Why do constellations follow the solar calendar?

Because the constellation points out the position of the sun in the starry sky at birth, according to the solar cycle.

In fact, it is basically consistent with the 24 solar terms in China.

Constellations are calculated according to the Gregorian calendar (solar calendar, national calendar, new calendar) date of the year of birth.

The boundary date and moment between two adjacent constellation are slightly different every year,

The date of the junction of the two constellations should be determined according to the year and time of birth.
