Are the twelve constellations calculated according to the lunar calendar or the new calendar?

Constellations originated from western astrology, so they are solar calendars, that is, dates that pass quickly. First, you should know your date of birth in the solar calendar, and then compare it with the following information. If you only know the birth date of the lunar calendar, you can convert it into the birthday of the solar calendar before entering the information.

Constellations were introduced to China from abroad. In fact, there was also a constellation called Twelve Stars in ancient China, which was used to measure the position and movement of the stars, the moon and the sun, and divided the zodiac into twelve parts, so it was called Twelve Stars.

The twelve constellations were originally used for divination, and the pronouns on each constellation represent a certain direction of the universe. Later, people used to put twelve constellations, representing twelve personalities of people.

Because after all, not all people in the same constellation are the same, and twins are different. Moreover, the constellation only shows a large group, not a certain person, and the specific situation varies from person to person. Constellations represent the basic characteristics of a group. I believe that I am not superstitious and not completely credible, but I can still believe some basics.
