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

This is a question that many friends who have just met the constellation will have. Constellations are calculated according to the solar calendar (new calendar), which is for sure.

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.

Your horoscope: The time when you were born is where the sun is when it passes through the zodiac, and that is your personal horoscope.
