Quick answer: add business days US
- US business days usually mean Monday to Friday, excluding federal holidays.
- Holiday weeks like Thanksgiving can move deadlines by several calendar days.
- State holidays and company closures may need custom holiday entries.
US federal holidays and due dates
US federal holidays are common non-working days for many organizations. When a holiday lands on a weekend, an observed day may shift to Friday or Monday. These shifts can change your due dates, so always set the correct holiday year before you exclude weekends and holidays.
State holidays and company closures
State holidays vary, and some companies observe additional closure days like inventory or end-of-year shutdowns. Use custom holidays to capture local observances so your business day calculator reflects the actual schedule.
