Business Days vs Calendar Days
Calendar days include all days. Business days exclude weekends (and optionally holidays). A 14-calendar-day period is only 10 business days.
Adding Business Days
To add 10 business days to a date: skip weekends as you count. If you land on a weekend, move to the next Monday.
