virtual age should not mean from birth to New Year's Eve, that is, it should not be as short as one year, but should take birthday as the age growth point, which is also roughly logical.

In ancient China, the lunar calendar (actually a calendar, not a lunar calendar) was arranged according to the moon phase cycle. However, in combination with the year calculated with reference to the position of the sun, there would be leap months due to the adjustment time error. But the ancients did not celebrate their birthdays twice in the same year. In addition, the ancient calendar will be adjusted in terms of counting days due to special circumstances such as the change of dynasties and the accession of new emperors, so "emphasizing young days" is the characteristic of the imaginary age algorithm.
