        {
            // fix for saturday.
            end = end.AddDays(-1);
        }

        if (end.DayOfWeek == DayOfWeek.Saturday && days > 0)
        {
            // add two days for landing on saturday
            end = end.AddDays(2);
        }
        else if (end.DayOfWeek < start.DayOfWeek)
        {
            // add two days for rounding the weekend
            end = end.AddDays(2);
        }

        // add the remaining days
        return end.AddDays(days + weekendDays - remainder);
    }
