Is the constellation calculated by solar calendar or lunar calendar?

Constellations must be calculated according to the solar calendar!

They may calculate according to this new constellation, but many people still use the old one. Maybe the playwright who wrote Gemini used a new one!

Due to the change of the earth's axis, the movement of the solar system and the movement of the stars themselves,

The position of the zodiac is very different from that of two thousand years ago.

The correct date after the change is as follows:

Sheep: 04/ 19-05/ 13

Taurus: May 6, 22.

Gemini: 06/23-07/2 1
