Is the constellation based on the birth calendar or the old calendar?

Constellations are calculated according to the solar calendar (that is, the zodiac calendar, but we don't often use this term here), because the old calendar (lunar calendar and lunar calendar) is our own culture accumulated in China for thousands of years, so we should use the old calendar to calculate the zodiac and other things. Constellation is a culture handed down from Europe and America, where it is calculated by solar calendar.
