Questions
Does it count the end date?
Not by default: Monday to Friday counts as 4 days. Tick "Include the end date" to count both ends, which gives 5.
How do I add business days to a date?
Choose "Add or subtract from a date", pick Business days (Mon–Fri) and enter the number. Weekends are skipped.
Are public holidays excluded from business days?
No — only weekends. Public holidays differ by country and state, so subtract any that apply to you.
