How Does One Count Years?
Unlike most other calendars, the Chinese calendar
does not count years in an infinite sequence. Instead
years have names that are repeated every 60 years.
(Historically, years used to be counted since the
accession of an emperor, but this was abolished after
the 1911 revolution.)
Within each 60-year cycle, each year is assigned
name consisting of two components:
The first component is a Celestial Stemm. These
words have no English equivalent:
The second component is a Terrestrial Branch. The
names of the corresponding animals in the zodiac cycle
of 12 animals are given in parentheses.
||mao (hare, rabbit)
Each of the two components is used sequentially.
Thus, the 1st year of the 60-year cycle becomes jia-zi,
the 2nd year is yi-chou, the 3rd year is bing-yin,
etc. When we reach the end of a component, we start
from the beginning: The 10th year is gui-you, the 11th
year is jia-xu (restarting the Celestial Stem), the
12th year is yi-hai, and the 13th year is bing-zi
(restarting the Terrestrial Branch). Finally, the 60th
year becomes gui-hai. Since it takes 60 years to
complete a full cycle, almost everyone can meet the
exact same year again only once in lifetime.
This way of naming years within a 60-year cycle
goes back approximately 2000 years. A similar naming
of days and months has fallen into disuse, but the
date name is still listed in calendars.
It is customary to number the 60-year cycles since
2637 B.C.E., when the calendar was supposedly
invented. In that year the first 60-year cycle
