The whole sky is divided into constellation areas.

Astronomers divide the stars in the whole sky into several constellations by region.

The whole day is divided into 88 constellations. North 27, South 48, 13 Zodiac.

Shan Lan and Spirited Away in the wind: the zodiac is 13 instead of 12! Because of the precession of the earth, there is a Ophiuchus between Scorpio and Sagittarius, and the length of Ophiuchus crossing the ecliptic is more than 7 times that of Scorpio. Therefore, it is unscientific and unreasonable to set up Zodiac Palace 12 for the so-called horoscope fortune telling! If you are interested, you can see the systematic discussion of constellations in Introduction to New Astronomy. (Not an advertisement! I look fine)
