Why do the twelve constellations put Pisces last?

The dates of the twelve constellations are calculated according to the trajectories of celestial constellations. The sun is always in motion. When the sun runs, it will pass through the position of the constellation, and the person born in the area where the sun passes through is what constellation.

Therefore, the date division of the twelve constellations is also based on which constellation area the sun's trajectory passes through.

As we all know, the sun is always in motion, and its trajectory is called the ecliptic. And if the equator of the earth is infinitely extended to intersect with the ecliptic, one of the intersections is the "vernal equinox". From the vernal equinox, divide an area every 30 degrees to form an equal zodiac. And this vernal equinox is the starting point of the twelve constellations formulated by predecessors. On March 2 1 every year, the sun will come to the vernal equinox and enter Aries Palace.

According to this rule, Aries is the beginning. Then go down the ecliptic in turn, and Pisces is the last one. . No reason
