Father's Day is observed on the first Sunday of September every year, shaping retail trade for the week either side of it. 6 September 2028 falls inside the same 30-day month as this observance, in the first month of the Australian spring, as warmer weather returns across the southern half of the country.
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 6 September 2028 falls on this day of the week, at the working week's midpoint, three working days deep into the week.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2028 can show a different total depending on which state's calendar applies to 6 September. Interstate businesses need to check more than one state's list before setting a national deadline.
