Has the date of the constellation really changed?

Just as some ethnic groups in East Asia define a person's zodiac according to the animals represented by the year of birth, in many countries, a person's birth month corresponds to a constellation. 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.
