delete duplicate rows, keep latest date and time group
 

Trying to get rid of duplicate rows, and keep only the latest date/
time group. Currently it gives me the earliest date/time group. I
have researched past posts, but they all seem to keep the earliest
date.

What do I need to change in the code below, or possibly you can
suggest a different way of doing it. Thanks.


Dim Col As Integer
Dim r As Long
Dim C As Range
Dim N As Long
Dim V As Variant
Dim Rng As Range

Range("A1").Select

Application.Calculation = xlCalculationManual
Col = ActiveCell.Column

If Selection.Rows.Count 1 Then
Set Rng = Selection
Else: Set Rng = ActiveSheet.UsedRange.Rows
End If

N = 0
For r = Rng.Rows.Count To 1 Step -1
V = Rng.Cells(r, 1).Value
If Application.WorksheetFunction.CountIf _
(Rng.Columns(1), V) 1 Then
Rng.Rows(r).EntireRow.Delete
N = N + 1
End If
Next r
