真正的公农历转换类for VB

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

End With

't.printf

et = Timer

Debug.Print et - st

Set t = Nothing

End Sub
