Are the twelve constellations calculated according to the lunar calendar or the solar calendar? When were the twelve constellations counted?

The twelve constellations are calculated according to the solar calendar. The saying of the twelve constellations comes from abroad and belongs to western culture. Each constellation is synonymous with a place representing the universe. Western countries use the Gregorian calendar to calculate time, so the twelve constellations are calculated according to the Gregorian calendar. Babylonians made a long-term prediction of the constellations in the sky, determined the ecliptic through observation, and divided it into 12 equal parts, which is the "zodiac".

The origin of 12 constellation

The origin of this constellation is said to be Babylon, one of the four ancient civilizations with China. At that time, they divided the sky into different regions and called them "constellations", which is the origin of constellations. Then the Babylonians observed these "constellations" for a long time. Through constant observation, they set the ecliptic and eventually divided it into twelve parts, resulting in the emergence of the "zodiac."

Distinguish between lunar calendar and solar calendar

The solar calendar is calculated by the sun and the lunar calendar is calculated by the moon. The lunar calendar is what we call the national calendar and the lunar calendar. It has been circulating in China for hundreds of years. The solar calendar comes from abroad, commonly known as the Gregorian calendar. The solar calendar is a calendar designed according to the earth's revolution around the sun, which originated in the west. The return year of one revolution is 365,438+0,897 days, so there will be one less day every four years.
