Dinner is one of the more reliable fixed points in a lot of Australian households, and if 8:19 pm is when it actually lands on the table, a live countdown makes the last stretch of the day easier to plan around. The number updates every second, so there is never any need to recalculate by hand.
The numbers shown here run on your own device's clock, checking the time continuously and recalculating the gap to 8:19 pm every second. There is nothing to press and nothing to configure — the countdown is already running the moment the page finishes loading, and it keeps updating for as long as you are looking at it.
Public transport timetables in Australia are almost always printed in 24-hour time, which is exactly why 20:19 is worth having on hand even if 8:19 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
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.
Why does the countdown look different on two devices checked at once?
That usually means the two clocks are not perfectly in sync, or one device has not adjusted for a time zone or daylight saving change. The countdown itself always follows whatever clock it is reading from.
Is there a way to make the countdown count towards a different time?
This particular page is fixed to one target time. Checking a different one just means visiting the matching page built for that specific time instead.
