Does the constellation follow the lunar calendar or the solar calendar?

Are the dates of the twelve constellations divided according to the solar calendar (Gregorian calendar) or the lunar calendar (lunar calendar)? Some people think that the dates of the twelve constellations are divided according to the solar calendar (Gregorian calendar), while others think that the dates of the twelve constellations are divided according to the lunar calendar (lunar calendar). In fact, these two statements are not appropriate. In fact, the accurate division of the twelve constellations (sun constellations) is based on the intersection time of qi in the twenty-four solar terms. In addition, we should also consider the latitude and longitude of the place of birth, that is, the time of birth (Beijing) should be converted into real solar time (astronomical time) to calculate.

The constellation originated from the primitive Babylonians in Mesopotamia. They divide the ecliptic plane into 12 regions, which are called "zodiac signs" (see the above picture: zodiac signs, 24 solar terms), and the zodiac signs correspond to 12 constellations respectively. According to the twenty-four solar terms of the lunar calendar (note: the twenty-four solar terms are divided into 12 solar terms and 12 solar terms), 12 solar terms (vernal equinox, Grain Rain, Xiaoman, summer solstice, summer solstice, first frost, light snow, winter solstice, severe cold and rain) are used to divide/kloc-. When the sun reaches yellow) Although the western horoscope and China's life science are two completely different systems to predict the fate of life, the division of the twelve horoscope by westerners is strikingly similar to the division of the December order (month) in birthdates invented by China. These two forecasting systems are unique 24 solar terms created based on China calendar. The twelve months of the lunar calendar in China are divided according to twelve of the twenty-four solar terms (beginning of spring, Shangding, Qingming, Changxia, Mangzhong, Xiaoshu, beginning of autumn, Bailu, Cold Dew, beginning of winter, Heavy Snow and Slight Cold). The starting point is beginning of spring Point (beginning of spring is the first day of the 24th solar term of the lunar calendar, that is, when the sun reaches 3 15 degrees), and there are twelve of them.

Constellation is an astrology invented by westerners. Its principle is to take the earth (human) as a reference object, and according to the relative positions and motion laws of various stars in the solar system (such as the sun, the moon, Uranus, Mercury, Neptune, Pluto, Mars, Venus, Saturn, Jupiter and other planets), study and analyze the influence of these motion laws on human life, and explain people's character and destiny through the time and place of birth.

We all know that the sun is the largest star in the solar system, accounting for 99.8% of all the stars in the solar system, and it is the source of all the light and heat in the solar system. As the saying goes, "Everything grows on the sun", which means that life on earth depends on the energy of the sun to survive. It shows the importance of the sun in the solar system. So we usually talk about the constellation of the sun. Sun constellation is a constellation (region) in which the sun passes through the zodiac when a person is born.
