Why should birthdays be counted according to the constellation? How did the constellation 12 come from? When and where was it recorded?

The name of the constellation comes from Greek mythology. Greek mythology originated in ancient Greece and has been passed down orally for a long time, which made the Greek people create it collectively. The ancient Greeks worshipped deeply, but they didn't give it too high. They did not regard the gods as moral standards, but reported them as a reflection of life: because of thousands of years of struggle, the positions of the stars have changed, and the constellations have deviated from their original positions compared with thousands of years ago. Some people use the topics on some forums to speculate on redefining the birthday constellation. Today's stars began to change two thousand years ago, not with each passing day, and the division of constellations two thousand years ago was not very clear. The following information is about the division of constellations: 15000 years ago, people in ancient times divided 12 constellations in order to distinguish directions when sailing; With the evolution of more than 5000 years and the research of many numerologists, 12 constellation has become the standard for many people to measure their specific personality. After more than 2000 years of improvement, it has been recognized by more and more friends. The division of constellations five thousand years ago only determined the position of celestial bodies in the sky, and the relationship between human personality and them was finally determined through the long history of human civilization and the long research in the course of two thousand years. For example: Aries: March 21~ April 20. This date was not set after 5000 years, but people decided the sex for most people according to their personality and named them after the corresponding constellations in the sky. So, when was this date set? Obviously not thousands of years ago. Second, at the beginning, the zodiac had 12 constellations, and the zodiac was divided into 12 on average, which was called 12 palace. At this time, the zodiac and 12 are indeed one-to-one correspondence, so people are used to calling their horoscopes constellations. Due to the change of constellation division, there is an Ophiuchus next to Scorpio, and the "foot" has reached the zodiac area, so now there are indeed 13 constellations in the zodiac, but there is still only 12, and there is no change. Constellation theory based on the influence of planets near the Astral Palace on the personality of people born in this Astral Palace area. The movement of the constellation was not completed in an instant today. In its changes, people are also revising the personality attributes of the constellation to which people belong. Third, to sum up the above two points, whether from the position of stars, the division of constellations and the establishment time of constellation theory, your constellation is still the original constellation; Aries: March 2nd1~ April 20th Taurus: April 2nd1~ May 2nd1Gemini: May 22nd to June 22nd Cancer: June 22nd to July 22nd. ...........................................................................................
