traditional Chinese culture

Origin of solar terms: Twenty-four solar terms originated in the Yellow River Basin. As early as the Spring and Autumn Period, four solar terms were set, namely, mid-spring, mid-summer, mid-autumn and mid-winter. After continuous improvement and perfection, by the Qin and Han Dynasties, the 24 solar terms had been completely established. In BC 104, the taichu calendar written by Deng Ping officially set 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms.

Twenty-four solar terms: Twenty-four solar terms are the original cultural heritage of working people in China, which can reflect the changes of seasons, guide agricultural activities and affect the food, clothing, housing and transportation of thousands of families. Since 2000, the main political activity center in China has been concentrated in the Yellow River Basin, and the 24 solar terms have been established on the basis of the climate and phenology in this area. Due to the vast territory and changeable terrain of China, the 24 solar terms are only a reference for many regions. From the literal meaning of the twenty-four solar terms: beginning of spring, Changxia, beginning of autumn and beginning of winter-respectively represent the beginning of the four seasons. "Stand" means to start. The Gregorian calendar is generally around February 4th, May 5th, August 7th and165438+1October 7th every year. Solstice in summer and Solstice in winter-this means that summer and winter have arrived. "To" means to arrive. Summer solstice and winter solstice are generally on June 2 1 day and February 22 12 of the Gregorian calendar every year. Autumnal equinox, autumnal equinox-means that day and night are equal in length. "Divide" is equal share. These two solar terms are generally around March 20 and September 23 of the Gregorian calendar every year. Rain-indicates that the precipitation begins and the rainfall gradually increases. It rains around February 18 in Gregorian calendar every year. Sting-the sudden movement of spring thunder woke the hibernating animals in the soil. At this time, the temperature rose rapidly, and the spring thunder gradually sprouted. Every year around March 5 of the Gregorian calendar is a shock. Qingming-includes the meaning of sunny weather, fresh air, gradually warming climate and lush vegetation. The Gregorian calendar is Qingming around April 5 every year. Grain Rain —— The increase of rainfall is very beneficial to the growth of cereal crops. Grain Rain is around April 20th of the Gregorian calendar every year. Xiaoman-refers to the summer crops with full seeds, but not yet mature, just small and not yet full. Every year on May 2 1 day of the Gregorian calendar, it is full. Crops with awns, such as awn seed wheat, mature and summer sowing begins. Around June 5 every year, it is a mango. Hot in summer, hot in summer, hot in summer-hot in summer means hot. The heat is not the hottest time, but the heat is the hottest season, and the heat is the day when summer is coming to an end. They are around July 7, July 23 and August 23 of the Gregorian calendar every year. White dew-the temperature began to drop, the weather turned cold, and there was dew on the vegetation in the morning. The Millennium is around September 7 of the Gregorian calendar every year. Cold dew-the temperature drops, there is condensation in the air, and there is a chill gradually. This day is usually on June 8 10 every year. First frost-it's getting colder and colder, and it's frosting. The first frost usually occurs on the 23rd day of the Gregorian calendar 10 year 10. Light snow, heavy snow-it's starting to snow, with small and large indicating the degree of snowfall. Light snow falls on Gregorian calendar165438+1October 22nd, and heavy snow falls around 65438+February 7th. Slight cold, severe cold-the weather is getting colder and colder. Slight cold is not the coldest, but severe cold is the coldest time of the year. The Gregorian calendar 65438+1October 5th and 20th are mild and severe cold. The origin of the twenty-four solar terms originated in the Yellow River Basin. As early as the Spring and Autumn Period, four solar terms were set, namely, mid-spring, mid-summer, mid-autumn and mid-winter. After continuous improvement and perfection, by the Qin and Han Dynasties, the 24 solar terms had been completely established. In BC 104, the taichu calendar written by Deng Ping officially set 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms. The time when the sun runs along the longitude of the Yellow River from zero 15 degrees is called "a solar term". It runs 360 degrees every year, and * * * experiences 24 solar terms, twice a month. Among them, the first solar term of each month is "solar term", that is, beginning of spring, Jingzhe, Qingming, Changxia, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Hanlu, beginning of winter, Heavy Snow, Xiaohan, etc. 12 solar terms; The second solar term of each month is "Zhongqi", that is, there are 12 solar terms such as rain, vernal equinox, Grain Rain, Xiaoman, summer solstice, great heat, intense heat, autumnal equinox, first frost, light snow, winter solstice and great cold. "Solar term" and "neutral qi" appear alternately, each lasting 15 days. Now people have called "solar terms" and "neutral gas" solar terms. Twenty-four solar terms reflect the apparent movement of the sun in one year, so the dates of solar terms are basically fixed in the current Gregorian calendar, with the first half of the year being 6 days and 2 1, and the second half being 8 days and 23 days, with a difference of 1 ~ 2 days. In order to facilitate memory, people have arranged 24 solar terms: spring rain, song Jing, spring and clear valley days, summer full and summer hot, autumn cold and frost falling, and winter snow falling. The earth goes around the sun, and it takes a year to complete a circle. A year is divided into December, and the 24 solar terms are closely linked. According to the Gregorian calendar, these two gases will not change every month. The first half of the year is Saturday and Monday, and the second half is every eight days and every Wednesday. These are festivals, and the difference is only one or two days. In the twenty-fourth section, I remember the following formulas in my mind: a slight cold followed by a severe cold in January, and a rainy day in beginning of spring in February; The vernal equinox is in March and Qingming Grain Rain is in April. Long summer and full summer in May, full summer solstice in June; July is hot and slightly hot, and August is long summer, beginning of autumn; In September, the Millennium meets the autumnal equinox, and the first frost and cold dew are all in October; There is a light snow in 1 1 month in beginning of winter, and a heavy snow in winter solstice to welcome the New Year. Grasp the season and busy production, sow and harvest in time to ensure a bumper harvest. With the spread of China calendar, the 24 solar terms have spread to many parts of the world. The twenty-four solar terms are divided according to the position of the sun on the ecliptic (that is, the orbit of the earth around the sun). Depending on the sun starting from the vernal equinox (longitude zero, at this moment the sun shines vertically on the equator), every advance of 15 degrees is a solar term; After a week's operation, I returned to the vernal equinox, which is a tropical year with 360 degrees, so it is divided into 24 solar terms. The dates of solar terms are relatively fixed in the solar calendar. For example, beginning of spring in the solar calendar always falls between February 3rd and 5th. However, in the lunar calendar, the date of solar terms is not easy to determine. Take beginning of spring as an example. It can be the first day of the lunar calendar in the previous year, 65438+February 15, and the latest is the first month, 15. The current lunar calendar is neither a lunar calendar nor a solar calendar, but a combination of lunar and solar calendars. There is a leap month in the lunar calendar. If one year is counted from the first day of the first month to the New Year's Eve of the twelfth month, the number of days in the lunar calendar varies greatly (leap year is 13 months). In order to standardize the number of years, the first day of the Lunar New Year (heavenly stems and earthly branches) is not the first day of the first month, but beginning of spring. In other words, a year in the lunar calendar is the day before from beginning of spring in that year to beginning of spring in the following year. For example, 2008 is the fifth year of the lunar calendar. The first day of Wuzi began not on February 7, 2008 (the first day of the first lunar month), but on February 4, 2008 in Gregorian calendar. Twenty-four solar terms are the original cultural heritage of working people in China, which can reflect the changes of seasons, guide agricultural activities and affect the food, clothing, housing and transportation of thousands of households. Since 2000, the main political activity center in China has been concentrated in the Yellow River Basin, and the 24 solar terms have been established on the basis of the climate and phenology in this area.
