Business Days vs Working Days
While these terms are often used interchangeably, there's a subtle but important difference:
- Working Days: Typically Monday-Friday, excluding weekends only
- Business Days: Monday-Friday excluding both weekends AND public holidays
For critical deadlines, shipping estimates, and legal contracts, you usually need business days that account for holidays when businesses are closed.

- Select which days are weekends (default: Saturday & Sunday)
- Add any holidays that fall within your date range
- See the accurate business day count instantly
