Father's Day is observed on the first Sunday of September every year, shaping retail trade for the week either side of it. 2 September 2027 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 Thursday sits one day short of the weekend, and workers commonly take the Friday after it as annual leave to turn a single day off into a four-day break. Thursday 2 September 2027 falls on this day of the week, one working day ahead of Friday and two ahead of the weekend that follows it.
Contracts and legal deadlines that specify calendar days count every day from 2 September 2027 including weekends and public holidays, while deadlines specified in working or business days count only the days this page includes in its working-day total. The difference between the two conventions can shift a deadline by several days once weekends and holidays are counted.
