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. 8 May 2030 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.
A public holiday landing on a Wednesday sits in the middle of its working week rather than beside a weekend, so it does not create a long weekend on its own. Wednesday 8 May 2030 falls on this day of the week, at the working week's midpoint, three working days deep into the week.
2030 has 365 days on the calendar. Leap years add a single extra day to February, giving those years 366 days instead of 365 and shifting the day-of-year number for every date from March onward by one compared with an ordinary year. This is the only irregularity in the length of the Australian calendar year.
