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

Astrologers in ancient western countries were mostly astronomers. According to the orbit of the sun and the earth, they divided the ecliptic plane into 12 equal parts every 30 degrees, resulting in 12 constellations. From the astrological point of view, when everyone is born, the position map of the stars in the sky forms a personal astrolabe, which includes ten planets such as the sun and the moon.
