How to calculate the constellation? From the day of birth?

Constellations are calculated according to the solar calendar at birth, that is, the Gregorian calendar.

In astrology, constellations refer to twelve equal regions on the ecliptic. Western astrology believes that astronomical phenomena reflect and dominate human activities according to the principle of "up and down effect", so the twelve constellations represent twelve basic personality types or emotional characteristics. It tries to explain people's character and destiny by birthplace, birth time and celestial position.

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. The twelve constellations begin in spring, that is, when the sun runs to the vernal equinox around March 20 every year, they will be sorted in order: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. 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. Constellation believes that the sun constellation represents people's natural personality, willpower and self-expression way. We can have a basic understanding of a person through the sun constellation, but to really understand a person completely, besides the sun constellation, we should also look at the house where the sun sets and the angle with other stars. Even if the sun signs are the same, they are influenced by different palaces and angles, so there are not only 12 kinds of personalities.

According to the moon sign, the moon sign is the place where the moon was born. The moon affects the tidal changes of the earth, and also affects human emotions, inner security, subconscious, spiritual level, family and clan influence, personal habits, eating habits, preferences, potential, ideals, imagination, acceptance, adaptability, intuition and temperament. The moon symbolizes mother. Through the moon constellation, we can know our attitude towards our mother and the influence her gives us. We can also see our attitude towards other women and the way men treat their wives. The moon constellation affects the subconscious, not the external personality, but the formation of personality. The moon constellation is most obvious in childhood and primary school. When you know something about life, you will hide it. Ascending constellation, Sun constellation and Moon constellation are the three constellations that have the greatest influence on one's personality. Ascending constellation is a constellation that rises on the eastern horizon at the moment you are born, representing a person's true self in personality, appearance and body shape. Usually around the age of 30, after a person really matures, his daily behavior, personality, preferences and appearance are all influenced by the rising constellation. If you want to know your rising constellation, you should calculate it from the specific date and time of birth and the latitude and longitude of the place of birth, just like the traditional birth of China people. Ascending constellation is the beginning of the first house of personal horoscope, which is particularly important and affects nature, health, appearance and personal preferences, as well as fate changes. You can see the stars all over the sky from your personal chart. Different stars are located in the house of life, and the position of each star affects your fortune. If the stars in the palace, the core of your life, are different, they have different meanings. Therefore, from the astrological point of view, it is relatively simple to look at a person's personality from the constellation, but it depends on the fate of a day, a month, a year or a lifetime, or on everyone's horoscope.
