Xia xiaozheng 夏小正 "The small calendar of the Xia" is the oldest astronomical and at the same time the oldest 'scientific' text of ancient China. It has been transmitted as a chapter of the classic text Da Dai Liji 大戴禮記. The bibliographical chapter Jingji zhi 經籍志 in the official dynastic history Suishu 隋書 lists the Xia xiaozheng as a separate text.

There is much dispute about the question whether the Xia xiaozheng was really a product of the Xia period 夏 (21th - 17th cent. BCE) or if it was written in later ages, but definitely the text existed already during the Spring and Autumn period 春秋 (770-5th cent. BCE), and it can be assumed that it goes back to much older sources.
For all the twelve months the short text Xia xiaozheng (it is only 463 characters long) notes down the configuration and movement of the stars (the constellations appearing at dawn and at dusk at the horizon, the direction of the ladle of the Big Dipper, or the appearance of the Milky Way), meterorological phenomena, phaenology as well as agricultural and political activities.
About the first month, for example, it is said that the star Ju 鞠 appears. At the beginning of dusk the constellation Shen 參 culminates. The tail of the "Northern Dipper" (beidou 北斗) points downwards. At that time favourable wind prevails. It is necessary that there is thunder in the first month. The farmer goes out as soon as the snow is melting. The frost fades, and people remove the remaining dirt. The hibernating animals wake up, the wild goose appears in the northern villages, the pheasant cries excitedly, the fish appear and break the ice, in the gardens sprouts the leek, the voles come out, the otters "offer" fish, the eagles behave like turtledoves. The willows push, the plums, abricots and peaches begin to flower, nodules cover the herb gao 縞, and the chicks breed and feed.
Unfortunately the text of the transmitted Xia xiaozeng is incomplete and here and there contains errors. A number of statements in the received text are quite confused, and indication that it has come into being over a long period of time. The descriptions of the constellations (with Ju 鞠 instead of Liu 柳, Huo 火 instead of Xin 心 and Chen 辰 instead of Fang 房) prove that parts of the text are very old, which can also be seen in the position of the seven stars of the Big Dipper that is different from reports of later times.
Furthermore, later commentaries on the main text have wrongly been incorporated into the main text in later editions, so that it is in some instances difficult to tell the original text from commentary text. In fact, the greatest part of the text consists of a brief original sentence some crucial terms of which are then explained. Therefore some scholars call the received text Xia xiaozheng zhuan 夏小正傳 "Small calendar of the Xia with commentary".
The most important commentators of the Xia xiaozheng were Fu Songqing 傅崧卿 (jinshi degree 1115; Xia xiaozheng Daishi zhuan 夏小正戴氏傳), Gu Fengzao 顧鳳藻 (fl. 1818; Xia xiaozheng jingzhuan jijie 夏小正經傳集解), Huang Pilie 黄丕烈 (1763-1825, comments on Fu Songqing's book), Ren Beilin 任北麟 (c. 1800, Xia xiaozheng buzhu 夏小正補注), Zhuang Shuzu 莊述祖 (1751-1816, Xia xiaozheng dengli wenju yinyi 夏小正等例文句音義), Hong Zhenxuan 洪震煊 (1770-1815, Xia xiaozheng shuyi 夏小正疏義), Gu Fengzao 顧鳳藻 (fl. 1821, Xia xiaozheng jingzhuan jijie 夏小正經傳集解), Wang Yun 王筠 (1784-1854, Xia xiaozheng zhengyi 夏小正正義) and Ma Zhengqing 馬徵慶 (fl. 1868, Xia xiaozheng jianshu 夏小正箋疏).
