About chinese zodiac

The Chinese zodiac, shengxiao (生肖) in Chinese, names each year of the lunar calendar after one of twelve animals, always in the same order: the Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog and Pig. Each animal’s page lists the years it holds from 1924 to 2031, with the dates each one begins and ends from the Hong Kong Observatory’s calendar tables, and explains where the animal’s place comes from and how other countries vary it. The five elements page shows how the animals combine with wood, fire, earth, metal and water into a cycle of sixty years, and the Fire Horse, the year that comes round once in sixty and last came in 2026, has a page of its own.

When the year changes

The animal changes at the Lunar New Year, the first day of the first month of the Chinese calendar, which Encyclopaedia Britannica places between 21 January and 20 February. The Hong Kong Observatory, which compiles Hong Kong’s calendars, has long used that day for the change, and China’s national standard for the calendar, issued in 2017, agrees with it. Fortune-tellers often count from Spring Commences (lichun), the solar term around 4 February, instead, the Observatory notes, which is why popular charts can disagree for people born between the two dates. Japan moved the cycle onto the solar calendar, Britannica records.

Twelve animals and sixty years

The animals belong to the twelve earthly branches, a Chinese system of counting years and hours in twelves to which the animals were later added, Britannica explains. The branches are paired with ten heavenly stems to name each year, starting from Jia-zi, so that each pair returns every sixty years, as the Observatory sets out: 2026 is Bing-wu, the year of the Horse. The stems carry the elements, wood for jia and yi and fire for bing and ding in the Huainanzi’s scheme, which is why 2026 is a Fire Horse.

How old the twelve animals are

The oldest known list is in a day book for choosing lucky and unlucky days, buried in 217 BC in a Qin tomb at Shuihudi in Hubei, which uses the animals to describe thieves. It differs from today’s list, the Wuhan University historian Yan Changgui points out: it has a deer for wu and a horse for wei, and no animal at all for chen, the dragon’s branch. A second Qin day book, from Fangmatan in Gansu, has differences of its own. In these texts the branches count days, not years. The Observatory dates the naming of years by animals to about AD 100, and Wang Chong’s Lunheng, from the same century, has long been taken as the first full record of the twelve. Readings of character by birth year are younger again: Ming Wilson of the Victoria and Albert Museum calls them a fairly recent development, though Yan finds people born in tiger years likened to tigers in the Taiping jing of the Han.

Across East and Southeast Asia

The cycle is kept well beyond China. Britannica notes it in North and South Korea, Cambodia and Singapore, and records local changes: in Japan the boar takes the pig’s place, in some parts of Thailand an elephant does, and in Thailand a naga, a serpent being, replaces the dragon. Vietnam has the water buffalo for the ox and the cat for the rabbit, so 2023 was a Year of the Cat there, as the Voice of America reported. In the United States the holiday is often called Chinese New Year, the Library of Congress notes, though Korean and Vietnamese Americans keep it too, as Seollal and Tết.
