Earthly Branches
Encyclopedia
The Earthly Branches provide one Chinese
system for reckoning time
.
This system was built from observations of the orbit of Jupiter
. Chinese astronomers divided the celestial circle into 12 sections to follow the orbit of Suìxīng (Jupiter, the Year Star). Astronomers rounded the orbit of Suixing to 12 years (from 11.86). Suixing was associated with Shètí (η Boötis) and sometimes called Sheti.
In correlative thinking, the twelve years of the Jupiter cycle also identify the twelve months of the year, twelve animals (mnemonic
s for the system), directions, seasons, months, and Chinese hour in the form of double-hours. When a Branch is used for a double hour, the listed periods are meant. When used for an exact time of a day, it is the center of the period. For instance, 午 (the Horse) means noon or a period from 11am to 1pm. (The jie qi system provided single hours and 15-degree arcs in time and space.)
Chinese seasons are based on observations of the sun and stars. Many Chinese calendrical systems have started the new year on the first new moon
after the winter solstice.
The Earthly Branches are today used with the Heavenly Stems in the current version of the "traditional calendar
" and in Taoism
. The Ganzhi (Stem-Branch) combination is a fairly new way to mark time; in the Shang era it was the ten Heavenly Stems
that provided the names of the days of the week. The Branches are as old as the Stems (and according to recent archaeology
may actually be older), but the Stems were tied to the ritual calendars of Chinese kings. They were not part of the calendrical systems of the majority of Chinese.
Some cultures assign different animals: Vietnam
replaces the ox, rabbit, and sheep with the water buffalo, cat, and goat respectively; Japan
replaces the pig with the wild boar; Tibet
replaces the rat, ox, rabbit and rooster with the mouse, bull, hare and bird respectively. In the traditional Kazakh version of the 12-year animal cycle , the dragon is substituted by a snail
, and the tiger appears as a leopard .
s - (běi, north), (dōng, east), (nán, south), and (xī, west) - Chinese mariners
and astronomer
s/astrologers preferred using the twelve directions of the Earthly Branches, which is somewhat similar to the modern-day practice of English-speaking pilots using o'clock for directions. Since twelve points were not enough for sailing, twelve midpoints were added. Instead of combining two adjacent direction names, they assigned new names as follows:
Following is a table of the 24 directions:
Advanced mariners such as Zhèng Hé
used 48-point compasses. An additional midpoint was called by a combination of its two closest basic directions, such as (bǐngwǔ) for the direction of 172.5°, the midpoint between (bǐng), 165°, and (wǔ), 180°.
