Is the constellation calculated by solar calendar or lunar calendar?

Constellations are calculated according to the solar calendar.

The twelve constellations spread from the west to China, so the date is calculated according to the western date. Constellation refers to one of the indispensable components of astrology, and also refers to the combination of stars in the sky. Since ancient times, humans have associated the three or five stars with mythical figures or artifacts, which are called constellations.

The constellation originated from the primitive Babylonians on the Mesopotamian plain. They divide the ecliptic plane into 12 regions, which are called "zodiac signs", and the zodiac signs correspond to twelve constellations respectively. According to the neutral time point of 12 in the twenty-four solar terms of the lunar calendar, starting from the vernal equinox, the twelve constellations are arranged in the following order: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.

Constellation divination

The sun sign is the most frequently mentioned in astrology. As long as you know a person's date of birth, you can find out his sun sign. The orbit of the sun is called the ecliptic, and it is divided into 12 zones, each of which is 30 degrees. These 12 regions are what we call solar constellations. Everyone belongs to only one sun sign, because the time when the sun enters the palace is different every year. If the birthday is at the junction of the constellations, it is necessary to check the astronomical calendar to determine the sun constellation to which they belong, and there will never be a situation that spans two sun constellations.

Constellations believe that the sun constellation represents people's natural personality, willpower and self-expression. Through the sun sign, we can have a basic understanding of a person, but we should really understand a person completely. In addition to the sun sign, it depends on the house where the sun sets and the angle with other stars. Even if the sun signs are the same, the influence of the sun signs is different, so there are not only twelve kinds of personalities.
