Prime-time television across Australian free-to-air channels tends to build towards a fairly fixed slot each evening, and for a lot of households 6:31 pm is the point where the good stuff actually starts. This page counts down to it precisely, right down to the second, rather than leaving you to guess from the clock on the wall.
Because the countdown reads straight from your device's own clock, its accuracy depends on that clock being set correctly, including the right time zone. Most phones and computers handle this automatically, so in practice the figure shown lines up with whatever time your device already displays.
Public transport timetables in Australia are almost always printed in 24-hour time, which is exactly why 18:31 is worth having on hand even if 6:31 pm is the version that comes to mind first. Matching the two formats against each other takes the guesswork out of reading a printed timetable correctly.
Common questions
Is anything installed on my device to run this?
No. Nothing downloads or installs — the countdown runs entirely within the page in your browser, and closing it removes it completely with nothing left behind.
Why does the number change slightly every time I check?
Because it is a live countdown rather than a fixed figure, it updates every second, so the exact hours, minutes, and seconds remaining will always be a little lower than the last time you looked.
Can I use this to time something happening tomorrow instead of today?
The countdown always points to the next time that moment occurs, so if it has already passed for today, it is already counting down to tomorrow's occurrence without any adjustment needed.
Does daylight saving affect the countdown?
Yes, because it reads from your device's own clock, any daylight saving change your device applies automatically is reflected in the countdown without any extra step on your part.
