What are business days?
Business days — also called working days or weekdays — are Monday through Friday, excluding Saturday and Sunday. They are the standard unit of time used in commerce, banking, legal proceedings, and government administration. When a contract says "payment within 5 business days," it means 5 Monday-through-Friday days, not 5 calendar days. Public and federal holidays are not automatically excluded by this calculator because they vary by country, region, state, and year. For example, the U.S. has 11 federal holidays, but individual states may observe additional ones. The U.S. Department of Labor maintains the official list of federal holidays. For a simple Monday-through-Friday count without holidays, this calculator is perfectly accurate. If you need to exclude specific holidays, subtract them manually from the result.
How to calculate business days between two dates
To count business days between two dates: list every date in the range from start to end inclusive, then count only those that fall on Monday through Friday. This calculator performs that count automatically and also shows the total calendar days and number of weekend days for context. The "Add business days" mode works in reverse: starting from a date, it advances one weekday at a time until the target count is reached, automatically skipping all Saturdays and Sundays. This is the correct method used in legal and financial contexts when a deadline is defined as "N business days from today."
Frequently asked questions
What is a business day?
A business day is any day that is not a Saturday, Sunday, or public holiday. In most countries this means Monday through Friday. Banks, courts, and government agencies typically operate on business days only. When contracts, regulations, or deadlines refer to "business days," they mean weekdays excluding weekends — and usually excluding official public holidays as well.
How many business days are in a month?
A typical month contains 20–23 business days, depending on the month and year. February in a common year has 20 business days (4 full weeks). Months with 31 days can have up to 23. To get the exact count for any specific month, enter the first and last day of that month in this calculator.
How do I add 10 business days to today?
Select "Add business days to a date," enter today's date as the start, enter 10 in the business days field, and click Calculate. The result shows the exact date 10 working days from now, skipping all Saturdays and Sundays. For example, starting on a Monday, 10 business days later is the Monday of the third week (2 calendar weeks later).
How do I calculate business days excluding holidays?
This calculator excludes weekends automatically. To exclude public holidays, first get the business day count, then subtract the number of official holidays that fall within your date range. Most countries have 8–13 public holidays per year. The U.S. has 11 federal holidays; check the Department of Labor website for the current list.
What is 5 business days from today?
Five business days from any Monday is the following Monday. From a Tuesday, it is the following Tuesday, and so on — because 5 weekdays is exactly one working week. However, if the start date is mid-week, the end date will land one week later on the same day. Use the "Add business days" mode and enter 5 to get the exact date.
How many calendar days are 30 business days?
30 business days is always 6 calendar weeks (42 days) if there are no holidays, because 5 business days per week × 6 weeks = 30. However, it can be 43–46 calendar days if the start or end of the period falls mid-week and spans additional weekend days. Use the calculator to get the precise calendar date.
Does this calculator exclude public holidays?
No — public holidays vary by country, region, and year. This calculator excludes only weekends (Saturday and Sunday). Subtract the number of relevant holidays from the result manually.
What if I need to exclude specific holidays?
After getting the result, subtract the number of public holidays that fall within the range. Most countries have 8–12 public holidays per year.
