When I am doing a monthly report, I need just the data of the current month, next month or previous month so I have to delete the months not in scope. For instance, when I am extracting data, I can have an issue starting during this month but not closed yet, depending of the report, I don’t want to count it because it is still opened.

When I use the macro ?

When I need to delete the entire row based on the date for my monthly report.

Copy the code below and paste it into your macro. You will see my comments in green if exist so follow the help to adapt to your need.

For a column keeping current month:

Sub test()
Dim Rang As Range
Dim Cell As Range
Dim Arr() As Long
Dim Num As Long
Dim i As Long
With ActiveSheet
' change B if your date in other column and for multiple columns put B:C
  Set Rang = Intersect(.Columns("B"), .UsedRange) 
End With
Num = 0
For Each Cell In Rang
  If IsDate(Cell.Value) Then
    ' add -1 for previous month or +1 for next month ie month(date) - 1
    If Cell.Value < Int(DateSerial(Year(Date), Month(Date), 1)) Then
      Num = Num + 1
      ReDim Preserve Arr(1 To Num) 
      Arr(Num) = Cell.Row
    End If
  End If
Next Cell
For i = Num To 1 Step -1
ActiveSheet.Rows(Arr(i)).Delete
Next i
End Sub

Checking cell by cell deleting current month:

Sub test()
Dim i As Integer
i = 2
' change 2 if your date not in column B and change 50 if you have more rows
Do While (Cells(i, 2).Value <> "") And (i< 50)
  If VarType(Cells(i, 2)) = vbDate Then
    ' add -1 for previous month or +1 for next month ie month(date) - 1
    If Cells(i, 2) >= Int(DateSerial(Year(Date), Month(Date), 1)) Then
      Cells(i, 2).EntireRow.Delete
    End If
  End If
i = i + 1
Loop
End Sub
