The 20 solar terms are the crystallization of the wisdom of the working people of our country, and w

Not twenty solar terms, but twenty-four solar terms.

They are: 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.

The 24 solar terms are divided according to the position of the Sun on the ecliptic, which is the Earth's orbit around the Sun. The sun is regarded as departing from the vernal equinox (zero degrees of ecliptic longitude, at which point the sun is perpendicular to the equator), and every 15 degrees is a solar term; It runs for a week and returns to the vernal equinox, which is a return year, which is 360 degrees, so it is divided into 24 solar terms. The date of the solar term is relatively fixed in the solar calendar, such as the beginning of spring is always between February 3 and 5 in the solar calendar.

However, in the lunar calendar, the date of the solar term is not easy to determine, and taking the beginning of spring as an example, it can be as early as December 15 of the previous year, and as late as the 15th day of the first lunar month. The current lunar calendar is neither a lunar nor a solar calendar, but a lunisolar calendar that combines the lunar calendar with the solar calendar. There are leap months in the lunar calendar, and if one year is counted from the first day of the first lunar month to the Chinese New Year's Eve, the number of days in each year of the lunar calendar varies greatly (13 months in leap years).

In order to regulate the number of days in the year, the first day of each year of the lunar calendar (sexagenary branch) is not the first day of the first month, but the beginning of spring. That is, the year of the lunar calendar is from the beginning of spring of the current year to the day before the beginning of spring of the following year.

These solar terms are the laws that farmers must refer to when sowing seeds and carrying out farm work, and they have a great effect on the agricultural season.

It was most helpful to the peasants because there was a large part of the elderly who were illiterate and who only memorized proverbs, but these proverbs came from the twenty solar terms. He has brought wealth to the peasant uncles, I hope you will be satisfied!!

The 24 solar terms are a glorious culture created by the working people of our country, and its role in real life is as follows:

1. Guide people's labor and production, for example, start planting rice during the rainy season, start harvesting grains during the summer solstice, and pick peanuts after the cold dew. Accurately grasping the 24 solar terms can help people who are blind to better arrange production, improve efficiency, and ultimately obtain a better harvest.

2. To guide people's healthy life, medicine believes that climate is closely related to people's physical health, and people should pay attention to their diet and daily life in different solar terms to maintain the balance and health of the body.

3. Enriching people's cultural life, each solar term has unique customs and imitation connotations, such as boiling glutinous rice balls on the winter solstice, eating Laba porridge, and sweeping tombs during the Qingming Festival. These customs and festivals not only add to the joy of life, but also promote communication and interaction between people.

4. Improve people's awareness of environmental protection, there is an inseparable relationship between each solar term and natural phenomena, such as the temperature rises when the sting is stung, and it is necessary to pay attention to fire prevention and ventilation; The temperature rises after the beginning of summer, so it is necessary to pay attention to heatstroke prevention and cooling. Correctly grasping the meaning of the 24 solar terms will help people better protect and care for the natural environment in their lives.

5. It embodies the value of historical and cultural inheritance and grinding the spirit of the gods, and the 24 solar terms are an important part of Chinese traditional culture, which carries the wisdom and experience of the people for thousands of years, and represents the inherent spiritual and cultural characteristics of the Chinese nation. With a correct understanding of the meaning and function of the 24 solar terms, Panchai can help people better inherit and carry forward the excellent cultural traditions of the Chinese nation.

The stars are moving their fingers wide

In the pre-Qin period, some places in China determined the solar terms according to the movement of the stars, and the seven stars of the Big Dipper rotated in cycles, which was closely related to the twenty-four solar terms. Polaris is located at the northern end of the Earth's axis, on a five-fold extension of the line between Sky Swirl and Celestial Pivot in the Big Dipper.

Due to the rotation of the earth, and the North Star is exactly on the axis of the celestial sphere's rotation, it is relatively immobile, and the Big Dipper on the edge of the axis looks as if it revolves around the North Star, which produces the "Dou Rotation Star Shift".

The alternation of seasons is closely related to the "yellow-red intersection", which is the fundamental reason for the change of the four seasons and the distinction of the five zones on the earth, which affects the natural geographical phenomena closely related to it. The twenty-four solar terms are associated with the time of the stem branch and the eight trigrams, and they belong to the same system.

The "24 solar terms" and "December Jian" are the basic contents of the Ganzhi calendar, and the 24 solar terms are the specific seasons in the Ganzhi calendar that indicate the changes in the natural rhythm and establish the "December Jian" (monthly order). Since the twenty-four solar terms are determined by the rotation of the handle of the Big Dipper, this calendar is also called the "star calendar".

The role of the 24 solar terms in real life

The 24 solar terms are of great help to modern agriculture, and under the promotion of meteorology, many areas combine the 24 solar terms with agricultural meteorological data, and compile the agricultural calendar and agricultural activity table, so that the ancient experience and modern science and technology can be combined, cross-reference, supplement the forward, and play a role in modern agricultural production. The combination of these documents is based on the 24 solar terms.

Among them, the seasons of the 24 solar terms represent the changes of cold and summer (four seasons): 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; Symbolizes temperature changes: small heat, big heat, heat, small cold, big cold; Reflects precipitation:

rain, valley rain, white dew, cold dew, frost, light snow, heavy snow; Reflect phenological phenomena or agricultural activities: stinging, Qingming, Xiaoman, and miscanthus species.

The 24 solar terms are a glorious culture created by the working people of our country, which reflects the changes of the seasons and is used to guide agricultural activities and affect the clothing, food, housing and transportation of thousands of households.

The origin of the 24 solar terms

The "24 solar terms" is the product of the ancient agricultural civilization, which is a knowledge system formed by the ancient ancestors who conformed to the agricultural time, observed the movement of celestial bodies, and recognized the changes of season, climate, phenology, and difference in the year of the year. The twenty-four solar terms were originally formulated according to the rotation of the stars, the seven stars of the Big Dipper rotate in a cycle, and the handle rotates clockwise for a cycle, which is called a "year".

The current "24 solar terms" are formulated according to the position of the sun on the return ecliptic, that is, the annual trajectory of the sun is divided into 24 equal parts, every 15 degrees is 1 equal part, and every 1 equal part is a solar term, which begins at the beginning of spring and ends with the great cold.

Through historical development, the lunar calendar absorbed the solar terms components of the Ganzhi calendar as a supplement to the calendar, and adjusted it to conform to the return year through the "intercalation method" to form a lunisolar calendar, and the "24 solar terms" became an important part of the lunar calendar. In the international meteorological community, the 24 solar terms are known as "China's fifth greatest invention".

The 24 solar terms are a unique calendar created by summarizing the relationship between agricultural production and the sun and meteorology in long-term life practice.

The perfection of the 24 solar terms is the result of summing up the lessons of failure and successful experience on the basis of countless failures and successes of our predecessors. As early as the Spring and Autumn Period and the Warring States Period, China was able to use Tugui to measure the length of the sun's shadow at noon to determine the four solar terms of winter solstice, summer solstice, spring equinox, and autumn equinox. At noon, the shortest day of the year is the summer solstice, the longest day is the winter solstice, and the moderate shadow length is the spring or autumn equinox.

In ancient times, with the widespread use of farming tools, the area of cultivated land continued to expand, and agricultural activities became more and more sophisticated, and our ancestors' need to arrange agricultural activities according to the time of day also became more and more urgent. To this end, they combined the content of the 12 months of the year, which was determined by observing the phases of the moon, and gradually perfected the 24 solar terms. The 24 solar terms are unique to our country and an important discovery in the history of world astronomy.

To this day, it continues to guide agricultural production.

The 24 solar terms are summed up by the working people in their long-term production practice activities.

The 24 solar terms can reflect the changes of the seasons, guide agricultural activities, and affect the clothing, food, housing and transportation of thousands of households. In April 2014, the Ministry of Culture of China officially launched the application for the inclusion of the 24 solar terms in the UNESCO List of the Intangible Cultural Heritage of Humanity based on the position of the sun on the ecliptic (i.e., the orbit of the earth's filial piety ball around the sun).

Historical origins. The 24 solar terms refer to the 24 seasons and climate, and are a supplementary calendar established in ancient China to guide agricultural affairs.

The traditional East Asian summer calendar (lunar calendar) is a "lunisolar calendar" based on the movement of the day and the month: the part of the month is determined based on the synodic month, and the year is determined based on the return year (solar year). The Yang calendar is about one day after each return year, and the 24 solar terms are divided accordingly.

Since the main political, economic, cultural, and agricultural centers of China were mostly concentrated in the Yellow River Basin[1] Central Plains, 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 of the southern solstice and the northern solstice of the day among the working people of the Han nationality. 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 the "Spring and Autumn Period of the Lu Family", which was written in the late Warring States period, there are eight solar terms names, 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. These eight solar terms 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 book Huainanzi has the exact same name of the 24 solar terms as in modern times.

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.

In ancient times, the solar term was called "qi", and there were two qi per month: the former qi was called "solar term", and the latter qi was called "middle qi". The distribution of the 24 solar terms by month is shown in the table below, which is closely related to the arrangement of the leap month of the lunar calendar.

In the lunar calendar, the beginning of spring is the first of the 24 solar terms.

The names of the 24 solar terms are named after the places referred to by Dougang and combined with the natural climate and landscape of the time. The so-called Dougang is that the three stars of the Big Dipper, Kui, Heng and Dipper follow the movement of celestial bodies, and the Dougang points to different directions and positions, and the position it refers to is the month it represents. For example, the first month is Yin, the dipper refers to Yin at dusk, the middle of the night Heng refers to Yin, and the day Kui refers to Yin; February is the Mao, the dipper at dusk, the midnight Heng finger, the daytime Kui, and so on.

As early as the Spring and Autumn Period of the Eastern Zhou Dynasty and the Warring States Period, our people.

Among the people, there is a general idea that the south of the day and the north of the day will come.

Read. Then people according to the beginning of the month, the middle of the month.

The position of the sun and the moon and the weather, as well as the life of animals and plants.

long and other natural phenomena, using the relationship between them.

Divide the year into twenty-four equal parts. Combine.

And give each equal part a proper name, this.

It's the 24 solar terms. It was completed in the late Warring States period.

The book "Lü's Spring and Autumn Early Tong" "December 20.

The four solar terms and the zodiac signs.

In the "Ji", there is the beginning of spring, the spring equinox, and the beginning.

Summer, summer solstice, beginning of autumn, autumn equinox, beginning of winter,

The names of the eight solar terms such as the winter solstice. These eight verses.

Transformation, clearly delineating the four seasons of the year.

Lessons learned from the combination of farming and climate change!

The 24 solar terms of the lunar calendar are closely related to China's agricultural production. Chinese peasants were engaged in productive labor according to the solar terms, and they composed 24 solar terms songs to describe and record the situation of each solar term. Because the climate of China's north, south, east and west is very different, the 24 solar terms are not the same in various places.

Now I transcribe a song of the twenty-four solar terms that circulates in the Northeast:

The spring sun turns, the rain is along the river, the crows are stinging, the spring equinox is dry, the Qingming is busy planting wheat, and the valley rain is planting the fields.

Lixia goose feathers live, small birds come to the whole, mango seeds open shovels, summer solstice is not cotton, the summer heat is not hot, the heat is in the Futian.

The beginning of autumn is busy playing indigo, the summer is moving, the white dew is busy cutting the ground, the autumn equinox has no fields, the cold dew is not cold, and the frost has changed the sky.

The Lidong River is sealed, the Xiaoxue River is sealed, the heavy snow is handed over to the winter moon, the winter solstice is placed to sacrifice the day, the small cold is busy with compradors, and the big cold is the New Year.

This kind of proverb and ballad from the folk, although there are differences in one way or another, all exude a rustic earthy fragrance, allowing us to breathe a refreshing breath of Chinese folk culture.

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, the winter solstice, the stunning, Qingming, Xiaoman, the mang, the rain, the valley rain, the small heat, the great heat, the heat, the white dew, the cold dew, the frost, the light snow, the heavy snow, the small cold, the big cold.

The solar calendar is referred to as the solar calendar. The Earth's orbit around the Sun takes place in one year, 365 days in a year (365 days in a normal year and 366 days in a leap year), divided into 12 months. Due to the different positions of sunlight on the earth, the cold and warm temperatures are different, so there are four seasons: spring, summer, autumn, and winter.

Sunset and sunrise, wind, thunder, rain and fog.

In the long-term labor practice, through careful observation of nature, the ancestors summed up a set of laws of nature's operation - that is, a season can be subdivided into six solar terms, and four seasons are twenty-four solar terms.

Among the 24 solar terms, the seasons are reflected in 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; The phenological phenomena are stinging, Qingming, Xiaoman, and miscanthus; Reflecting climate change are rain, valley rain, small heat, big heat, summer heat, white dew, cold dew, frost, light snow, heavy snow, small cold, and big cold.

The beginning of spring, the beginning of summer, the beginning of autumn, the beginning of winter: it is the method of dividing the four seasons by the ancients. It means the beginning of spring, summer, autumn, and winter.

The date of the beginning of spring is around February 4 of the Gregorian calendar every year; The beginning of summer is around May 6 of the Gregorian calendar every year; The beginning of autumn is around August 8 of the Gregorian calendar every year; The beginning of winter is around November 7 of the Gregorian calendar every year.

Spring equinox, autumn equinox: indicates the equinox of day and night. The length of day and night is equal on these two days, and at the same time, the spring and autumn equinoxes divide spring and autumn into two parts. The spring equinox is around March 21 of the Gregorian calendar every year; The autumn equinox is around September 23 of the Gregorian calendar every year.

Summer solstice, winter solstice: refers to the arrival of hot summer and cold winter. And because the summer solstice has the longest days and the winter solstice has the shortest days, the ancients called them the day length solstice and the day short solstice respectively.

The summer solstice is around June 22 of the Gregorian calendar every year; The winter solstice is around December 22 of the Gregorian calendar every year.
