Why is the constellation called metaphysics?

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 (solar constellations) is based on the intersection time of qi in the twenty-four solar terms, and the latitude and longitude of the birth area should also be considered, that is, the birth time (Beijing) should be converted into the real solar (astronomical) time to calculate.

The constellation originated from the primitive Babylonians on the Mesopotamian plain. They divide the ecliptic plane into 12 regions, which are called "zodiac signs" (see the above picture: zodiac signs, zodiac signs and 24 solar terms). The zodiac signs correspond to the twelve constellations respectively. The boundaries of the twelve constellations are divided according to the time points of qi (vernal equinox, Grain Rain, Xiaoman, summer solstice, summer heat, autumnal equinox, first frost, light snow, winter solstice, severe cold and rain) in the twenty-four solar terms of the lunar calendar (note: the twenty-four solar terms are divided into 12 qi and1). The order of the twelve constellations is: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Although western constellations and China's birth numerology are two completely different life fate prediction systems.

However, westerners' division of twelve constellations is strikingly similar to the division of twelve months (months) in horoscope fortune-telling invented by China. These two forecasting systems are based on the unique 24 solar terms in China calendar. The twelve months of the lunar calendar in China are based on 12 solar terms (beginning of spring, Jing Zhe, Qingming, Long Summer, Mangzi, Xiaoshu, beginning of autumn, Bailu, Cold Dew, beginning of winter, Heavy Snow and Slight Cold) and beginning of spring Point (beginning of spring is the first of the twenty-four solar terms in the lunar calendar, which means that the sun reaches the 365438 meridian).

Constellation is an astrology invented by westerners. Its principle is to take the earth (human) as a reference, and according to the relative positions and relative motion laws of the stars in the solar system (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.
