89 years old, 2023 years old?

Age, a word in China, 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.

In ancient times, the most important life etiquette of the Han people was the ceremony of male crown and female ceremony. To put it bluntly, I changed my hairstyle. Before the Qing Dynasty, Han people, both men and women, had all their hair. Three months after the baby is born, you should choose the auspicious day of the zodiac and cut your hair once, leaving only two small pieces.

Calculation method:

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, the baby born at the end of 12, after birth 1 year, Gregorian calendar 1 or after the local Chinese New Year 1 year.

2, one-year-old age

Also known as full age, it refers to the number of anniversaries or birthdays from birth to counting. For example,1A census was conducted at 0: 00 July 1990, and1A baby born in February 1989, with a nominal age of 2 years. In fact, it's just over 6 months, and I haven't had a birthday yet, so one year should be less than 1 year, that is, 0 year.
