Hi @mazlumkacar,
In addition to what @ppr suggested, you could use a temparory excel file and in any cell use the NETWORKDAYS.INTL OR NETWORKDAYS as formula.

Then its simply to read the value from the excel cell you pasted the formula in. This way you get the total workingdays between two dates. Which you could use in your Date Difference logic or filter datatable.
