Does the constellation look at the solar calendar or the lunar calendar?

Look at the solar calendar by constellation.

Because the constellations come from the west, there are only the zodiac signs in the east.

Constellations come from the zodiac in astronomy ~ ~ ~ ~

The earth revolves around the sun once a year. When the earth rotates, the sun can be seen from the earth. The sun moves slowly on the celestial sphere and among the stars, and the direction of movement is the same as that of the earth's revolution, that is, from west to east, it also moves in a big circle every year, which is called solar annual apparent movement. The path of the sun's annual apparent motion on the celestial sphere is the ecliptic. In other words: the earth's orbital plane expands infinitely, and the great circle intersecting the celestial sphere is the ecliptic.
