What is the solstice of winter every year?

Question 1: What does the winter solstice mean? But when is the solstice in winter? It is one of the twenty-four solar terms in China lunar calendar. Winter is coming, and the weather is very cold. Generally, it is around 2 1 in late December of the solar calendar.

Question 2: When is the solstice festival in the winter of the lunar calendar? In 2002, the winter solstice was on the 9th day of the lunar calendar 1 1 month/kloc-0, and the solar calendar was 65438+February 22nd.

Winter solstice, also known as "one-day birth", is an important solar term in the China lunar calendar and a traditional festival of the Chinese nation. The solstice in winter is commonly known as "number nine, winter festival", "long festival" and "sub-year". As early as more than 2,500 years ago in the Spring and Autumn Period, China had observed the sun with earth gauges and determined the winter solstice, which was the earliest of the 24 solar terms, and the time was between June 65438+February 2 1 ~23 in the Gregorian calendar every year.

The solstice in winter is usually called the number nine, which is the beginning of the ninth year. In northern China, there is a custom of eating jiaozi on the solstice in winter. As the saying goes, "When winter solstice comes, eat jiaozi." Of course there are exceptions. For example, Tengzhou, Qufu, Zoucheng, Linyi and other places in Shandong Province have the custom of drinking mutton soup on the same day, which means to drive away the cold. In the south, people eat jiaozi. Of course there are exceptions. Dietary customs vary from place to place, but eating jiaozi is the most common.

The ancients believed that since the winter solstice, the days have been getting longer and longer, the yang is rising, and the yang of heaven and earth is getting stronger and stronger, which represents the beginning of the next cycle. This is a good day.

Question 3: The date of winter solstice is 65438+ when is February every year? It is a fact that the winter solstice is the 20th or 22nd day of Gregorian calendar 65438+February 265438. Don't confuse it with geography and astronomy. Geography and astronomy require precision. Those who study geography naturally know the difference between sidereal day and Sun Day. Calendar calendar is naturally biased and geographically realistic. Moreover, the solar terms of the calendar are mainly formulated for the convenience of people's production activities, which is different from the scientific solar terms.

Question 4: Summer solstice and winter solstice are generally within one calendar year. The summer solstice is generally June 22nd, and the winter solstice is generally1February 22nd. However, due to the deviation of the earth's orbit around the sun, there will be a deviation in the real double solstice, which is why some years of the double solstice on the calendar will not be on the same day, but the general deviation is only a few hours, not too big, basically around the 22nd, sometimes 2 1, and sometimes the 23rd, but the 22nd is generally defined as the double solstice.

Question 5: When is the winter solstice? 20 15 open from winter to February 22nd 12: 49. The time of winter solstice is generally between the 20th and 23rd of the Gregorian calendar (65438+February, 265438+February), but the specific time of the day is uncertain. For example, on February 22nd, the winter solstice on 20 15 is public 12: 49, the winter solstice on 20 14 is public 12: 03, and the winter solstice on 20 16 is public12: 03.

The ancients said this about the winter solstice: As soon as the cathode arrived, the yang began to grow, the sun went south, the day was short and the shadow was long, so it was called "the winter solstice". The winter solstice is an important solar term of the China lunar calendar, one of the 24 solar terms, and a traditional festival of the Chinese nation. The winter solstice is usually called "Winter Festival", "Long Festival" and "Asian New Year". As early as more than 2,500 years ago in the Spring and Autumn Period, China had observed the sun with the earth and determined the winter solstice, which was the earliest of the 24 solar terms. The origin of the winter solstice actually comes from the planning of a national capital. As early as more than 3,000 years ago, Duke Zhou began to measure the shadow with the earth gauge method and measure the position of the world in Luoyi. This was a move of political significance at that time, but it became one of the festivals that affected future generations for thousands of years. Astronomy believes that the winter solstice is the beginning of winter. On this day, the northern hemisphere gets the least sunshine, 50% less than the southern hemisphere. This day is the first day of counting nine. In winter solstice, different places have different customs, and most places in northern China have the custom of eating jiaozi in winter solstice. After thousands of years of development, a unique seasonal diet culture has been formed from winter solstice to Sunday. Eating jiaozi has become the winter solstice custom of most people in China.

Question 7: Is the winter solstice the same day every year? 65438+February 2 1 or 65438+February 22

Question 8: Why is the winter solstice 65438+February 2 1 every year? Winter solstice is an important solar term in the China lunar calendar, and it is also a traditional festival of the Chinese nation. As early as more than 2,500 years ago in the Spring and Autumn Period, China had observed the sun with earth gauges and determined the winter solstice, which was the earliest of the 24 solar terms, and the time was between June 65438+February 2 1 ~23 in the Gregorian calendar every year. The winter solstice on 20 16 is 65438+2 1.

Winter solstice is the earliest of the 24 solar terms, but most people don't know that the origin of winter solstice actually comes from the planning of a national capital. As early as more than 3,000 years ago, Duke Zhou began to measure the shadow with the earth gauge method and measure the position of the world in Luoyi. This was a move of political significance at that time, but it became one of the festivals that affected future generations for thousands of years.

When the Duke of Zhou arrived in Luoyang, he measured that Luoyang was "in the world" by the method of returning to the soil, and then began to divine the country and the land. "History? According to Luogu, Duke Zhou inspected several places around Luoyang, and finally determined that Jianshui East, Hubei Water West and Hubei Water East are all "only Luoliang" (all good places to build a temple state). The historical fact that the Duke of Zhou chose the base site of Luoyi through the "investigation of returning to the land" was recorded in ancient books and was regarded as the law of sealing the country by later generations.

The purpose of "Topography of Tugui" is to find out "in the soil" (the center of China). The essence of this method is that "the tree is eight feet high and the summer solstice is five inches long;" On the solstice of winter, the scene is one foot, three feet and five inches long (that is, an eight-foot high benchmark is erected). On the summer solstice, the shadow at noon is 65,438+0.5 feet, and on the winter solstice, the shadow at noon is 65,438+03.5 feet). "The depth of the soil is measured, the shadow is positive, and the land is searched. It stops at four o'clock." What is measured by this method is the theoretical position of Luoyang and Luoyi in the soil.

Zhou people made detailed plans for Yizhoushu, the first national capital after the demise of Shang Dynasty, according to the world set by Duke Zhou? Zuo Luozai: "As a big city, it is surrounded by soil ... it is in Luoshui in the south and Mangshan in the north, thinking that the world is big." . After the national society (capital and ancestral temple) was completed, Duke Zhou formulated the national etiquette system in detail in the Rite and Music System, Famous Hall of Chengzhou. According to records, the first month of the Zhou Dynasty is winter and November, and the winter solstice is the beginning of the New Year. In other words, Duke Zhou chose the longest day in the "sun shadow" measured by the Tugui method as the New Year.

From meditation to Qin dynasty, winter is always the same as the beginning of the year. This is still the case in the Han Dynasty. There is a saying in Hanshu: "The sun shines on the winter solstice, so congratulations ..." In other words, people originally celebrated the winter solstice to celebrate the arrival of the New Year. The ancients believed that since the winter solstice, the sun be the spirit of heaven and earth began to flourish, representing the beginning of the next cycle, which was a lucky day. Therefore, later, during the Spring Festival, customs such as ancestor worship and family dinners often appeared on the winter solstice. The winter solstice is also called "off-year". First, it shows that the year is approaching and there are not many days left. The second is to show the importance of the winter solstice. As a festival, the winter solstice originated in the Zhou Dynasty, flourished in the Tang and Song Dynasties, and has been passed down to this day. The first month of the week calendar is November of the summer calendar. Therefore, the first month of the Zhou Dynasty is equal to today's November, so there is no difference between New Year greetings and He Dong. It was not until Emperor Wu of the Han Dynasty adopted the summer calendar that the first month was separated from the solstice in winter. Therefore, it can also be said that the "Winter Solstice Festival" began in the Han Dynasty, flourished in the Tang and Song Dynasties, and has existed ever since.

Astronomical coordinates

According to modern astronomical science, the sun moves to 270 degrees of the yellow meridian from the winter solstice, and the sun shines directly on the tropic of Capricorn (also known as the winter solstice daily line), and the sun is most biased towards the northern hemisphere. Therefore, the winter solstice is the most precious day and the longest night in the northern hemisphere. For all parts of the northern hemisphere, the winter solstice is also the day with the lowest sun height at noon all year round. As far as Beijing is concerned, the winter solstice is only 9 hours and 20 minutes a day, and the height of the sun is only 26 42'. After the winter solstice, the stars in the night sky are completely replaced by the stars in winter. From today, they will enter the ninth.

Note: The polar axis passes through the center of the earth and connects the north and south poles, with an included angle of 66.5 with the earth's orbital plane and perpendicular to the equatorial plane of the earth's rotation.

Lunar reference

My divination is called the winter solstice. Yi Yue: My late king and even the Japanese were closed to the outside world, so business travel was no good.

On the day of winter solstice, the northern hemisphere gets the least sunshine, 50% less than the southern hemisphere. Beijing's daylight saving time is only over 9 hours. But this day is the first day of counting nine, and it is not the coldest time. This is because there is atmosphere and water vapor on the surface of the earth, which can store heat, not "save or lose" but "accumulate heat". From winter to the future, although the solar altitude angle gradually increases, it is a slow recovery process, and the heat lost every day is still greater than the heat received. & gt
