Whether the constellation is born according to the lunar calendar or the solar calendar,

The date of birth of the constellation is based on the Gregorian calendar. If it is at the junction of two constellations, it should be determined according to the date and time of birth in the Gregorian calendar.

The twelve constellations were introduced into China from the west, belonging to western culture, and are calculated by the solar calendar (the internationally recognized Gregorian calendar).

The twelve constellations were originally used for divination, and each pronoun represents a certain direction of the universe. Later, people used to put twelve constellations, representing twelve personalities of people. The birth time of each person, that is, the position of each star on the ecliptic, implies a person's innate character. The twelve constellations can reflect a person's psychological characteristics and symbolically represent a person's life behavior. Finally, the zodiac is divided into twelve constellations, which are called "Zodiac".
