Is the constellation based on the lunar calendar or the new calendar?

Constellations are calculated according to the solar calendar. Calculated according to the date of birth on the ID card. The zodiac was spread to China from the west, so the date is calculated according to the western date. Constellation refers to one of the indispensable components of astrology, and also refers to a group of stars in the sky. Since ancient times, human beings have associated three or five stars with mythical figures or devices, which are called "constellations".
