calculating network days, with some dates omitted from exceptions - Excel - excel

Question

The following is a macro which collects data from data we import into certain tabs. When the macro is run it filters through the data and produces a new excel book with this new data. The person who created this is no longer with us. The macro works fine except I'm trying to add another column like the one that calculates network days called days since 1st auth less parked. Im wanting to add another which gives days since the start of the information being passed to us. Ie a column call 1st instructed less parked.

Where do you want it? IF you want it in the z column, for example, try:
Columns("Z:Z").Select
Selection.Insert Shift:=xlToRight
Range("Z1").Select
ActiveCell.FormulaR1C1 = "New formula"
Range("Z2").Select
ActiveCell.FormulaR1C1 = "=AA2-AB2"
Selection.AutoFill Destination:=Range("Z2:Z5000")
I don't understand the formula you need, but there's a template you can use... If you give us the formula we can put it the second last line?
