| Abstract: | The history of Dingshuo is reviewed and the algorithm of Dingshuo is expressed with mordern mathematical language. A flow chart of Dingshuo algorithm for a computer program is given. The main steps are :compute Dingri, calculate the change of the Sun and the Moon,judge leap month and so on. It does the great groundwork for the further research. |
