Your Team answered two questions with copy-able codes that I was able to get
to work seperately. (1) Entering time without ":" or "AM/PM" and (2) a
default to "PM" only upon entry/exit of cell - they're great! I never did a
macro before and it is cool!

Follwoing are the two macro codes so that you may tell me which lines to
delete/change.
MACRO-1
- - - - - - - - - - - - - - -
Private Sub Worksheet_Change(ByVal Target As Excel.Range)
Dim TimeStr As String

On Error GoTo EndMacro
If Application.Intersect(Target, Range("E8:F13,E18:F23")) Is Nothing Then
Exit Sub
End If
If Target.Cells.Count 1 Then
Exit Sub
End If
If Target.Value = "" Then
Exit Sub
End If

Application.EnableEvents = False
With Target
If .HasFormula = False Then
Select Case Len(.Value)
Case 1 ' e.g., 1 = 00:01 AM
TimeStr = "00:0" & .Value
Case 2 ' e.g., 12 = 00:12 AM
TimeStr = "00:" & .Value
Case 3 ' e.g., 735 = 7:35 AM
TimeStr = Left(.Value, 1) & ":" & _
Right(.Value, 2)
Case 4 ' e.g., 1234 = 12:34
TimeStr = Left(.Value, 2) & ":" & _
Right(.Value, 2)
Case 5 ' e.g., 12345 = 1:23:45 NOT 12:03:45
TimeStr = Left(.Value, 1) & ":" & _
Mid(.Value, 2, 2) & ":" & Right(.Value, 2)
Case 6 ' e.g., 123456 = 12:34:56
TimeStr = Left(.Value, 2) & ":" & _
Mid(.Value, 3, 2) & ":" & Right(.Value, 2)
Case Else
Err.Raise 0
End Select
.Value = TimeValue(TimeStr)
End If
End With
Application.EnableEvents = True
Exit Sub
EndMacro:
MsgBox "You did not enter a valid time"
Application.EnableEvents = True
End Sub
- - - - - - - - - - - - - - - - - -
MACRO-2
- - - - - - - - - -

On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range("F8:F13,F18:F23")) Is Nothing Then
With Target
If .Value < 1 Then
If .Value < 0.5 Then
.Value = 0.5 + .Value
End If
End If
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub
- - - - - - - - - - - - - - - - - - -

I'm so close to getting this to work - Can you help?
