Introduction
What are business days? This simple question has many practical answers. In this article, we explain what days count as business days. We cover shipping, legal, banking, and international contexts. You’ll also find “what days are business days” and “what days are considered business days” explained. Plus, we look at what are business days for shipping.
1. What Are Business Days?
Definition and general meaning
A business day means any day when most businesses are open. That usually means Monday through Friday, but not weekends or public holidays.
Different contexts matter:
- In legal usage, a business day excludes weekends and official holidays.
- In everyday meaning, it’s a weekday when businesses operate.
- Merriam-Webster defines it simply as “a weekday that is not a holiday.”
2. What Days Are Considered Business Days?
Typical days counted
In most countries, business days are Monday to Friday. They exclude weekends (Saturday and Sunday) and public or bank holidays.
Why it matters
People use this distinction for planning work, scheduling appointments, and calculating delivery times or deadlines.
3. Business Days vs. Working Days
Are they the same?
Often, people use “business days” and “working days” interchangeably. But they can differ:
- Business days refer to when businesses are open, typically Monday‑Friday.
- Working days depend on a person’s schedule or job. For example, healthcare or retail staff may work weekends even if those aren’t standard business days.
4. How Long Is a Business Day?
Time and hours
A business day often refers to a full calendar day of operation. In many cases, that means roughly 9 a.m. to 5 p.m., spanning about 8 hours.
Variation by business
Some businesses start earlier or end later. Hospitals, hotels, and transport services may operate 24/7. Yet, most use the 9–5 model for planning.
5. Business Days in Different Contexts
1. Legal and Contract Use
Contracts often define “business day” as any day other than weekends or bank holidays. Legal services and deadlines rely on this term to avoid confusion.
2. Banking and Financial Use
Banks and stock markets only operate on business days. That means transactions or settlements skip weekends and holidays.
3. Shipping and Delivery
For shipping, “business days for shipping” mean when carriers work—usually Monday to Friday, not counting holidays. This matters a lot for estimating delivery times.
4. International Business Days
Different countries have different weekend patterns. For example:
- Middle Eastern nations often work Sunday–Thursday.
- Some places include Saturday as a business day.
6. Why Business Days Matter
- Scheduling and planning: You need to know business days to set realistic deadlines.
- Financial operations: Banks and markets only work on business days.
- Shipping and services: Delivery estimates use business days to provide clarity.
- Clarity in contracts: Legal definitions reduce ambiguity and disputes.
7. How to Calculate Business Days
When you see “5 business days”, follow these steps:
- Start from today (or the next day).
- Count weekdays only.
- Skip public holidays.
- Example: If today is Monday and there’s no holiday, 5 business days later is next Monday. Delay if there’s a holiday.
Special cases: In the U.S., USPS counts Saturday as a business day for mail delivery.
