At the same time, we know that 2020 is the year of the rat, 202 1 is the year of the ox, and 2022 is the year of the tiger.

The year of Gengzi, the year of Xin Chou and the year of Renyin belong to the special names of Ganzhi calendar, which are marked by Ganzhi year, Ganzhi month and Ganzhi day.

The concept of "year" was originally formed by the phenology of crop maturity. "Shuo Wen Jie Zi" said: "The year is ripe." If grain maturity refers to the period from cold to summer, that is the time when the earth goes around the sun. Modern times call it solar year, also called solar calendar.

The calendar with the moon as the unit is the lunar calendar, also called the lunar calendar.

The calendar with the solar year as the unit is the solar calendar, also called the solar calendar.

The ancient calendar in China was not a pure lunar calendar, but a combined calendar of yin and yang.

That's what Yao Dian meant when he said, "The leap month is fixed at four o'clock". However, it should be noted that Yao Dian said "year", not "year", which refers to the period from a certain solar term this year (such as winter solstice) to the same solar term next year, so there is a division of labor with "year", which refers to the period from the first day of the first month of this year to the first day of the first month of next year. Therefore, "Li Zhou Guan Chun Da Shi" said that "a year's plan lies in things" and a year's plan lies in time.

According to the calendar method of trunk calendar, trunk calendar year, trunk calendar month and trunk calendar day, the first day in silver moon, namely "beginning of spring", is the change time of the animal year, so from 1 in 2022 to 1 on February 3, 2022, it is still the Year of the Ox.

February 4, 2022 is the first day of the Year of the Tiger.

In the long-term production practice, the ancients gradually realized the laws of seasonal change and climate change, and divided a 365-year-old day into 24 solar terms, including beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. Each solar term accounts for 15.22 days. According to the speed of the sun's movement, some solar terms account for more than 14 days (from winter to around) and some solar terms account for more than 16 days (from around summer). Reflecting the changes of seasons, temperature, rainfall and phenology with 24 solar terms is a summary of the working people's experience in mastering farming season in ancient China and has made great contributions to the development of agricultural production.

The 24 solar terms are an important part of the ancient calendar in China.

The twenty-four solar terms represent twenty-four different positions of the earth in its orbit around the sun.

The 24 solar terms system has been gradually improved. The ancients mastered the equal division of these four most important solar terms long ago: "Yao Dian of Shangshu" said that spring is divided into days, autumn is divided into nights, and "Lv Chunqiu" said that day and night are divided into minutes, because these two days are equal in length; Yao Dian called the summer solstice sunny and the winter solstice short. Because the days are the longest in summer and the shortest in winter, Lu's Spring and Autumn Annals are called "long days" and "short days" respectively.
