12 constellation ....

Constellations are calculated according to the solar calendar.

Because the constellation is the twelve constellations on the running route of the sun (that is, the ecliptic), that is, the solar calendar.

The zodiac is an area extending eight degrees from the orbit of the sun on the earth to both sides. In western astrology, there is a "return to the ecliptic" calculated by the vernal equinox, and in Indian astrology, there is a "stellar ecliptic" calibrated by fixed stars. The ecliptic is the track of the sun in the sky for one year, and it is also the star in the track of the great circle formed by the earth's orbital plane in the celestial sphere. Ancient astronomers were divided into different constellations according to these constellations, including eighteen constellations, fourteen constellations and twelve constellations. In ancient Babylonian astrology, 12 constellations which are easily divided into 30 degrees and 12 are regarded as zodiac signs, and different constellation totems (such as Sagittarius, Leo, etc. ) is based on different symbolic figures.

The sun is "yang", and the calendar based on the apparent movement of the sun is called "solar calendar";

The moon is "cloudy", so the calendar made according to the apparent motion law of the moon is naturally called "lunar calendar"

The lunar calendar in China is a combination of yin and yang-the lunar calendar is a traditional calendar adopted by China, also known as the summer calendar, the middle calendar and the old calendar, and it is also called the lunar calendar among the people. It uses the strict lunar cycle to determine the month, and sets the leap month to make the average length of a year close to the tropic year, which has the attributes of lunar month and solar year, so it is essentially a kind of yin-yang calendar. In the lunar calendar, the date when the sun and the moon meet (the ecliptic is equal) is the first day of the month, that is, the first day. The average length of the first month of the lunar calendar is about 29.53059 days, so some months are 30th. Call the moon big; Some months are the 29th, called abortion. The date of the beginning of the month is calculated according to the position of the sun and the moon, not mechanically arranged. The lunar calendar takes1February as a year, ***354 or 355 days, which is different from the tropic year 1 1 day. Therefore, coordination is achieved by inserting 7 leap months every 19 years. The arrangement of leap month is determined by the 24 solar terms.
