Report a calculation issue

A short example helps us reproduce the issue. Please include as many of these details as you can.

• The mode you used, either Add business days or Count between dates.
• The start date and either the end date or the number of business days you entered.
• Whether you excluded federal holidays, included the start or end date, or added custom days off.
• The result you saw and the result you expected.

If the dates are sensitive, use sample dates that reproduce the same issue.
