Western Horoscope and the Chinese Seasonal Segments (24 節氣)

The Western Astrology, the Zodiac or the Constellations are divided into twelve signs, each occupying approx. 30° of celestial longitude.

The Constellations are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.
This 12 signs form a celestial coordinate system, or more specifically an ecliptic coordinate system, which takes the ecliptic as the origin of latitude and the Sun’s position at vernal equinox as the origin of longitude.

Meaning, where the sun is, this is Constellation of reference. In other words, if the sun is at Aquarius, in the night sky (opposite to where the sun position) we could see Constellations like Cancer and Gemini as well as Orion.

Reference it to the chinese system, each Constellation span across 1 Jie Qi (節氣). Each Jie Qi (節氣) span around 30.4 days. This info is then place on the LuoPan (羅庚), each Jie Qi (節氣) taking 15 degree position, aligning to the 24 mountain for 太阳到山盤 application for auspicious date.

Both the Western and Chinese system in this aspect shares some similarities of using the sun as an object of reference to read the energy for each celestial block.
