About Business Days
📅 What Counts as a Business Day
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.
🏛️ Federal Holidays
The US recognizes 11 federal holidays: New Year’s Day, MLK Day, Presidents’ Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas.
This calculator can automatically exclude all 11 US federal holidays when the checkbox is enabled.
💡 Common Uses
- Contract deadlines (e.g., “within 30 business days”)
- Shipping estimates and delivery windows
- Payroll and timesheet calculations
- Project timelines and sprint planning
- PTO accrual and vacation planning
- Legal filing deadlines
⚠️ Important Considerations
Business day definitions vary by industry. Financial markets close on different holidays than retail stores. Always confirm the specific business day rules for your situation.
For international contracts, clarify which country’s business days apply — working days differ across countries and cultures.
