中国公历算法不是太难，关键是星期值的确定。这里给出了简单算法： *^_yJA's5

根公历相比，中国农历的算法相当复杂。我在网上找的算法之中，eleworld.com 的算法是最好的一个。这个算法使用了大量的数据来确定农历月份和节气的分部，它仅实用于公历 1901 年到 2100 年之间的 200 年。 rj:,ai;E4

中国二百年年历 1901 年至 2100 年  zsc&o  
cEB}  
我用上面这个程式制作了二百年年历，1901 年至 2100 年，全部收录在这本书中。 #*~EU/f_K  
U"?/ }}s  
年历格式说明： a*Q0u(hj  
F<V-KJsb*  
农历日期列在公历日期后面。 JAT0?NXd  
节气用节气名称标明。 qoS=$  
农历每月第一天用月份名称标明。 YiK&q<>  
例如，2000 年一月的表达格式如下： li-|$B5E  
[HTML] ah_Qc$  
一月 日 一 二 三 四 五 六1/252/26 3/27 4/28 5/29 立春 腊月 8/ 29/ 3 10/ 4 11/ 5 12/ 6 13/ 7 14/ 8 15/ 916/10 17/11 18/12 19/13 20/14 雨水 22/1623/17 24/18 25/19 26/20 27/21 28/22 29/2330/24 31/25 [/HTML] Em\ly (hy
