December is the busiest trading month of the year for retail and hospitality, with Christmas shopping and the summer sales season running through most of the 31-day month. December 2030 closes the financial year's second quarter, which runs from October to December, and the fourth calendar quarter of 2030, both quarters closing on the very same date, 31 December. Summer begins on 1 December, the first day of December.
December closes both the fourth calendar quarter of 2030 and the financial year's second quarter, which runs from October to December, on the same date of 31 December. December 2030 also closes the 365-day calendar year itself, resetting every quarterly and annual reporting cycle at once for businesses that report against the calendar year. Christmas Day falls on 25 December and Boxing Day on 26 December every year, the two fixed holidays of December.
The shift from December into January carries the country from one calendar year into the next without pause, since the school summer holidays and daylight saving both continue unbroken across the change of year. December 2030 hands over directly to a new twelve-month cycle that begins on 1 January with its own run of public holidays already fixed. Summer begins on 1 December, the first day of December.
