What does 5 business days mean? Examples and calculator

Published 2026-04-26 · Updated 2026-05-01 · By John Heitzer

The short answer

Five business days usually means five working weekdays, normally Monday to Friday. Weekends are not counted. Public holidays may also be excluded depending on the company, country, or policy involved.

So if something starts on a Monday, 5 business days may land on the following Monday if the start day is not counted, or Friday if the start day is counted. This is why business day wording often creates confusion.

Example

If a parcel says it will arrive in 5 business days and the clock starts on Tuesday, the weekend normally does not count. That means the expected date may be the following Tuesday, not Sunday.

What can change the answer?

• Whether the first day is included
• Whether the deadline ends at close of business
• Whether bank holidays or public holidays are excluded
• Which country or region the company is using

The easiest way to avoid guessing is to use a calculator that lets you choose dates and exclude holidays where needed.

Real-world examples by industry

Shipping and ecommerce. A customer orders on Thursday afternoon with a "5 business day delivery" estimate. If the courier does not count weekends, the 5 business days run: Friday (day 1), Monday (day 2), Tuesday (day 3), Wednesday (day 4), Thursday (day 5). The parcel arrives the following Thursday — ten calendar days later. If there is a bank holiday on that Friday, add another day.

Customer service SLAs. A support ticket gets logged at 4pm on Wednesday. The team's SLA promises a response within 5 business days. If Friday is a bank holiday, day 1 is Thursday, day 2 is the following Tuesday (Monday is the substitute bank holiday), and day 5 lands on the following Monday. The customer sees an 11-day calendar gap and wonders why.

Invoice follow-ups. You send an invoice on Tuesday and the payment terms say "net 30 business days". Without considering the weekend, 30 business days from a Tuesday is roughly 6 calendar weeks away — but a December invoice will also skip Christmas Day, Boxing Day, and New Year's Day, pushing the due date further into January. Knowing which days do not count helps you plan cash flow more realistically.

5 business days examples

If the start day itself is counted, the result can be one working day earlier. That is why some companies say "within 5 business days" while others say "5 business days after" a date.

Is 5 business days a week?

Sometimes, but not always. If the period starts on a Monday and there are no holidays, five business days can fit inside one working week. If it starts later in the week, it usually crosses a weekend.
