Constellation according to lunar calendar or solar calendar _ Constellation according to lunar calendar or solar calendar birthday

Is the constellation according to the lunar calendar or the solar calendar?

Constellations are calculated according to the solar calendar (new calendar).

The knowledge of constellations originated from Babylon, one of the four ancient civilizations. At that time, they divided the sky into many areas and called them "constellations". But westerners usually say that birthdays are based on the solar calendar (new calendar), so constellations are calculated according to the solar calendar.

Babylonians made a long-term prediction of these constellations, determined the ecliptic through observation, and divided it into 12 equal parts, which became the "zodiac".

These zodiac signs are named after the 12 constellation respectively. Starting from the vernal equinox, counterclockwise is Aries (Aries), Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius (Sagittarius), Capricorn, Aquarius (Aquarius) and Pisces.
