in chronology, a cycle of twelve years; in use among the Turks and Cathayans.

Each year of the giagh bears a name of some animal: the first, that of a moufe; the second, that of a bullock; the third, of a lynx or leopard; the fourth, of a horse; the fifth, of a crocodile; the sixth, of a serpent; the seventh, of a horse; the eighth, of a sheep; the ninth, of a monkey; the tenth, of a hen; the eleventh, of a dog; and the twelfth, of a hog.

They also divide the day into twelve parts, which they call giaghs, and distinguish them by the name of some animals. Each giagh contains two of our hours, and is divided into eight kehs, as many as there are quarters in our hours.
