Heavenly Stems & Earthly Branches

Heavenly Stems and Earthly Branches are two sets of signs in a certain sequence, which were created by ancient Chinese people to calculate the history and record the chronological sequence of events. 

The Origin of Heavenly Stem and Earthly Branches

As early as about 2700BC, the ancestor of Chinese nation, Yellow Emperor (Huangdi), sent Da Rao Shi to create a calendar system. Da Rao Shi explored the rule of changes between sky and earth, as well as that of the four seasons. Then he created ten heavenly stems and twelve earthly branches to make combinations representing a sexagenary cycle. A year can be represented by the composition of two characters, one from the heavenly set, and one from the other. That is believed to be the start of the stem-branch calendar. Thus came a way of counting time which has been passed down through thousands of years.

Earthly Branches

Earthly Branches can be used to count time of years, months and hours. When counting years, people use them with the 12 Chinese zodiacs and strictly one Earthly Branch corresponds to one fixed zodiac. For example, our ancestors have divided a day and night into twelve sections and named each as a 'shi chen', which is equal to today's two hours and has a fixed Earthly Branch name. From 11 pm at night to 1 am is decided to be the first one - 'zi shi', then the second two hours 'chou shi', on the analogy of this.

Take the year of 2016 for example, 2016 can be described as 'Bing Shen', a combination of the third sign in Heavenly Stems and the ninth one in the Earthly Branches. Then the year of 2017 will be 'Ding You' - the fourth sign and the tenth one's association. 

The Four Pillar of Life (also the Eight Characters of Birth Time or 'ba zi' in Chinese) was very popular and mostly used in fortune-telling. In four pairs of year, month, day, and hour of a person's birth, each pair includes one Heavenly Stems and one Earthly Branchs. There are compatibility and incompatibility relations among the stems and branches. The expression of one's birth time in this way has always been vital especially when it is used for fortune foretelling.
