How it works
A business day is a weekday that is not a public holiday. This calculator counts business days between two dates, or steps forward from a date by a given number of business days, skipping Saturdays, Sundays and, optionally, the 11 US federal holidays.
- Choose a mode
Count days between two dates, or add business days to one date.
- Enter your dates
If the end date is before the start date, they are swapped automatically.
- Adjust what counts
Include Saturday or Sunday, or turn off the federal holiday exclusion.
About business days
In the US, a standard business day is Monday through Friday, excluding federal holidays. Most banks, government offices and corporations operate on this schedule. This calculator counts weekdays by default; use the checkboxes to include Saturday or Sunday if your business operates on those days.
US federal holidays
The US recognizes 11 federal holidays: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas Day. This calculator can automatically exclude all 11 when the checkbox is enabled, including the standard Saturday-to-Friday and Sunday-to-Monday observed-date shifts.
Common uses
- Contract deadlines, for example "within 30 business days".
- Shipping estimates and delivery windows.
- Payroll and timesheet calculations.
- Project timelines and sprint planning.
- Legal filing deadlines.
Business day definitions vary
Financial markets close on different holidays than retail stores, and definitions vary by industry and by contract. For international agreements, clarify which country's business days apply, since working days differ across countries and cultures.
Frequently asked questions
How many business days are between two dates?
Enter a start date and an end date. The calculator counts all weekdays, Monday through Friday, between them and optionally skips the 11 US federal holidays like Thanksgiving and Christmas. The result shows the business day count alongside a breakdown of business, weekend and holiday days.
What counts as a business day in the US?
In the US, a business day is typically Monday through Friday, excluding federal public holidays. The 11 federal holidays include New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. Some industries or contracts define business days differently, so always check the specific terms.
How do I calculate 30 business days from today?
Switch to Add business days to a date, set the start date to today, and enter 30. The calculator steps forward one weekday at a time, skipping holidays if the checkbox is on, and shows the exact resulting date. A rough rule of thumb is that 30 business days is about 6 calendar weeks, though holidays can add extra days.
Can I use this calculator for payroll periods or contract deadlines?
Yes. Many contracts, bank transfers and legal deadlines specify business days rather than calendar days. Enter the start date of a contract or transaction, and either compare it to a known end date or add the required number of business days to find the deadline. Toggle federal holidays on or off depending on your specific agreement.
Do weekends ever count as business days?
By default they do not, but some businesses operate Saturday as a regular workday. If your workplace treats Saturday or Sunday as a workday, check the matching box and the calculator includes it. Standard US financial and legal contexts treat only Monday through Friday as business days.
