AutoHotkey移植公历转农历函数代码如下(作者：海盗)：

/*
公历转农历：
输入公历，输出农历
农历（天干地支属相日期）:=Date_GetLunarDate(公历日期 YYYYMMDD)
 
*/
Date_GetLunarDate(Gregorian)
{
	;1899年~2100年农历数据
	;前三位，Hex，转Bin，表示当年月份，1为大月，0为小月
	;第四位，Dec，表示闰月天数，1为大月30天，0为小月29天
	;第五位，Hex，转Dec，表示是否闰月，0为不闰，否则为闰月月份 	
	
	;倒数第三位是农历闰几月，直接读取。
	;倒数第四位也即正数第四位，是闰月天数,1为大 30天， 0为小29天。
	 
 
	;举例2017年的5171680的前3位517,转成二进制010100010111,表示当年1-12月大小情况。第5位6，第4位1     表示2017年闰六月 大。 
	;测试用例：20170920 输出八月初一 
	;测试用例：20330828 输出八月初四
