Why are some of the twelve constellations only one day away, and they are another constellation?

In order to better observe the starry sky, Mesopotamian astrologers divided the stars with natural laws and distinctions into different regions, which were later constellations. Constellation refers to the stars in the sky.

Constellation is a process of random combination, but the International Astronomical Union divides the sky into 88 official constellations with precise boundaries, so that every star in the sky belongs to a specific constellation.

In western astrology, the zodiac is synonymous with the orientation of the universe, so the zodiac is divided into twelve constellations, called the zodiac.

Regarding the division of the time of the twelve constellations, I wonder if you have paid attention to a problem. Although two constellations may appear in the same month, the time of many constellations is coincident and has a time law.

Aries Taurus Gemini is 3 1 day, Cancer is 30 days, Lion is 3 1 day, Virgo is 30 days, Libra Scorpio is 20 days, Sagittarius is 28 days, Capricorn Aquarius Pisces is 29 days, just like our month, there are big and small, and February is divided into 28 and 29 days./kloc

Our month and year are judged according to the revolution and rotation of the earth.

Then it is very likely that the time occupied by a constellation is also determined by the change (or operation) of the star.

As we know, the constellation is a constellation community composed of groups of stars, and the movement of each star will naturally be reflected in the changes of the whole constellation. The change of stars leads to the change of constellations. We can observe them and then decide how many dates he will cross and how to start according to the changing rules of these constellations.
