Allen Tsai has put together some interesting observations on the Solstice patterns.
Then they found the length of a year is around 365.25 days.
|The Ecliptic is the Sun’s apparent path around the Earth. It’s tilted relative to the Earth’s equator. The value of obliquity of the Ecliptic is around 23 26′ 19” in year 2000.|
By rotating the Sun chart and positioning the Winter Solstice at the bottom, it will look like this . The light color area which indicates more sunlight is called Yang (Sun). And then interpretations began. The dark color area has less sunlight (more moonlight) and is called Yin (Moon). Yang is like man. Yin is like woman. Yang wouldn’t grow without Yin. Yin couldn’t give birth without Yang. Yin is born (begins) at Summer Solstice and Yang is born (begins) at Winter Solstice. Therefore one little circle Yin is marked on the Summer Solstice position. Another little circle Yang is marked on the Winter Solstice position. These two little circles look like two fish eyes.
How far back these early observations go is unknown. Many summaries of Yin and Yang ignore this early source in astronomy observations.
But here we are: late December, 2013. (son). Yang Chi begins to grow inside the ground. The seed begins to absorb water and grow too.
