There are nominal years and full years. What's the difference between them?

Bian Xiao first talked about the definition of one year old and nominal age.

1, one year old

One year old has two meanings: one is the meaning of one year old; In addition, it also refers to one full year of life. One year old is an internationally accepted age calculation method. It calculates the length of time that has passed since birth (based on the age of zero at birth), and can also calculate the mantissa, such as three years and two months, seven and a half years, etc. ).

2, nominal age

Nominal age, also known as gross age or nominal age, is a traditional way of counting age in China, and it is also very popular in other East Asian countries. It is used to calculate the sequence (ordinal number) of years experienced by people after birth, with one year at birth. Nominal age is a traditional way of counting age in China, and it is also very popular in other East Asian countries. I was one year old when I was born, because it was the first year after I was born, and it had nothing to do with the pregnancy that I had experienced for nearly a year. In China, in order to distinguish between two ways of calculating age, there are two names: nominal age and full age. In our country, in order to reduce disputes, the relevant laws calculate the age of the week for minors who commit crimes by delaying one day.

Bian Xiao will talk about the difference between a year old and a nominal age.

Calculate the difference

1, nominal age. China's customary age calculation method is based on the calendar year after birth, that is, even if he was born in 1 year, he will increase 1 year every New Year. Generally calculated according to the lunar calendar, but also calculated according to the Gregorian calendar. For example, a baby born at the end of 65438+February is 1 year after birth, or 1 year after the Gregorian calendar or the local Chinese New Year. In this way, the baby is only a few days old and is already 2 years old. This calculation method is unscientific.

2, one year old. Also known as full age, it refers to the number of anniversaries or birthdays from birth to counting. For example, the census was conducted at 0: 00 1 July 19901day. 1February, 989 15. The baby, whose nominal age is 2 years old, has just been over 6 months and has not yet had a birthday. According to one year, it should be less than 1 year, that is, 0 years old. One-year-old age is often 1 ~ 2 years younger than the nominal age, which can correctly reflect people's actual living age and is the most commonly used age calculation method in population statistics. ,,,, ③ The exact age. Refers to the days from the date of birth to the date of calculation. It reflects people's real life time more accurately than one-year-old age, but it is rarely used for demographic statistics because of its complicated statistical summary. In real life, except for babies under 1 year, especially newborns under 1 month, people usually don't calculate the exact age by day.
