Australia Real Due Date Calculator
Calculate when invoices, SLAs, and shipments are really due in Australia. Adjusts for national public holidays (ANZAC Day, Australia Day, Queen's Birthday, and more) plus weekends — so you see the actual business day a payment or deadline falls on.
Practical examples
Net 30 invoice adjusted for ANZAC Day
Invoice dated 26 March with Net 30. Calendar due: 25 April — ANZAC Day. Banks are closed, so the real due date shifts to Monday 28 April (if 25 April is a Friday, it moves to Monday; the next working day).
8 business-hour SLA from Friday afternoon (AEST)
Ticket logged at 3:30 PM AEST on Friday. With 9 AM-5 PM business hours, only 1.5 hours count Friday. The remaining 6.5 hours resume Monday at 9 AM. SLA deadline: Monday 3:30 PM AEST.
5 business-day delivery over Australia Day weekend
Package dispatched Friday 24 January. Saturday and Sunday skipped (2 days lost). Monday 27 January is Australia Day (substitute holiday) — also skipped. Transit resumes Tuesday. 5 business days deliver on the following Monday.
