The Chinese "sexagenary cycle" , also known as the "Stems-and-Branches" , is a cycle of sixty terms used for recording days or years. It appears, as a means of recording days, in the first Chinese written texts, the Shang dynasty oracle bones from the late second millennium BC. Its use to record years began around the middle of the 3rd century B.C. The cycle, and variations on it, have been an important part of historical calendrical systems in other, Chinese-influenced Asian states, notably those of Japan, Korea and Vietnam. This traditional method of numbering days and years no longer has any significant role in modern Chinese time keeping or the official calendar. However, the sexagenary cycle continues to have a role in contemporary Chinese astrology and fortune telling. Each term in the sexagenary cycle consists of two Chinese characters, the first representing a term from a cycle of ten known as the Heavenly Stems and the second from a cycle of twelve known as the Earthly Branches . The first term combines the first heavenly stem with the first earthly branch . The second combines the second stem with the second branch. This continues, generating a total of 60 different terms , after which the cycle repeats itself. This combination of two sub-cycles to generate a larger cycle and its use to record time have parallels in other calendrical systems, notably the Akan calendar. The sexagenary cycle is attested as a method of recording days from the earliest written records in China, records of divination on oracle bones, beginning ca. 1250 BC. Almost every oracle bone inscription includes a date in this format. This use of the cycle for days is attested throughout the Zhou dynasty and remained common into the Han period for all documentary purposes that required dates specified to the day.
