Is the algorithm of constellation lunar or solar?

Because the constellation information is deeply rooted in people's hearts, many friends will check their constellations first when they go out. However, some friends say that their horoscope information is extremely accurate, and some friends say that their horoscope information is inaccurate. In fact, this is normal! Unlike the zodiac, the date range of the constellation has a fixed month, so it is normal to be unstable from time to time. But if everyone is wrong, it will not be a problem. Is the constellation calculated by lunar calendar or solar calendar?

According to the lunar or solar calendar, constellations are different from our ecliptic. The source of this constellation is ancient Babylon, one of the four ancient civilizations. As you can imagine, constellations depend on their definitions! Then, Babylon divided the sky into many areas called "constellations", while westerners usually say that birthdays are based on the solar calendar (new calendar), so constellations are calculated according to the solar calendar.

So according to our tradition, something is basically calculated according to the lunar calendar. Not according to this solar calendar, but generally speaking, I also follow this ability. After all, our traditional birthday is also calculated according to the lunar calendar, which is more accurate, so this date will not be confused.

And my friends are also counted according to the lunar calendar, and I am not the only one. If I am alone, I still feel a little bad, but everyone uses easy calculation, so I think we should use the lunar calendar. And I am a Gemini, and I am also very lively and cheerful.
