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
以下为代码:
