Understanding the Basics: What Is a Business Day?
The Standard Definition of a Business Day
A business day is a working day when companies, banks, and other organizations are open for business. Most commonly, this means Monday through Friday, excluding weekends and public holidays. Business days are often used to set deadlines, plan meetings, and organize deliveries.
Difference Between Business Days and Calendar Days
Calendar days count every day, including weekends and holidays. Business days only count weekdays that are not holidays. For example, if you order a book on Friday and shipping takes two business days, it may arrive on Tuesday, not Sunday.
Common Misunderstandings in the Modern Workplace
- Some people think business days include weekends, but they don’t in most countries.
- Public holidays can change business day calculations.
- International clients may have different ideas about what counts as a business day.
