Find cells from last month VBA

Question

First time asking a question here. I'm very new to VBA and therefore struggling.

I have 3 columns where I list up dates when I have completed a task. I need to find a way to save all information from last month to a PDF with a push of a button.

But, I can't find a way to only select cells from last month using VBA, and ignoring the cells from current month.

Export Last Month to PDF

Option Explicit

Sub ExportLastMonthToPDF()
    With ActiveSheet
        If .FilterMode Then .ShowAllData
        With .Range("A1").CurrentRegion
            .AutoFilter Field:=1, Criteria1:=8, Operator:=xlFilterDynamic
        End With
        .ExportAsFixedFormat xlTypePDF, "C:\Test\Test.pdf"
        .AutoFilterMode = False
    End With
End Sub
