South Australia Business Day Calculator

Last reviewed: May 19, 2026 · Holiday data: June 24, 2026

Calculate business days in South Australia with its own public holidays. South Australia shares the Monday to Friday working week and the Saturday and Sunday weekend with the rest of Australia, but its public holiday calendar is different, so due dates and deadlines can land differently from the national count.

How South Australia differs from the national Australian holidays

South Australia follows the national Australian public holidays and adds four of its own. It takes Adelaide Cup Day on the second Monday of March, observes Easter Saturday and Easter Sunday (Easter Sunday became a public holiday in 2024 under the Public Holidays Act 2023), and holds Labour Day on the first Monday of October. The King's Birthday stays on the national June date, and South Australia does not move Anzac Day when 25 April falls on a weekend. The working week is Monday to Friday with a Saturday and Sunday weekend, so the public holiday set is what changes the count.

Worked example

Adding 2 business days to Friday, March 6, 2026 using South Australia's public holidays lands on Wednesday, March 11, 2026. With the national Australian public holidays, the same calculation lands on Tuesday, March 10, 2026: the gap comes from South Australia's own calendar.
