Main Page | See live article | Alphabetical index The Chinese calendar is a lunisolar calendar formed by combining a purely lunar calendar with a solar calendar. Among Chinese, the calendar is not used for most day to day activities, but is used for the dating of holidays such as Chinese New Year (Spring Festival) and the Mid-Autumn Festival and for divination. The primary use in day to day activities is for determining the phase of the moon, which is important for farmers and is possible because each day in the calendar corresponds to a particular phase of the month. In China, the native calendar is the "farmer's calendar" (農曆 nónglì), as opposed to the "civil calendar" (公曆 gōnglì), or "Western calendar" (西曆 xīlì).

Most Chinese people notice that their Chinese and Western birthdays often fall on the same day on their 19th, 38th birthday etc The Chinese zodiac is completely different and is not used in the actual calculation of the calendar, but only in naming years. In fact, Chinese has a very different constellation system. The months are lunar months, such that the first day of each month beginning midnight is the day of the astronomical new moon. Each year has 12 regular months, which are numbered in sequence (1 to 12). A year may also have an intercalary month (闰月 rùnyuè), which may come after any regular month. It has the same number as the preceding regular month, but is designated intercalary. The Chinese solar year is divided into 12 parts that are equivalent to the sun signs of the tropical zodiac. Intercalary months are arranged so that the sun always enters Capricorn on the 11th regular month (month 11) of a year. If there are 12 months between two successive occurrences of month 11, one of these 12 months must be an intercalary month and it is the first of these 12 months during which the sun remains within the same zodiac sign throughout. The times of the astronomical new moons and the sun entering a zodiac sign are determined in the Chinese Time Zone by the Purple Mountain Observatory (紫金山天文台 Zǐjīnshān Tiānwéntái) in Nanjing. The Zodiac Sign in which the sun is in at the start of the month usually determines the number of a regular month: Month Zodiac Sign at Start 11 Sagittarius (by rule 4) 12 Capricorn 1 Aquarius 2 Pisces 3 Aries 4 Taurus 5 Gemini 6 Cancer 7 Leo 8 Virgo 9 Libra 10 Scorpio Some astronomers believed this correspondence to be always true, but there are exceptions. An exception occurred in 1985, after the sun had entered Capricorn and then Aquarius in month 11, causing the Chinese New Year to occur on 20 February 1985 in Pisces rather than Aquarius. The problem here is that there is a month in which the sun enters two signs of the zodiac. I'll refer to such a month as a dual-entry month. If a given month is a dual-entry month or has a dual-entry month before it and no earlier than the preceding month 11, the above correspondence may fail, otherwise it holds. Nomenclature The years are named by cycle of 10 Heavenly Stems (天干 tiāngān) and cycle of 12 Earthly Branches (地支 dìzhī). Each year is named by a pair of one stem and one branch called Stem and Branch (干支 gānzhī). Heavenly Stems are associated with Yin Yang (阴阳 yīnyáng) and 5 elements (五行 wǔxíng). Earthly Branches are associated with 12 animals (see Twelve Animals section). The 60-year cycle formed by combining the two cycles is known as a jiǎzǐ (甲子). It is not 120 because half of the combinations are unused. Jiǎzǐ is named after the first year in the 60-year cycle which is also called Jiǎzǐ. Some figures of speech use "jiǎzǐ" to mean "a full lifespan;" one who has lived more than a jiǎzǐ is obviously blessed. (Cf. the Biblical "three-score years and ten.") This 60-year cycle is insufficient for historical references. During feudal China, the Nian Hao (Era name of an emperor) is add in front of year name for distinction. Example, 康熙壬寅 (kāngxī rényín) (1662 AD) is the first 壬寅 (rényín) year during reign of 康熙 (kāngxī). The months, day, and hours can also be denoted using Heavenly Stems and Earthly Branches, though they are commonly addressed using numerals instead. Together, the four Stem and Branch pairs form the Eight Characters (八字 bāzì) used in Chinese astrology. There is a distinction between solar year and lunar year in the Chinese calendar because the calendar is lunisolar. Lunar year (年 nián) is from one Chinese new year to the next. Solar year (歲 suì) is from one Start of Spring to the next (see Jiéqì section). Lunar year is used exclusively because dates are also in lunar. Twelve Animals The Twelve Animals (十二生肖 shíèr shēngxiào, or colloquially 十二属相 shíèr shǔxiāng) representing the 12 Earthly Branches (地支 dìzhī) are, in order, the rat, ox, tiger, rabbit, dragon, snake, horse, sheep (or goat), monkey, rooster, dog, and pig. A legend explains the sequence in which the animals are assigned. Supposedly, the twelve animals fought over the precedence of the animals in the cycle of years in the calendar, so the Chinese gods held a contest to determine the order. All the animals lined up on the bank of a river and were given the task of getting to the opposite shore. Their order in the calendar would be set by the order in which the animals managed to reach the other side. The ox was fastest, but the rat had snuck up and climbed onto the ox's back. Just as the ox came ashore, the rat jumped off and finished the race first. The lazy pig came to the far shore last. And so the rat got the first year named after him, the ox got the second year, and the pig ended up as the last. See Chinese astrology for more details. Jiéqì Chinese months follow the phases of the moon. The part of the calendar that follows the movement of the sun is called jiéqì (節氣). Jiéqì is also translated to "Solar Terms". There are twenty four jiéqì. These jiéqì roughly fall on the same date in solar calendars such as Gregorian Calendar because they were solar based. Obviously these jiéqì do not form any pattern in the Chinese calendar. Before the Gregorian calendar was introduced to China, these jiéqì are published each year in farmers' almanac. Farmers relied on these jiéqì to plan their planting and harvest.
