Tax returns can be lodged from 1 July, opening a four-month window that runs to the 31 October self-lodgement deadline. 14 July 2030 falls inside the first month of both that window and the financial year that began on 1 July, with most of the tax season still ahead of it.
Sunday 14 July 2030 is a weekend day under the standard Monday-to-Friday working pattern and does not count toward the working-day total shown above, the last day of the weekend before the working week resumes on Monday morning across most Australian workplaces and schools.
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.
