WA Business Days Calculator – Working Days in Western Australia

Calculate working days in Western Australia between two dates, or add business days to a starting date. Weekends and statewide WA public holidays for 2026 and 2027 are excluded.

General information only. This WA page applies published public holiday dates to calendar maths. It is not legal, employment or financial product advice. Check the official Western Australia list and your award or agreement. That matches ASIC’s general-information approach.
Date range: This calculator only covers dates in years that have official public holiday data on this site (currently 2026 and 2027). Dates outside that window are rejected because weekend-only maths would miss gazetted holidays. See the dated list onWA public holidays.

Holiday settings

These results use Western Australia public holidays. Other states have their own pages.

Dates must fall between 2026-01-01 and 2027-12-31. Those are the years with official holiday lists on this site. SeeAustralian public holidays.

      Western Australian holidays used in the count

      WA Labour Day is early in March, Western Australia Day is in June, and the King’s Birthday holiday is later in the year than the eastern-state June date. Those statewide weekdays, plus national weekday holidays and any listed substitute Mondays, are treated as non-working days.

      Western Australia’s list on this site is statewide rather than packed with local show days, so the default settings already match most WA workplaces. Always check the official WA publication if your industry observes an extra day.

      The working-day span includes both ends when those dates are working days. Adding business days starts after the from date. Results cannot leave 2026-01-01 to2027-12-31.

      Frequently Asked Questions

      What is a WA business day on this page?

      A Western Australia business day is a weekday that is not a statewide WA public holiday in the official 2026 and 2027 lists. Weekends are never counted. Regional or limited observances stay in the total unless you include them.

      Where do the WA holiday dates come from?

      They are the same official dates shown on the WA public holidays pages. This calculator does not keep a second copy of those lists. The government source is Western Australia.

      Can I enter dates outside 2026 and 2027?

      This calculator only covers dates in years that have official public holiday data on this site (currently 2026 and 2027). Dates outside that window are rejected because weekend-only maths would miss gazetted holidays.

      When is the WA King’s Birthday holiday for this calculator?

      Western Australia gazettes the King’s Birthday holiday on a different date from the eastern states. This page uses the weekday published on the WA public holidays list for 2026 and 2027, not the June date used in NSW or Victoria.

      Is Western Australia Day treated as a non-working day?

      Yes. Western Australia Day is a statewide public holiday in the official list, so that Monday is skipped when you count WA working days or add business days.

      Is the WA result legal or employment advice?

      No. The figure is general information for planning. It is not an interpretation of an award, not a Fair Work decision, and not financial product advice. ASIC’s general-information standard applies: confirm the gazette and your own workplace rules before you rely on a date.
