Mother's Day is observed on the second Sunday of May every year, shaping retail and hospitality trade for the week either side of it. 11 May 2029 falls inside the same 31-day month, ten months into the financial year that began the previous July and two months short of its 30 June close.
Friday 11 May 2029 is the last working day of the standard Monday-to-Friday week, the fifth and final working day before the weekend begins. A public holiday landing on this day of the week joins directly onto the Saturday and Sunday that follow it, forming a three-day weekend without using any annual leave.
The quarter containing 11 May 2029 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.
