What is the scientific basis for the division of constellation dates?

Origin of Constellation: When naming stars, scientists deliberately divided constellations into similar celestial bodies, so there are Ursa Major, Ursa Minor, Scorpio and Virgo. Then why is nobody's constellation Ursa major? Because the earth's revolution revolves around the ecliptic plane, we can see the constellation 12 on the ecliptic plane, which is what we often hear about 12 palace. When the earth rotates to which constellation in this month, it is considered that the earth is in which constellation.

Now the position has changed, and the constellation is not accurate.

The latest constellation date division:

Aries: 04/ 19-05/ 13

Taurus: May 6, 22.

Gemini: 06/23-07/2 1

Cancer: July 22 -08/ 10

Lion: 08/11-09/16

Virgo: 09/17-10/31

Libra:111-1/23

Scorpio:11/24-1129
