Type	What it counts	Common use
Calendar days	Every day, including weekends & holidays	Visas, invoices, statutory periods, leases
Business days	Mon–Fri only, excluding public holidays	Settlement, court deadlines, shipping estimates

For business-day calculations including Australian public holidays by state, see the Business Days Calculator.
