'先以 H2B 函数还原成长度为 18 的字符串，其定义如下：
'前12个字节代表1-12月：1为大月，0为小月；压缩成十六进制(1-3位)
'第13位为闰月的情况，1为大月30天，0为小月29天；(4位)
'第14位为闰月的月份，如果不是闰月为0，否则给出月份(5位)
'最后4位为当年农历新年的公历日期，如0131代表1月31日；当作数值转十六进制(6-7位)

互联网是这个函数的作者？还是说摘自互联网？我搜了下，有个网页上的确有这个信息，我加上去。

农历转公历sGetDate这个函数该怎么用呢？要转换的农历格式是什么样的？

这个公历转农历好用，但农历转公历如何运用呢？公式如何表达？

ugyun · 发表于 2013-6-16 13:07

经测试，里面的自定义函数GetYLDate有问题，如农历日期1955年十月初一，对应的公历日期应为1955－11－14，但这个自定义函数显示为1955－11－13，再如农历日期2013年五月初一，对应的公历日期应为2013－6－8，自定义函数显示为2013－6－9，不知能不能修正，实际上上面那两个日期所在的农历月份公农历都对不上

农历转公历显示格式为2014年1月1日怎么改？现在是1204/1/1。
