If I understand you right try this, it will put the date in the next row
down in column D when the workbook is opened

Private Sub Workbook_Open()
Range("D65536").End(xlUp).Offset(1, 0).Value = Date
End Sub

To put in this macro, from your workbook right-click the workbook's icon and
pick View Code. This icon is to the left of the "File" menu this will open
the VBA editor, in the left hand window double click on thisworkbook, under
your workbook name, and paste the code in the window that opens on the right
hand side, press Alt and Q to close this window and go back to your
workbook, now this will run every time you open the workbook. If you are
using excel 2000 or newer you may have to change the macro security
settings to get the macro to run.

Each time I open my worksheet, I make a new entry on the next empty row, I
want to have the date fill in on column D of the current row. I have tried
the NOW() and TODAY() together with IF(ISBLANK), but all previously
entered
dates update each time I re-open the sheet.

My question; is there a way to enter a date in a cell that will not update
each time I re-open the workbook, but rather go to the next row in that
column and enter a new date.

I hope I have explained that clear enough, I searched several groups and
only found 1 similar question with a single VB answer which was
nonfunctional according to a reply.
