Ever stare at your tracking info for a package and see it say “expected delivery in 3-5 business days,” and you just sort of wonder what that actually means? Especially when you order something on a Friday afternoon. Is Saturday one of them? What about that weird bank holiday next Monday? It’s a simple question that for some reason has a not-so-simple answer.

The whole concept seems straightforward but once you start looking closer it gets messy. It’s one of those terms we all use and assume we know, but the details can really trip you up, affecting everything from when you get paid to when your new couch will finally arrive. This whole thing is basically about setting expectations for time in the world of commerce and work.

So, What Exactly is a Business Day? The Simple Answer

Let’s not overcomplicate it from the start.

Normally, a business day is considered to be any day from Monday to Friday.

These are the days that most businesses and government offices are open for work.

Saturdays and Sundays? They don’t count.

They are the weekend, and typically, they are not business days.

So if something is going to take “one business day” and you order it Friday, you’ll probably get it Monday.

It is this basic Monday-to-Friday structure that forms the foundation of what we’re talking about.

The Gray Areas: When “Business Day” Gets Complicated

Okay so Monday to Friday seems easy enough.

But then life happens.

The real world has holidays, different time zones, and companies that just do things their own way.

This is where the simple definition starts to fall apart a little bit.

You have to look at the context of who you’re dealing with to get the real picture.

Public Holidays: The Big Exception

The biggest thing that messes with the Monday-to-Friday rule is public holidays.

A business day can’t be a day that most businesses are closed.

So federal holidays like New Year’s Day, Memorial Day, or Thanksgiving are definitely not business days.

Then you have state and local holidays which can make things even more confusing.

A day might be a business day in Texas but not in Massachusetts.

These are the days you have to subtract from your count when you’re waiting for something important.

Different Countries, Different Rules

The world is connected now, right?

We buy things from companies all over the globe.

What’s a business day here in the U.S. might be a weekend somewhere else.

For example, in some parts of the Middle East, the work week runs from Sunday to Thursday.

Friday is their day off.

So if you’re dealing with a company in Dubai, their “business day” schedule is completely different. This is something to keep in mind for international shipping or business.

Industry Specific Stuff

It is also true that some industries play by their own rules.

The banking world is a good example of this.

A bank’s business day might end at 3 PM for transactions to be processed that same day.

Anything after that cutoff time is considered the next business day.

Shipping companies like FedEx or UPS might operate on Saturdays, but they often don’t count it as a standard business day for their delivery estimates which is confusing.

How Business Days Affect Your Everyday Life

This isn’t just some boring term for accountants.

It actually shows up in your life all the time, you just might not notice it.

The definition of a business day can affect your money your packages and your deadlines.

Here are a few places you’ll see it pop up:

Online Shopping and Shipping: That “3-5 business days” for shipping is the most common one. It’s their way of telling you not to count the weekend while you wait.
Bank Transfers: When you transfer money, it often takes 1-2 business days to clear. A transfer on Friday night won’t even start moving until Monday morning.
Contract Deadlines: In legal or business contracts, a deadline of “10 business days” gives everyone a clear timeline that doesn’t include weekends or holidays.
Customer Support Responses: Many companies promise to get back to you within “2 business days.” This manages expectations so you’re not waiting for an email on a Sunday.

The Future of the Business Day in 2025 and Beyond

The idea of a strict Monday-to-Friday, 9-to-5 schedule is getting a bit old-fashioned.

With remote work becoming so normal, the lines are getting blurry.

The 4-day work week is also a thing some companies are trying out.

Does this change what a business day is?

Generally, not yet for official stuff like banking and shipping.

The old definition is still what most systems run on for now.

But as more companies change how they work, we might see the official definition start to bend a little.

For now, it is best that you assume the traditional Monday-to-Friday definition unless a specific company tells you something different. It’s just the safer bet.

Frequently Asked Questions (FAQs)

What is a business day?

Typically a business day is a weekday, from Monday through Friday. It does not include public holidays or weekends. This is the standard for most industries like banking and shipping.

Is Saturday a business day?

No, normally Saturday is not considered a business day. While some companies, especially in retail or shipping, might be open for business on Saturday, for official purposes like calculating deadlines or bank transfers, it’s treated as part of the weekend.

What is the difference between a business day and a working day?

The terms are often used to mean the same thing. A “working day” usually refers to any day an individual works. But “business day” is more official and almost always means Monday to Friday, minus public holidays. A plumber’s working day might be Saturday but it’s not a banking business day.

Do business days include holidays?

No, they do not. A key part of the definition is that business days exclude federal, state, and sometimes local public holidays. If a delivery is due in 3 business days and there’s a holiday in between, that adds an extra day to the wait.

Are business days the same for all companies?

Mostly, yes, but not always. The standard is Monday to Friday, but some companies, particularly those with 24/7 operations or global offices, might have their own internal definitions. Always check a company’s specific terms if a deadline is tight.
