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

Constellations were introduced to China from abroad. In fact, in ancient China, there was a constellation called Twelve Stars, which was used to measure the positions and movements of the stars, the moon and the sun, and divided the zodiac into twelve parts, so it was called "Twelve Stars". So, are constellations divided according to the lunar calendar or the solar calendar?

The twelve constellations were introduced into China from the west, belonging to western culture, and are calculated by the solar calendar (the internationally recognized Gregorian calendar). If it is according to the lunar calendar, it is the "twelve stars" of China. China native culture "Zodiac" is calculated according to the lunar calendar, also called lunar calendar. The ancient calendars in China were all based on the lunar calendar.
