What does it mean to be over one year old?

Full age refers to real age, which is different from nominal age.

Actual age, also known as actual age, is the abbreviation of actual age. In real life, age is often used. Short for full-time age. Generally speaking, how many birthdays a person has had, his real age is only a few years old.

Because the test is calculated in months, the actual age also includes the months that people spend. For example, Xiaohua, born on 198 1 year 1 June 6, took an intelligence test on1April 988 10, with a real age of 8 years, 3 months and 4 days.

Calculation method of sufficient age

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 age

Also known as full age, it refers to the number of anniversaries or birthdays experienced from birth to calculation. 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 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.

Introduction:

Age refers to the length of time from birth to calculation, usually expressed in years. Age is a natural sign with biological basis. After a person is born, with the passage of the sun and the moon, his age increases, which is an irresistible natural law.

People are breeding their own times at the same time, and the times are always composed of individuals of different ages born in different times. In addition, various demographic phenomena, such as marriage, childbearing, schooling, employment, migration and death, are closely related to everyone's age. Therefore, it is of great significance to calculate the age correctly.
