If I have a Start Date and End Date columns, how to I determine how many working days between them?

You can use the function NETWORKDAYS. To use this function you need to do the following:
1.Select Tools Add-in.
2.Checked the Tools Analysis Pack
3.Click the OK button.

CODE:
  1. NETWORKDAYS<span style="color: #66cc66;">(</span>start_date,end_date,holidays<span style="color: #66cc66;">)</span>

where
Start_date is a date that represents the start date.
End_date is a date that represents the end date.

Holidays is an optional range of one or more days (holidays) to exclude from the working calendar.

Example 1:
Start_date: August 17, 2006
End_date: August 21, 2006

CODE:
  1. = NETWORKDAYS(August 17, 2006,August 21, 2006)

The formula above will return 3. This means there are 3 working days between August 17, 2006 and August 21, 2006.
