Is the constellation according to the lunar calendar or the national calendar?

Because constellations are transmitted from abroad, western astrology mainly calculates the "personal astrolabe" according to the astrology when an individual is born, such as the positions of the sun, the moon and five stars in the zodiac. We generally say: Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces are all classifications of western astrology! All aspects of time calculation should be calculated according to the solar calendar (Gregorian calendar).

Chinese astrology is based on twenty-eight nights (see twenty-eight nights in Sanyuanli) or twelve o'clock and the dividing line, observing the sky and its area, so as to predict the events that will happen in the state and country on the ground corresponding to this area; Predicting the fate of emperors and their families, China's astrology is called Wei Zi's number-playing.

The constellations we usually refer to are solar constellations.
