सेक्साजेनरी चक्र

The Chinese sexagenary cycle (Chinese: 干支; pinyin: gānzhī) is a cyclic numeral system of 60 combinations of the two basic cycles, the ten Heavenly Stems (天干; tiāngān) and the twelve Earthly Branches (地支; dìzhī). These have been traditionally used as a means of numbering the years, not only in China but also in other East Asian nations like Japan, Korea, and Vietnam.

It was first developed in China, then imported through Korea into Japan. China has had a knowledge of eto since antiquity, but it was much later in the Western Han Dynasty (202 BC- 8 AD) that it was used in the calendar. According to Nihon shoki (日本書紀), the calendar was transmitted to Japan in 553. But it was not until the Suiko (推古) era around 602 that the calendar was used for politics.

The calendar is calculated by combining the jikkan (十干 the 10 stems) and jūnishi (十二支 the 12 branches). These two sets of terms were used to enumerate years of the civil calendar. Combining the series form a greater cycle of 60 terms, as the least common multiple of 10 and 12 is 60. The first term is formed by adding the first stem to the first branch, then the second stem to the second branch, and so on. If you start with kinoe-ne (甲子), so the 61st year would also be kinoe-ne. This was how the tradition of celebrating the 60th birthday (還暦) began. This counting system employing things of nature and animals create many myths, and people of Japan today still consider the good and bad luck of certain days and years.

The year 604, when the Japanese officially adopted the Chinese calendar, was the first year of the cycle. The year 1984 began the present cycle, and 2044 will begin another.

*The names of several animals can be translated into English in several different ways. The Vietnamese Earthly Branches use Cat instead of Rabbit/Hare.

In a traditional story of the twelve animals, the cat and rat were once good friends, but the animals to be selected to represent the years included the cat but not the rat. These animals had to present themselves to be given the honour of representing the years in the cycle, and the cat asked the rat to wake him up before they had to go. The rat didn't do this, but instead went himself. When they came to cross a river, the rat jumped on the ox's back, and just before the ox got to the bank, the rat jumped off and was first in line. This is why the twelve animals are lead by the rat, and because the cat was cheated out of its rightful place, rats are forever sought out by cats for revenge.

The sexagenary cycle was first used for days in the Shang Dynasty, and later also used for years and less commonly for months.

For example, the year 2000 was 17th year of the 78th sexagenary cycle, a gēng-chén year (庚辰年), a year of the Yang Metal Dragon. Therefore, 2006 is 23rd year of the 78th sexagenary cycle, called a bǐng-xū year (丙戌年), a year of the Yang Fire Dog.

The naming of the months and days is not common now, although they will be shown on Chinese calendars and almanacs.
