A 'business day' is a day when companies and banks normally operate — usually Monday to Friday, excluding public holidays. Understanding the term avoids missed deadlines. Here is the explanation.
Standard Business Days
Monday–Friday are business days; Saturday and Sunday are not. Public holidays also pause 'business days' for banks and many companies.
Business Day vs Calendar Day
- Business day: working day (Mon–Fri, no holidays).
- Calendar day: every day including weekends and holidays.
Why It Matters
Bank transfers, refunds and legal notices cite business days ('within 3 business days' means avoid weekends/holidays). A Friday promise of '3 business days' lands Wednesday, not Monday.
Cross-Country Differences
Weekends differ in some regions (e.g. Middle East Fridays) and holidays vary — always confirm the local working calendar.
