Workdays Calculation

Workdays Calculation

Hi everyone,

I've created a function to calculate the number of workdays between two dates.
I use it to measure how many weekdays have passed since a record in our action log was opened.

Previously, I was using the function suggested here. 
But this function is recursive and after a record was open more than around 50 days, the stack limit would be reached.

Have a look at my new function below. 
The only limitation I can see is that any holidays are not taken into account.
What do you think?

  2. int Diff_Calc(date startDate)
  3. {
  4.     today = zoho.currentdate;
  5.     totDiff = days360(input.startDate,today);
  6.     diffDiff = (floor((totDiff  /  7))  *  2);
  7.     actualDiff = (totDiff  -  diffDiff);
  8.     startDayofWeek = input.startDate.getDayOfWeek();
  9.     endDayofWeek = today.getDayOfWeek();
  10.     if (startDayofWeek  >  endDayofWeek)
  11.     {
  12.         Correction = -1;
  13.     }
  14.     else if ((startDayofWeek  ==  1)  &&  (endDayofWeek  ==  7))
  15.     {
  16.         Correction = 0;
  17.     }
  18.     else if ((startDayofWeek  ==  1)  ||  (endDayofWeek  ==  7))
  19.     {
  20.         Correction = -1;
  21.     }
  22.     else
  23.     {
  24.         Correction = 1;
  25.     }
  26.     correctDiff = (actualDiff  +  Correction);
  27.     return correctDiff;
  28. }
