Introduction
Understanding how many business days in a year can help professionals, business owners, and employees manage schedules, project timelines, and financial planning effectively. Since business days exclude weekends and public holidays, calculating the exact number of business days in a year requires consideration of various factors.
In this blog, we will break down the concept of business days per year, discuss influencing factors, and provide a step-by-step method to calculate them accurately.
What Are Business Days?
A business day refers to a working day when businesses, banks, and institutions typically operate. It excludes weekends and public holidays.
- In most countries, business days are Monday through Friday.
- Saturday and Sunday are usually considered non-business days.
- Some industries, such as retail and healthcare, may have different definitions of business days based on their operations.
How Many Business Days in a Standard Year?
A standard year has 365 days, and a leap year has 366 days. To calculate business days, we follow these steps:
Step 1: Count Total Days in a Year
- Regular Year: 365 days
- Leap Year: 366 days
Step 2: Subtract Weekends
Since each week has 7 days and Saturday-Sunday are weekends, we calculate:
- 52 weeks × 2 weekend days = 104 weekend days
- Business Days in a Regular Year: 365 – 104 = 261 business days
- Business Days in a Leap Year: 366 – 104 = 262 business days
Adjusting for Public Holidays
Public holidays vary by country and region, impacting the total business days in a year. Common U.S. federal holidays include:
- New Year’s Day – January 1
- Martin Luther King Jr. Day – Third Monday of January
- Presidents’ Day – Third Monday of February
- Memorial Day – Last Monday of May
- Independence Day – July 4
- Labor Day – First Monday of September
- Columbus Day – Second Monday of October
- Veterans Day – November 11
- Thanksgiving Day – Fourth Thursday of November
- Christmas Day – December 25
Most U.S. businesses observe these 10 holidays, meaning the total number of business days reduces to:
- Regular Year: 261 – 10 = 251 business days
- Leap Year: 262 – 10 = 252 business days
Other countries may have different national holidays, affecting business day calculations accordingly.
Business Days in Different Industries
Different industries may define business days differently based on their operational requirements:
Banking & Financial Services
- Operate Monday to Friday, excluding federal holidays.
- Some financial institutions may observe additional holidays.
Retail & Hospitality
- Many businesses in this sector operate 7 days a week.
- Black Friday and seasonal holidays impact work schedules.
Healthcare & Emergency Services
- Operate 24/7, including weekends and holidays.
- Business days may not follow the conventional Monday-Friday structure.
How to Calculate Business Days for Your Needs
To determine business days for a project, follow these steps:
- Determine Start and End Dates – Define your timeframe.
- Subtract Weekends – Remove Saturdays and Sundays.
- Adjust for Holidays – Exclude official public holidays.
- Use Online Tools – Websites like timeanddate.com offer automatic business day calculators.
For example, if you are working on a project from January 1 to December 31, and your company observes 10 public holidays:

- Public Holidays Removed: 10
- Final Business Days: 251
Conclusion
The number of business days in a year typically falls between 250 and 260, depending on weekends and public holidays. Understanding business days helps professionals plan work schedules, meet deadlines, and calculate payroll accurately.
