Gregorian calendar is a genus.

The zodiac is the zodiac, calculated according to the lunar calendar. For example, a person was born in Gregorian calendar 202 1 and 1. Although it is in Gregorian calendar 202 1, it is in December of the lunar year of the rat. As the Spring Festival has not yet passed, it is still the Year of the Rat. This man's zodiac is still a mouse, not a cow.

When calculating the age of China people, there are often imaginary years and real years. Full age refers to a person's actual age, and nominal age refers to adding one or two years to the full age. What is the reason?

In fact, this way of calculating age is related to the ancient calendar in China. The calendar commonly used in ancient China is the lunar calendar, which is also called the summer calendar, the lunar calendar or the lunar calendar, as opposed to the Gregorian calendar, which is commonly used all over the world today. In the long-term agricultural production, the ancients used to use the lunar calendar to calculate agricultural time, and gradually got used to using the lunar calendar to calculate many things. The calculation of nominal age is an example. In ancient times, although there was no uniform standard to calculate the nominal age, most people thought that a child should be recorded as one year old from birth, because October pregnancy was the embodiment of animism in the eyes of the ancients. In the future, every Lunar New Year (that is, the Spring Festival, not the Gregorian New Year) will increase by one year, so the nominal age is often greater than the whole year. If you were born in the twelfth lunar month (the twelfth lunar month), you will be two years old right after the Spring Festival, so the nominal age is two years older than the full one. So let's summarize the calculation method of nominal age: based on the time of calculating age, if the calculation time is from Lunar New Year to birthday, nominal age = one year old +2 (that is, two years old); If the calculation time is from birthday to Lunar New Year, nominal age = one year old+1 (that is, one year old). The calculation method of one year old is relatively simple, and it can be calculated according to the year, month and day of the Gregorian calendar. For example, we will keep a diary on August 8, 2009 and calculate the nominal age and one year old of a person born on June 8, 198 1. Because the Chinese New Year in 2009 has not passed, this person's nominal age should be 29 now, and his current one-year-old should be 28 (he will be 28 on June 8, 2009).
