公农历转换VB类  clsDate
 
    网上流传很多计算公农历的源代码，很多，但是居然没有VB的，晕，
    所以。。。。。
   
    用法：
    以l开始的方法均为阴历，以s开始的方法均为公历
    基本的两个初使函数：
    lInitDate：用农历年月日初使化日期对象
    sInitDate: 用公历年月日初使化日期对象
   
    其它的方法看下面的一小段代码吧

示例代码   
Private Sub Command1_Click()
   Dim t As clsDate
   Dim y As Long
   Dim m As Long
   Dim d As Long
   Dim st As Single
   Dim et As Single
   Dim da As Date
   Dim j As Long
   Dim ret As Long
   Set t = New clsDate
   ''''t.sInitDate 1900, 1, 1
   t.lInitDate 2047, 5, 12, False   ''''农历2047年5月12日，非闰月
   Debug.Print t.lYear
   If t.IsLeap = False Then
      Debug.Print t.lMonth
   Else
      Debug.Print " 闰 " & t.lMonth
   End If
   Debug.Print t.CDayStr(t.lDay)  ''''农历日期中文大写
   Debug.Print t.GanZhi(t.lYear)  ''''求干支
   Debug.Print t.YearAttribute(t.lYear) ''''农历年的属相
   Debug.Print t.sYear '''' 公历年
   Debug.Print t.sMonth '''' 公历月
   Debug.Print t.sDay '''' 公历日
   Debug.Print t.sWeekDay ''''公历星期
   Debug.Print t.Era(t.sYear)'''' 公历纪元
   Debug.Print t.Constellation(t.sMonth, t.sDay) '''' 星座
   Debug.Print "Week:" & t.wHoliday '''' 按第几个星期几计算的假日
   Debug.Print "Solar" & t.sHoliday '''' 按公历计算的假日
   Debug.Print "Lunar" & t.lHoliday '''' 按阴历计算的假日
   Debug.Print t.lSolarTerm '''' 计算节气
  
   ''''以下为速度测试，很快吧。
   st = Timer
   With t
        For y = 1900 To 2049
           For m = 1 To 12
             For d = 1 To 28
                .lInitDate y, m, d, False
  
             Next
           Next
        Next
   End With
   ''''t.printf
   et = Timer
   Debug.Print et - st

   Set t = Nothing
End Sub
