4 January 2026 (Sunday)

4 January 2026 sits in the middle of the Australian summer, when the southern states run hot and dry with bushfire risk at its seasonal peak. The tropical north sits inside its wet season, part of the cyclone season that runs from November through to April every year. Daylight saving stays in effect in New South Wales, Victoria, South Australia, Tasmania and the ACT for the whole of January, keeping evenings light well past eight in the evening across those five states.

Any deadline or bill payment due on Sunday 4 January 2026 moves to the following Monday under standard business-day rules, since Sunday sits outside the working week this page counts by default. This convention applies consistently across contracts, invoices and statutory deadlines throughout Australia, regardless of which state or territory is involved.

The hours and minutes shown in the countdown to 4 January 2026 are calculated against the clock and time zone set on the device displaying this page, and the countdown reaches zero at midnight local to that device. Two people in different time zones will see slightly different figures at the exact same moment, each reflecting their own local midnight.
