Is the constellation based on birthday, lunar calendar or solar calendar?

Constellations are calculated according to the solar calendar. Because the time of the lunar calendar changes every year. There is no solar calendar.

Astrology is constantly changing, and it will change every 3000 years. Because of the change of the earth's axis, the movement of the solar system and the movement of the stars themselves, the position of the zodiac constellation is very different from that before 2000.

Constellations are calculated according to the solar calendar.

The correct date after the change is as follows:

The thing is this: there is a ecliptic in the sky, which is the trajectory reflected by the plane of the earth's revolution around the sun in the sky. In other words, the sun runs on the ecliptic all the year round, and there are 12 constellations passing through the ecliptic. These twelve constellations are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius and Capricorn. That is, Aries Palace, Taurus Palace, Twin Uterus ... Because the sun runs on the ecliptic, it passes through an astrological house every other month in a year, so the ancients 2000 years ago linked people born on the date when the sun passed through this astrological house with that astrological house! For example, from March 22nd to April 2nd1is Aries, which means that the sun just passed by Aries on this date, but with the gradual change of the earth's rotation axis for thousands of years, the positions of these constellations in the starry sky are misplaced, which makes the time for the sun to pass through these constellations wrong by almost one month, that is, the day when the sun passes through Aries actually becomes April to May, and so on. In addition, it was not until 1928 that the International Astronomical Union unified all-sky constellations into 88. Before that, the division of constellations in the sky has been changing, some have been added, some have been cancelled, some have been merged, and some have been * *. Among them, Scorpio was later divided into two constellations, and a part of Scorpio was separated and became the current "Snake Man" constellation. Moreover, the area occupied by snake people is larger than Scorpio, but the evolution of these thousands of years has been preserved for historical reasons, so we still use the twelve-star palace and date set by the ancients thousands of years ago.
