java万年历、24节气算法---java算法实现
寿星万年历是我在网上见到的一份极高高精度的万年历，其采用先进的算法实现，其精度堪比刘安国教授为中国科学院国家授时中心制作的日梭万年历。但网络上只有javascript版本。于是自己将其翻译为java程序，并公布于此，方便大家使用。
关于寿星万年历相关简要描述如下：
寿星万年历是一款采用现代天文算法制作的农历历算程序，含有公历与回历信息，可以很方便的进行公、农、回三历之间的转换。提供公元-4712年到公元9999年的日期查询功能。其中1500年到1940农历数据已经与陈垣的《二十史朔闰表》核对；含有从公420元(南北朝/宋武帝元年)到今的基本年号。在过去几百年中，寿星万年历的误差是非常小的，节气时刻计算及日月合朔时刻的平均误差小于1秒，太阳坐标的最大可能误差为0.2角秒，月亮坐标的最大可能误差为3角秒，平均误差为误差的1/6。万年历中含有几百个国内城市的经纬度，并且用户可根据自已的需要扩展经纬度数据。
