Does the constellation look at the new calendar or the old calendar?

The twelve constellations spread from the west to China, belonging to the western culture, and calculated by the Gregorian calendar (internationally recognized Gregorian calendar). The date of birth of the constellation is based on the 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".
