Frequently asked questions
Are public holidays excluded from business days?
No. Business days count Monday to Friday only; public holidays differ by country and are not subtracted.
What does “include end date” mean?
From Monday to Wednesday is 2 days, or 3 days if you count both the first and the last day — as you would for hotel nights versus event days.
