So we better not go with a day-of-week parameter, but a date parameter, and have a list of workdays... a cursor, even better, which would contain all workdays. Then simply locate that date in the list (assuming we aren't starting off a day off) and then just skip n days - and return that record's date. Then we're depending only on the accuracy of this calendar.

I have done some work for this, in case Dmitry is interested, at https://bitbucket.org/atlopes/calendar. Having a method for calculating working days after a specific date seems a very interesting idea.

Of course, I think Dmitry is starting with a Date, it just gets transformed into a weekday for the purpose of the calculation.
