Astronomical dating system
The Chinese followed a calendar of twelve lunar months, and calculated the year to be 365.25 days long.
They translated this 'magic' number into a unit of degrees, by setting the number of degrees in a circle equal to 365.25 (as compared to our use of 360 degrees).
Their version of the zodiac was called the 'yellow path', a reference to the sun traveling along the ecliptic.
As is the case with Western astrology, the Chinese had twelve houses along the yellow path, although the names they gave were different.
The Chinese were meticulous in recording other astronomical phenomena, such as comets, sunspots, novas, and solar flares, long before any other culture made any such observations.
They attempted to catalog every single star, defining their constellations by one major star, called the king, and surrounding it with princes.
One of the famous observations made by Chinese astronomers was that of a supernova in the year 1054.
C., and over hundreds of years of advanced sky watching, the Chinese became very adept at predicting lunar eclipses.To measure time, the Chinese divided the sky into 12 branches and 10 stems arranged around the ecliptic, to give a 60-year cycle.This particular system is believed to have been implemented by Emperor Huang Ti, whose reign began in about 2607 BCE.Chinese astronomy is fascinating in that it developed largely clear of the Indo-European sphere and developed its own particular methods and nuances.The Chinese were meticulous in keeping astronomical records, enabling modern historians to establish that Chinese astronomy remained largely unchanged from 1800 BCE onwards.
