A business day is generally considered any day when most businesses, banks, government offices, and organizations are open and operating. In most countries, a business day typically runs from Monday to Friday, excluding weekends and public holidays.
The standard business day is usually 8 hours long, often from 9:00 AM to 5:00 PM. However, the exact length and working hours can vary depending on the industry, company, and location.
Understanding how long a business day is can help you manage deliveries, banking transactions, customer support requests, and business operations more effectively.
What Is a Business Day?
A business day refers to a working day during which normal business operations take place. It excludes weekends and official public holidays when offices are generally closed.
For example:
- Monday = Business Day
- Tuesday = Business Day
- Wednesday = Business Day
- Thursday = Business Day
- Friday = Business Day
- Saturday = Usually Not a Business Day
- Sunday = Not a Business Day
If a company says your order will arrive within “3 business days,” the count only includes working days.
How Many Hours Are in a Business Day?
The traditional business day consists of 8 working hours.
Common business schedules include:
- 9:00 AM – 5:00 PM
- 8:00 AM – 4:00 PM
- 8:30 AM – 4:30 PM
While 8 hours is the most common standard, some organizations may operate longer hours.
Examples

| Banks | 9 AM – 4 PM |
| Government Offices | 8 AM – 5 PM |

Why Are Business Days Important?
Business days are important because many services rely on them when calculating deadlines and processing times.
Examples include:
Shipping and Delivery
Courier companies often estimate delivery times using business days.
For example:
- Order placed on Monday
- Delivery promised in 2 business days
- Expected delivery: Wednesday
Banking Transactions
Bank transfers are usually processed during business days.
A transfer made on Friday evening may not be processed until Monday.
Government Services
Applications, permits, and official documents are often handled only during business days.
Customer Support
Many support teams operate only during standard business hours.
How to Calculate Business Days
Calculating business days is simple when weekends and holidays are excluded.
Example 1
If today is Monday and something takes 5 business days:
- Tuesday = Day 1
- Wednesday = Day 2
- Thursday = Day 3
- Friday = Day 4
- Monday = Day 5
Result: The deadline falls on Monday of the following week.
Example 2
If today is Thursday and delivery takes 3 business days:
- Friday = Day 1
- Monday = Day 2
- Tuesday = Day 3
Expected delivery: Tuesday.
Do Holidays Count as Business Days?
No, public holidays are generally not considered business days.
For example, if a national holiday falls on a Monday:
- Monday = Holiday
- Tuesday = First business day
This means processing times may be delayed.
Common holidays affecting business operations include:
- New Year’s Day
- Independence Day
- Christmas Day
- Labor Day
- National Public Holidays
Always check local holiday schedules when calculating business days.
Business Days vs Calendar Days
Many people confuse business days with calendar days.
Business Days
- Exclude weekends
- Exclude public holidays
- Usually Monday through Friday
Calendar Days
- Include every day
- Include weekends
- Include holidays
Example
A package promised in 5 calendar days from Monday would arrive on Saturday.
A package promised in 5 business days from Monday would arrive on the following Monday.
This difference can significantly affect timelines.
How Long Is 1 Business Day?
One business day usually means the next working day.
Examples:

- Friday → Monday (assuming no holiday)
If a request is submitted late in the day, processing may begin on the next business day.
How Long Is 2 Business Days?
Two business days means two working days after the starting day.
Examples:
Starting Monday
- Tuesday = Day 1
- Wednesday = Day 2
Starting Friday

The weekend does not count.

Example:
Starting Wednesday:
