What is the basis for the 24 solar terms?

In order to make it easier to remember, people have compiled the 24 solar terms: 24 solar terms song Spring rain shocks the spring valley sky, summer is full of mangs and summer heat is connected, autumn dew and autumn frost fall, winter snow and winter small and big cold. Twenty-four solar terms and seven words poem The earth revolves around the sun, and it is a year to complete a circle.

The year is divided into twelve months, and twenty-four festivals are closely connected. According to the Gregorian calendar, the two gases do not change every month. The first half of the year was.

Sixth, Ganyi, the second half of the year.

Eighth, Gan San. These are the festivals, and there is no more than a day or two. The twenty-four verses are in order, and the following mantras are memorized:

In January, the small cold is followed by the big cold, and in February, the spring rain is connected; The spring equinox is in March, and the rain in Qingming Valley is in April; Lixia and Xiaoman in May, and the summer solstice in June; July heat and small heat, the beginning of autumn and summer in August; The white dew in September is followed by the autumn equinox, and the cold dew and frost fall in October; The beginning of winter light snow in November, heavy snow winter solstice to welcome the new year. Seize the season to busy production, planting and harvesting in time to ensure a bumper year. With the spread of the Chinese calendar, the 24 solar terms have spread to many parts of the world.

The 24 solar terms are determined according to the position of the sun on the ecliptic, that is, the position of the sun in the earth's orbit around the sun, that is, every 15°.

In ancient China, the sundial was measured by Tugui, and the longest annual shadow was set as the "solstice" (also known as the day solstice, the long solstice, and the winter solstice), and the shortest day shadow was the "day short solstice" (also known as the short solstice, summer solstice). In spring and autumn, when the length of day and night is equal, it is designated as the "spring equinox" and "autumn equinox". In the Shang Dynasty, there were only four solar terms, but by the Zhou Dynasty it had developed to eight, and by the Qin and Han dynasties, the twenty-four solar terms had been fully established.

In 104 B.C., the "Taichu Calendar" formulated by Deng Ping officially set the 24 solar terms in the calendar, clarifying the astronomical position of the 24 solar terms.

The names of the 24 solar terms were first seen in the Huainanzi Tianwenxun, and the concepts of yin and yang, the four hours, the eight positions, the twelve degrees, and the twenty-four solar terms are also mentioned in the "On the Essence of the Six Schools" in the "Historical Records of Taishi Gongzi Self-Order". During the reign of Emperor Wu of the Han Dynasty, the solar terms were compiled into the "Taichu Calendar", and the month without Zhongqi was set as the leap month of the previous month.

Each of the 24 solar terms corresponds to a certain position reached by the Sun for every 15° movement on the ecliptic. The 24 solar terms are divided into 12 solar terms and 12 middle terms, one by one. The 24 solar terms reflect the annual apparent movement of the sun, so their dates are relatively fixed in the Gregorian calendar, the solar terms in the first half of the year are on the 6th, the middle solar terms are on the 21st, the solar terms in the second half of the year are on the 8th, and the middle solar terms are on the 23rd, and the two are the same as 1 2 days.

The naming of the 24 solar terms reflects three types: seasonal, phenological phenomena, and climate change. The reaction seasons are 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, also known as the eight; The phenological phenomena that reacted were stinging, Qingming, Xiaoman, and miscanthus; Reflecting climate change are rain, valley rain, small heat, big heat, heat, white dew, cold dew, frost, light snow, heavy snow, small cold, and big cold.

Among the 24 solar terms, there are both solar terms and traditional festivals, such as the Qingming Festival and the winter solstice. Qingming Festival, Qingming Festival is a traditional major spring festival, sweeping tombs to worship, remembering ancestors, is a fine tradition of the Chinese nation since ancient times; Winter solstice, winter solstice known as "winter solstice as big as the year" said, most of northern China to eat dumplings on this day, because dumplings have the meaning of "cold", so far the folk still spread the folk proverb "winter solstice does not serve dumpling bowls, freeze off the ears and no one cares".

Qingming Festival, also known as the Qingqing Festival, Xingqing Festival, March Festival, Ancestor Festival, etc., the festival period is at the turn of mid-spring and late spring. Qingming Festival is an ancient festival of the Chinese nation, which is not only a solemn festival of sweeping tombs and worshipping ancestors, but also a joyful festival for people to get close to nature, go out to play, and enjoy the fun of spring.

In this season of Qingming Festival, the vitality is vigorous, the yin qi is declining, all things "spit out the old and accept the new", and the earth presents the image of spring and Jingming, which is a good season for the suburbs to go on a youth tour and perform the tomb sacrifice.

The winter solstice is the 22nd solar term in China's 24 solar terms, in the folk, the winter solstice solar terms should also be held to congratulate the winter and worship the winter activities, such as the winter solstice festival in November of the lunar calendar, worship the family temple, the shrine, worship the parents and elders, and set up a family banquet to congratulate relatives. The custom of eating dumplings on the winter solstice is widely spread among the people.

1. Origin: The solar term is the product of the ancient agricultural civilization, which was originally formulated according to the movement of the stars, and the ancients guided agricultural production according to the direction of the Big Dipper in the night sky. During the period of Emperor Wu of the Western Han Dynasty, the "24 solar terms" were incorporated into the "Taichu Calendar" as a supplement to the calendar to guide agricultural affairs, and the solar terms were measured in the Yellow River Basin by the Gui Table Shadow Measurement Method.

2. Meaning: The solar term is a specific festival in the Ganzhi calendar that indicates the change of natural rhythm and establishes the "December Jian" (monthly order). The twenty-four solar terms are:

Beginning of spring, rain, stunning, vernal equinox, Qingming, valley rain, beginning of summer, small man, miscanthus seed, 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.

The value of the 24 solar terms

The 24 solar terms have the significance of time markers and seasonal transitions. The labeling and use of the 24 solar terms means that China retains its own characteristics and elements while keeping pace with the rhythm of the world.

Not only that, the names of the 24 solar terms themselves are associated with the flow of time and changes in climate and phenology, and 8 of them reflect seasonal changes (i.e., equinoxes and solstices and quadrangles); 5 reflect temperature changes (i.e., small heat, big heat, heat, small cold, and big cold).

Seven of them reflect the changes of precipitation (i.e., rain, valley rain, white dew, cold dew, frost, light snow, heavy snow), and four reflect the changes of phenology (i.e., sting, Qingming, Xiaoman, and miscanthus), so they have a distinct suggestive significance of seasonal transformation, which is a characteristic and advantage that the Gregorian calendar does not have.

The above content reference: Encyclopedia - the origin of the 24 solar terms.

The 24 solar terms refer to the 24 specific seasons in the Chinese lunar calendar that indicate the change of seasons, which are divided into 24 solar terms based on the earth's revolution around the sun. The 24 solar terms are the climate laws formulated by people in ancient times according to the changes in the position of the earth on the ecliptic (that is, the orbit of the earth around the sun), and each one corresponds to a certain position reached by the sun every 15° of movement on the ecliptic.

Among the 24 solar terms, Qingming and the winter solstice are both solar terms and festivals. Qingming Festival, also known as the Qingqing Festival, the Qingqing Festival, the March Festival, the Ancestor Festival, etc. , held at the turn of mid-spring and late spring.

The Qingming Festival, which originated from ancient ancestral beliefs and spring sacrificial customs, has both natural and humanistic connotations, which is not only a natural solar term, but also a traditional festival.

The winter solstice, also known as the winter festival, the sub-annual festival, and the long festival, has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional Chinese folk festival. In ancient times, there was the custom of "eight festivals" to worship gods and ancestors.

The winter solstice is regarded as a big festival in winter, and the folk have a saying that the winter solstice is as big as a year, so the ancients called it "sub-year" or "small year".

Extend your data. Twenty-four solar terms:

The 20th draft of the Spring Four Solar Terms refers to the specific festivals in the calendar that indicate the seasons, phenology, climate change, and the establishment of the "December Architecture". They are the beginning of spring, rain, awakening, vernal equinox, Qingming, valley rain, long summer, small man, miscanthus seed, touching the branches of the summer solstice, summer solstice, beginning of autumn, early Shu, white dew, autumn equinox, cold dew, first frost, beginning of winter, light snow, heavy snow, winter solstice, small cold, big cold.

The 24 solar terms carry profound spiritual and cultural connotations, such as respecting nature, conforming to the time of day, respecting ancestors, filial piety and respect for relatives, and good neighborliness and friends, which are one of the important parts of China's excellent traditional culture.

The 24 solar terms can reflect the rhythm and rhythm of nature more accurately, and reflect the harmonious relationship between man and nature. This point is of great practical significance to people today.

The 24 solar terms are not only a time system, but also a life tradition full of rich connotations, and an important part of people's lives.

Today, although the role of the 24 solar terms in guiding agricultural production and regulating the rhythm of people's time and life is decreasing and disappearing, no matter how the times change, the logic of "living a life" will never change. In fact, in the process of the birth, development and historical changes of the 24 solar terms, its connotation has been changing and developing in response to the development and change of the social situation in Luzhong.

Therefore, on the basis of continuing the tradition, we can further "recreate", that is, dilute its guiding role in agricultural production, emphasize its relationship with the people's social life, let it fully participate in the social life of the modern people, and give full play to the functions and values of the 24 solar terms in people's daily interactions, leisure and entertainment, diet and health, etc., so that the "days" can continue to be carried out with taste.

Solar term folklore. The 24 solar terms scientifically reveal the law of astronomical and meteorological changes, which skillfully combines astronomy, natural rhythm and folk customs, and derives a large number of related seasonal cultures, which have become an important part of the traditional culture of the Chinese nation. In order to more accurately describe the characteristics of the time series, the ancients divided the solar terms into four groups according to climate and phenology: "divided, solstice, open and closed".

"Equinox" is the spring equinox and the autumn equinox, which was called "two equinoxes" in ancient times; "Solstice" is the summer solstice and winter solstice, and was called "two solstice" in ancient times; "Qi" is the beginning of spring and summer, and "closed" is the beginning of autumn and winter. The beginning of spring, the beginning of summer, the beginning of autumn, and the beginning of winter are collectively called "four stands", which add up to a total of "eight sections".

Folks call it "four seasons and eight festivals" or "eight festivals of the year". In a long agrarian society, the 24 solar terms have played an important role in guiding agricultural activities and have rich cultural connotations.

The 24 solar terms are a traditional Chinese method of calculating time, which is based on the trajectory of the sun on the ecliptic and the laws of the earth's revolution. The implementation of the 24 solar terms can help people better understand the changes in the natural world, grasp the timing of agricultural production, adjust their daily routines, and maintain physical and mental health.

For example, the vernal equinox solar term is the first solar term of spring, indicating that the sun reaches 0 degrees of yellow longitude, day and night are equinoxed, and the time of day and night is equal. At this time, the temperature gradually rises and the plants begin to sprout and grow, which is the beginning of spring farming. Liang Dan and Lixia solar terms mean that the sun reaches 45 degrees of yellow longitude, which means that it has entered summer, the temperature is gradually rising, the plants are growing rapidly, and it is necessary to strengthen management such as watering and fertilization.

Therefore, the formulation and implementation of the 24 solar terms will help people better understand the laws of nature, grasp the timing of the rough machine, improve production efficiency, and promote social development. At the same time, it also helps people to maintain physical and mental health, adjust their life and rest, and adapt to changes in the natural environment.

There are several reasons for the formulation and implementation of the 24 solar terms:

1.Agricultural production: The 24 solar terms are an important guide for traditional agricultural production in China.

Each solar term is related to an important link in agricultural production, such as the spring equinox and autumn equinox are related to the sowing and harvesting of crops. By formulating and implementing the 24 solar terms, we can help farmers rationally arrange agricultural activities and improve agricultural production efficiency.

2.Meteorological observation: The 24 solar terms were also a way to observe and record meteorological phenomena in ancient China. By observing climate change and celestial phenomena for each solar term, it is possible to predict future weather trends and provide meteorological information for farmers and other industries.

3.Cultural inheritance: The 24 solar terms are an important part of traditional Chinese culture, representing the Chinese's observation and perception of self-decay. The formulation and implementation of the 24 solar terms will help inherit and promote traditional Chinese culture and enhance the cultural identity and pride of the people.

4.Lifestyle: The 24 solar terms also have a certain impact on people's lifestyles.

Each solar term has customs and festivals associated with it, such as the Spring Festival, Qingming Festival, Dragon Boat Festival, etc. These festivals and customs enrich people's lives, add to the festive atmosphere and social activities, and promote social harmony and stability.

To sum up, the formulation and implementation of the 24 solar terms are of great significance for agricultural production, meteorological observation, cultural inheritance and lifestyle.
