Is the constellation calculated by ephemeris or lunar calendar?

Constellations are calculated according to the solar calendar. The solar calendar is a new calendar. Birth constellation comes from astrology, trying to explain people's character and destiny by using their birthplace, birth time and celestial position. The birth month corresponds to the sun constellation as follows. Because the orbit of celestial bodies is different from the Gregorian calendar, the difference between different years will be 1-2 days, which is consistent with the distance between "solar terms" in the twenty-four solar terms of the China lunar calendar. The calculation of solar term time is accurate to minutes (not midnight), which is also the boundary of the constellation and changes every year.
