17 January 2030 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.
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 17 January 2030 falls on this day of the week, one working day ahead of Friday and two ahead of the weekend that follows it.
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.
