Traditional one-year algorithm

At this age, I still don't understand the relationship between one year old and nominal age. I think many post-80s will understand. Recently, young people (14-28-year-olds) are going to announce the May Fourth Youth Day holiday, so in order to avoid harming the interests of the elderly (you can take a half-day holiday, alas ...), it is necessary to clarify the relationship between the two so as not to omit the elderly from the list. Let's unveil the mystery of one-year-old and nominal age: the relationship between one-year-old and nominal age: nominal age is only related to Chinese New Year, and one-year-old is only related to birthday. At birth, it was 1 nominal age, and after the Spring Festival, it was one year after the birthday. Calculation method of nominal age = this year-year of birth+1 = this year-year of birth (birthday has passed) (. The tradition of one year old is calculated according to the lunar calendar. From New Year to birthday, the hypothetical age-one year old = 2 (that is, two years old) and from birthday to New Year-one year old = 1 (that is, one year old). The following is my personal summary. Any time can be counted: 1, (birthday hasn't arrived yet) one year old = your present nominal age -2 years old 2, (birthday has passed that year) one year old = your present nominal age-1 year old Example: Date of birth:1May 20, 983 Lunar calendar: April 8th Lunar calendar: 20.
