Howdy. YOu can do with without VBA, if I understand correctly, and if they are setup exactly the same.
Insert two worksheets, one labeled First, the other Last. (Do not put anything on either. Then move all the previous day worksheets between the two. The setup a Summary worksheet, that is identical to the day worksheet, and move the Summary worksheet outside the First/Last combination. On the Summary worksheet, you can use a formula for instance, Totals (assuming Totals for each day worksheet is in same cell)
=SUM(First:Last!C2)
And so on for any other summary you need.
