The origin of constellations

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 these areas constellations. But westerners usually say that birthdays are calculated according to the solar 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, becoming the zodiac. In the counterclockwise direction, it is Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.
