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

Constellations can be born according to the solar calendar or the lunar calendar. Because the constellation is an astrology invented by westerners, westerners usually say that the date of birth is based on the Gregorian calendar, so most people think that the constellation is calculated according to the Gregorian calendar. For us in China, there are still two calendars in use, one is the international solar calendar, and the other is the lunar calendar handed down by our ancestors. There are some differences in time between the two calendars. In fact, these two calendars are essentially interlinked and can be converted to each other. Therefore, whether you know the solar calendar or the lunar calendar, as long as the date and time are accurate, you can calculate it correctly. ?

For example, a human (sheep) was born in Hangzhou, Zhejiang at 10: 20 on the first night of the seventh lunar month in 979. Then his constellations are: Sun Lion, Moon Lion, Rising Taurus, Descending Scorpio, Zenith Aquarius and Zenith Lion.
