I need some help, and I would like to appeal for it in this forum.

Suppose I have one list in a column as follows:

The list is a list of dates:

4/28/90
12/25/90
12/25/03
4/28/04
etc.
until 12/25/05

I would like to show all posible combinations of dates within the list in two new columns.

The first column should show the row being compared (sort of repetitive), and the second column should show the instance of the row being compared with.

For instance, if I take the first row in the column, then I would like to compare this first row against all the other rows in the list.

4/28/90 4/28/90
4/28/90 12/25/90
4/28/90 12/25/03
4/28/90 etc. until
4/28/90 12/25/05

When done with 4/28/90 I would like to continue with the next day in the first colum and again compare it with all the existing dates. For instance,

12/25/90 4/28/90
12/25/90 12/25/90
12/25/90 12/25/03
12/25/90 etc. until
12/25/90 12/25/05

So by now my new columns should look something like this:

4/28/90 4/28/90
4/28/90 12/25/90
4/28/90 12/25/03
4/28/90 etc. until
4/28/90 12/25/05
12/25/90 4/28/90
12/25/90 12/25/90
12/25/90 12/25/03
12/25/90 etc. until
12/25/90 12/25/05
and so on...

Is there a way of having Excel fill in the these columns other than cut and paste?
