Does each of the 24 solar terms refer to a period of time

Not for a period of time. In fact, it refers to this moment, and roughly it can also refer to this day. For example, we can see that some calendars explicitly say:

Today 6:45 Beginning of Spring" instead of writing "Today 6:45 begins Beginning of Spring".

Is that right? This is not a random writing, it has a strict meaning.

refers to a period of time, so for example, February 4 is just the beginning of spring.

Every year in December, there are two solar terms per month, the front is the festival and the back is the air. The beginning of spring refers to the day of the beginning of spring, this day is the festival, and the rain is the air of the month.

On February 4th, this day begins to carry out spring.

The 24 solar terms refer to the 24 specific seasons in the Chinese lunar calendar that represent the changing seasons, and are based on changes in the Earth's position on the ecliptic (i.e., the Earth's orbit around the Sun), each corresponding to a certain position reached by the Earth for every 15° of movement on the ecliptic. The origin of the 24 solar terms.

Historically, most of China's major political, economic, cultural, and agricultural centers were concentrated in the Central Plains of the Yellow River Basin, and the 24 solar terms were established based on the climate and phenology of this area. As early as the Spring and Autumn Period of the Eastern Zhou Dynasty and the Warring States Period, there was a concept among the Chinese working people of the southern solstice and the northern solstice. Subsequently, according to the position of the sun and moon at the beginning of the month and the middle of the month, and natural phenomena such as weather and the growth of animals and plants, people used the relationship between them to divide the year into 24 equal parts.

And give each equal part a proper name, which is the twenty-four solar terms. In the "December Chronicle" of Lü's Spring and Autumn Period, which was written in the late Warring States period, there are eight solar terms such as the beginning of spring, the spring equinox, the beginning of summer, the summer solstice, the beginning of autumn, the autumn equinox, the beginning of winter, and the winter solstice, which are the most important of the 24 solar terms. The transition of the seasons is marked, and the four seasons of the year are clearly demarcated.

By the Qin and Han dynasties, the 24 solar terms had been fully established.

The 24 solar terms of the year originated in the Yellow River Basin, which is the crystallization of the long-term experience and wisdom of the ancient Chinese working people. As early as the Eastern Zhou Dynasty of the Spring and Autumn Warring States period, the Chinese had the concept of the southern solstice and the northern solstice, and set solar terms, such as mid-spring, mid-summer, mid-autumn and midwinter. The 24 solar terms are an auxiliary lunar calendar established in ancient China to guide agricultural production.

It is the crystallization of the long-term experience and wisdom of the working people of the Han nationality in ancient China. It was formed during the Spring and Autumn Period and the Warring States Period.

The lunar calendar is a "lunisolar calendar" that is based on the movement of the sun and moon. Therefore, it does not adequately reflect the cycle of the Sun. However, ancient China was also an agrarian society.

Agriculture requires a strict understanding of the movement of the sun, and agriculture is carried out exactly according to the sun. As a result, the "24 solar terms" were added to the calendar as a criterion for determining leap months, which respectively reflected the sun's cycle. The 24 solar terms can reflect seasonal changes, guide agricultural activities, and affect the clothing, food, housing and transportation of thousands of families.

The 24 solar terms are divided according to the position of the Sun in the ecliptic, which is the Earth's orbit around the Sun. As early as the Spring and Autumn Period of the Eastern Zhou Dynasty and the Warring States Period, the working people of the Han nationality had the concept of "Japan's north-south solstice".

The year is then divided into 24 equal parts based on the relationship between the sun and moon at the beginning and middle of the month, the weather, the growth of plants and animals, and other natural phenomena. And gave each equal share a proper name, that is, the twenty-four solar terms. The "December" of the Lu Spring and Autumn Period in the late Warring States period had eight solar terms, including spring and summer, spring equinox, early summer, summer solstice, early autumn, autumn equinox, early winter, and winter solstice.

These eight solar terms are the most important of the 24 solar terms. Mark the change of seasons and clearly divide the seasons of the year. By the time of the Qin and Han dynasties, the 24 solar terms had been fully established, and the names of the 24 solar terms in Huainanzi were exactly the same as in modern times.

In 104 BC, Deng Pingping's "Taichu Calendar" formally determined the 24 solar terms in the calendar and determined the astronomical positions of the 24 solar terms. In 104 B.C., Deng Pingping's "Taichu Calendar" formally determined the 24 solar terms in the calendar, determined the astronomical position of the 24 solar terms, divided the year into 24 levels, and gave each equal solar term a proper name. This is 24 solar terms, 2 solar terms per month.

China's 24 solar terms were originally formulated according to the rotation of the stars, and the current 24 solar terms were established more than 300 years ago according to the division of the sun's yellow and yang degrees.

This is based on traditional Chinese culture, according to the changes of the four seasons, according to the transformation of the sun and the moon.

The only one of the 24 solar terms that is both a season and a traditional festival is (Qingming).

Twenty-four solar terms: the beginning of spring, rain, stunning, vernal equinox, Qingming, Guyu, Lixia, Xiaoman, mangzhong, summer solstice, small heat, great heat, beginning of autumn, summer heat, white dew, autumn equinox, cold dew, frost, beginning of winter, light snow, heavy snow, winter solstice, small cold, big cold.

And to be thankful, life is born in the spring and autumn seasons.

The beginning of winter and the winter solstice are the two solar terms that are both solar terms and festivals among the 24 solar terms. The beginning of winter is one of the 24 solar terms of the lunar calendar, usually on November 7 or 8 every year, which is the beginning of winter in the solar calendar, which marks the official start of winter. In the lunar calendar, solar terms are defined as the moment when the sun reaches the moment of 225 degrees of ecliptic longitude.

Lidong is a traditional Chinese festival and is the 19th of the 24 solar terms in the lunar calendar. On the day of the beginning of winter, there is a custom of eating persimmons in southern China, while there is a traditional habit of "winter tonic" in the north. People will eat some nutritious foods to strengthen the body's resistance.

The winter solstice is the 22nd of the 24 solar terms in the lunar calendar, usually on December 21 or 22 every year, also known as the "Winter Festival" or "Ya Sui". The winter solstice is the shortest time of the year and the longest night, and it is also the first auspicious solar term of winter. In traditional Chinese culture, the winter solstice is an important festival, which has an important cultural connotation and symbolic significance in China.

In the north, for example, people eat foods such as dumplings and glutinous rice balls, which symbolize reunion and pray for peace. At the same time, there are also some places where there will be sacrificial ceremonies for the winter solstice festival, such as the "ancestor worship ceremony" in the south.

In short, the two solar terms of the beginning of winter and the winter solstice not only represent the change of seasons, but also have important cultural significance and traditional customs. They are important festivals in ancient Chinese culture, reflecting the Chinese people's awareness and love for natural landscapes, as well as emotional sustenance for family, family and country. <>
