这是一个国历与农历互相转的unit.
其中年份皆用民国年份, 请自行转换 (西元年-1911 = 民国年).
***************************************************************************
*国农历对映表之说明 : *
***************************************************************************
* 前二数字 = 闰月月份, 如果为 13 则没有闰月 *
* 第叁至第六数字 = 12 个月之大小月之2进位码->10进位 *
* 例如: *
* 101010101010 = 2730 *
* 1 : 代表大月(30天) 0 : 代表小月(29天) ==> 1月大2月小3月大.. *
* 第七位数字为闰月天数 *
* 0 : 没有闰月之天数 *
* 1 : 闰月为小月(29天) *
* 2 : 闰月为大月(30天) *
* 最後2位数字代表阳历之1月1日与阴历之1月1日相差天数 *
***************************************************************************
这对映表只有民国一年至民国一百年, 如不敷您的使用请按照上述之方式自行增加.
这个程式没有判断您所输入之年,月,日是否正确, 请自行判断.
如果转换出来之农历的月份是闰月则传给您的值是***负数***
如果农历要转换国历如果是闰月请输入***负数***
此版本为freeware version : 0.1
您可以自行修改, 但最好可以将修改过之程式mail一份给我.
