问题制作日历

Question

我在 VBA 中遇到了日历问题。想要创建一个日历，根据 A22 和 B22 列中输入的日期显示/绘制从 2022 年开始的周数范围。当周数在月份之间重复时会出现问题。

Tydzien = Week
Sty = January 
Lut = February

Option Explicit

Sub Kolorowaniedaty()
    Dim rok As Integer
        rok = Left(Cells(22, 2), 4)
    
    Dim miesiacpocz As Integer
        miesiacpocz = Mid(Cells(22, 2), 7, 1)
    
    Dim miesiackon As Integer
        miesiackon = Mid(Cells(22, 3), 7, 1)    
    
    Dim Datapocz As Integer
        Datapocz = Application.WorksheetFunction.WeekNum(Cells(22, 2), 2)    
    
    Dim Datakon As Integer
        Datakon = Application.WorksheetFunction.WeekNum(Cells(22, 3), 2)
    
    Dim Rokzdaty As String
        Rokzdaty = CStr(Mid(Cells(22, 2), 3, 2))
    
    Dim Rok2022 As Byte
        Rok2022 = 22
       
    Dim kolumna As Byte       
    
    For kolumna = 1 To 20
    
    If Rokzdaty = Rok2022 And miesiacpocz = miesiackon Then
       Range(Cells(22, Datapocz + 4), Cells(22, Datakon + 4)).Interior.Color = vbYellow
       Else: Range(Cells(22, Datapocz + 4), Cells(22, Datakon + 5)).Interior.Color = vbYellow
    
    End If
    
    Next kolumna
End Sub

我无法从 excel 上传 Makro 和日历的图像，因为我没有足够的声誉点。如果有人可以通过私人聊天提供帮助，我将非常感激。它必须来自我的工作。

它应该标记 11 周，但它的显示只有 10 周。有什么建议吗？ [3]：https://i.stack.imgur.com/X8kwQ.png

迭代日期范围内的每一天，并在每个星期一或月份变化时增加列号。将列号存储在一个数组中，并将其用作查找来确定给定日期的列号。运行这是一个新的干净工作簿。
