What our data is, where it comes from, and what it isn’t. If you only read one page here, make it this one.
Our calendar combines two things. Fixed events are computed from their own date rules, not typed in by hand — Black Friday is always the day after the fourth Thursday of November; EOFY always ends 30 June; Father’s Day is always the first Sunday in September. That means the countdowns stay correct year after year without anyone updating a spreadsheet.
Floating events — Click Frenzy, Afterpay Day, Prime Day — don’t have public date rules. We predict them from their consistent past patterns and label them Predicted until officially announced. We would rather show you an honest prediction than a confident guess.
Each category gets a twelve-month profile scored from documented retail cycles: model-changeover timing (new TV ranges land in autumn, so last year’s clear then), seasonal demand (heaters are cheapest in September because nobody wants one), the financial year, and which sale events historically discount that category. Every coloured cell you see has a written reason behind it — hover it, or read the category page.
A band is researched guidance on typical Australian street pricing for a product class — not a live quote, and not a promise. GREAT means below what that class typically sells for, so buy it. FAIR means normal shelf pricing. HIGH means you’re paying a premium, and the timing pages will tell you when that premium usually disappears.
Every band carries the date it was last reviewed. If a band hasn’t been re-checked in 120 days, we mark it as under review rather than quietly leaving a stale number on the page.
If something here is wrong — a date, a band, a claim about a product — tell us and we’ll fix it. Being corrected is cheaper than being wrong.
