How to&Answers:

Ideally there would be a column that has the date in it. Then you could do an advanced filter to filter on the date range that you require. Selecting the last 31 days will not always select just one month. It may select up to 3 days from the previous month as well.


Public Sub selectLastMonth()
  Dim ws As Worksheet
  Dim dStart As Date, dEnd As Date

  Set ws = ActiveSheet
  ws.Range("A:B").Sort key1:=ws.Range("A2"), header:=xlYes

  dEnd = ws.Range("A1").End(xlDown).Value
  dStart = DateSerial(DatePart("yyyy", dEnd), DatePart("m", dEnd), 1)

  ws.Range("A:B").AutoFilter field:=1, Criteria1:=">=" & dStart, Operator:=xlAnd, Criteria2:="<=" & dEnd

  Set ws = Nothing
End Sub

Answer:

use

LastRow = Sheet.Cells.SpecialCells(Excel.XlCellType.xlCellTypeLastCell).Row

then you can get the range from LastRow-31 to LastRow
if you have the date as specified then move the start point forward until the date value = date(if(now.month=1,now.year-1,now.year), if(now.month=1,12,now.month-1), now.day)
