Quick answer: business days between dates US
- US business days usually mean Monday to Friday, excluding federal holidays.
- State holidays and company closures need custom entries beyond the preset.
- Holiday years must match your date range to keep counts correct.
Federal holidays and why they matter
Federal holidays like Thanksgiving, Independence Day, and New Year’s Day are widely observed. When excluded, they reduce business day counts and can move deadlines into the following week. Observed dates that shift to Friday or Monday also affect totals.
State and company differences
State holidays and company shutdowns are not in the federal preset. Add custom holidays for state observances, inventory freezes, or end-of-year breaks so your workday total reflects your actual calendar.
Worked examples
Example A: Thanksgiving week
Range spans Thu–Fri holiday and weekend.
Result: drops two business days when excluded.
Example B: New Year crossover
Range: Dec 28 to Jan 4, include both.
Result: Jan 1 exclusion drops one day.
Example C: Add state closure
Add a state holiday Monday to the preset.
Result: one more day removed from the total.
