By default we count Monday through Friday as working days and remove any public holiday that falls on those weekdays. A bank holiday that lands on a Saturday is not subtracted again, because it was never a working day to begin with; this is how UK statutory holiday counting works and how most European payroll systems treat the calendar. A bank holiday that falls on a Sunday in the United States is technically observed on the following Monday, and Nager.Date already encodes the observed dates, so the result you see already reflects the substitute day.
We use the public Nager.Date dataset, which collates official holidays for around 110 countries and is licensed CC-BY. It updates when governments change their schedules, which happens more often than you would think. Country-specific religious holidays and regional holidays are included where Nager.Date marks them as national. If you need a per-state or per-county breakdown, the dataset has a granular view we will surface in a future update. For a quick look at this year's holidays in one place, see the US holidays page or jump back to days between dates for a calendar-day breakdown.
Procurement and finance teams use the working-day count for purchase order lead times and invoice terms ("net 30 working days" means something different to "net 30 days"). HR uses it for statutory and contractual leave. Project managers use it for capacity planning when a delivery date crosses a long weekend or a national holiday. Solicitors use it for service of process deadlines that are stated in clear days. The math is the same whichever industry you are in: count weekdays, subtract weekday holidays, and you have your answer.
