use

WorksheetFunction.Min(Range("B:B"))

and

WorksheetFunction.Max(Range("B:B"))

To clarify i will have an input box asking for a start date and end date. i then need to find the 1st row with the start date and the last row with the end date.

here you go

Sub test()


Dim dt1 As Date, dt2 As Date
Dim str1 As String, str2 As String
Dim rng As Range


    dt1 = InputBox("enter start date")
    dt2 = InputBox("enter end date")
   
   

    For Each rng In Range("B1:B100")
   
        If CDate(rng.Value) = dt1 Then str1 = "Start date of " & dt1 & " is in row " & rng.Row
        If CDate(rng.Value) = dt2 Then str2 = "End date of " & dt2 & " is in row " & rng.Row
       
    Next rng
   
    MsgBox str1 & vbCrLf & str2

End Sub

sorry slight change so you always get the first row where it finds it for the start date and the last row where it finds the end date as you asked in your questions


Sub test()


Dim dt1 As Date, dt2 As Date
Dim str1 As String, str2 As String
Dim rng As Range


    dt1 = InputBox("enter start date")
    dt2 = InputBox("enter end date")
   
    For Each rng In Range("B1:B100")
        If CDate(rng.Value) = dt1 Then
            str1 = "Start date of " & dt1 & " is in row " & rng.Row
            Exit For
        End If
    Next rng
   
    For Each rng In Range("B1:B100")
        If CDate(rng.Value) = dt2 Then str2 = "End date of " & dt2 & " is in row " & rng.Row
    Next rng
   
    MsgBox str1 & vbCrLf & str2

End Sub

Wobbled, instead of looping you can use

            str1 = "Start date of " & dt1 & " is in row " & worksheetfunction.match(dt1,range("B:B"),0)

Hi Ssagibh you are correct - the only reason I went for the loop was to pick up the first and last instances.  If I'm right, the match function will only find the first instance?

so a better way of writing my code would be

Sub test()


Dim dt1 As Date, dt2 As Date
Dim str1 As String, str2 As String
Dim rng As Range


    dt1 = InputBox("enter start date")
    dt2 = InputBox("enter end date")
   
    str1 = "Start date of " & dt1 & " is in row " & worksheetfunction.match(dt1,range("B:B"),0)
   
    For Each rng In Range("B1:B100")
        If CDate(rng.Value) = dt2 Then str2 = "End date of " & dt2 & " is in row " & rng.Row
    Next rng
   
    MsgBox str1 & vbCrLf & str2

End Sub

I get the Error "Unable to get the match property of the worksheetFunction class" on the line
str1 = "Start date of " & dt1 & " is in row " & WorksheetFunction.Match(dt1, Range("B:B"), 0)

Attache is the sample from my workbook.

I looked for start date = 02/01/2008 and end date = 02/01/2008

but get error.

@ssaqibh This throws up an error as the loop suggested works fine.
