Daylight saving ends on the first Sunday of April in New South Wales, Victoria, South Australia, Tasmania and the ACT, putting the clocks back an hour. 4 April 2027 falls in the month where those five states move off daylight time, while Queensland, Western Australia and the Northern Territory keep the same clock they have run all year without any change.
Retail, hospitality, healthcare and emergency services rosters regularly schedule staff to work on Sundays as part of standard shift patterns that do not follow the Monday-to-Friday week. 4 April 2027 falls on Sunday, a working day for these shift-based industries even though it sits outside the standard working-day count above.
Contracts and legal deadlines that specify calendar days count every day from 4 April 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.
