Weekends (Saturday and Sunday) are skipped. Public holidays are not excluded.
Business days vs calendar days
A calendar day count includes every day — weekends and weekdays alike. A business day count skips Saturday and Sunday. Many legal, financial, and commercial timelines (Net 30, notice periods, SLA windows) use business days rather than calendar days.
Common business day timelines
- Net 10, Net 30, Net 60 — payment terms
- 5 business days — standard SLA response time
- 10 business days — common HR and legal notice periods
- 15 business days — shipping and delivery estimates
