Labour Day falls on the first Monday of May in Queensland and the Northern Territory, the only two jurisdictions that mark the holiday on this date. 22 May 2027 falls inside May in every other state and territory without any public holiday attached to it at all, running as an entirely ordinary working month in New South Wales, Victoria, South Australia, Western Australia, Tasmania and the ACT.
Any deadline or bill payment due on Saturday 22 May 2027 moves to the following Monday under standard business-day rules, since Saturday is not a working day for the Monday-to-Friday workforce this page counts by default. Shift-based industries follow their own separate rostering rules instead of this convention.
The quarter containing 22 May 2027 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
