The twelve constellations were invented by foreigners, right? Then foreigners use the solar calendar. We in China usually watch the lunar calendar on our birthdays. This is the lunar calendar we see.

In fact, there are three kinds, the solar calendar refers to the solar calendar, the lunar calendar refers to the monthly calendar, and the lunar calendar is the complex calendar of the 24 solar terms, so we generally refer to the lunar calendar.

However, the "solar calendar" corresponding to the lunar calendar is actually a "foreign calendar", which refers to the international calendar and is a kind of solar calendar.

China's solar calendar and lunar calendar are not used by professionals.

The twelve constellations are indeed foreign standards. After so many years of scientific transformation, the Gregorian calendar and the year of A.D. are very different from the original, closer to life and more convenient to use.

The early twelve constellations are foreign lunar calendars, which are called ephemeris oddly, because the calculation method is too complicated, and they are collectively called astronomical calendars. At home, they are related to the well-known Four Elephants, the Twenty-eighth Palace and Zhou Tianxing Jun, whose legendary name is Wei Zi.
