First Year of the Rat

In Chinese tradition, the first year was the equivalent of 2637 BCE (although others give other dates). The Prime Minister of the first emperor, Huangdi (also known as the Yellow Emperor), is said in this year to have worked out the sixty-year zodiacal cycle. Part of this achievement was the discovery and incorporation of the nineteen-year so-called Metonic cycle which correlates lunar and solar dates, as part of the system (using leap months).

. According to one version of this tale, the emperor's advisors selected twelve candidates from among the animal types, including the rat and the cat. The winner was to be selected based upon merit, as to personal appearance, lifestyle, and contributions to the world. Before the competition, the cat asked the rat for a wake up call in order to get to the show on time; however, the rat apprehensive of the competition, especially as to the cat's apparent beauty, did not wake the cat, who then overslept (and, ever afterwards, the embittered cat became a ratter and a mouser). The Jade Emperor, mystified as to why only eleven candidate animals showed up, inquired of his servants. These servants hastily acquired the first possible replacement animal which they encountered, (a pig). After the start of the competition, the rat achieved first place by performing on the flute while upon the back of the ox. Impressed, the Jade Emperor placed the rat at the beginning of the twelve-year cycle (and the ox second, for being so generous as to allow the rat to play the flute upon the ox's back). Then the other animals were placed in order according to the Jade Emperor's judgment.

The zodiacal rat around the world

The zodiacal rat is known in other cultures besides China, in Asia and beyond. Generally, the rat/mouse is the first of a twelve-year animal cycle, although some of the other animals tend to vary. In Japan, the rat is known as ''nezumi'', and is the first in a twelve-year zodiacal cycle of animals. The Year of the Rat and the years of the subsequent other zodiacal animals is celebrated during
