A doctor's appointment, a trade callout, or a scheduled delivery booked for 10:12 am is the kind of thing worth tracking precisely rather than guessing at from the clock on the kitchen wall. This page gives the exact time left, updating every second, so there is no need to keep recalculating as the morning goes on.
Once the clock reaches 10:12 am, the countdown does not simply stop at zero — it quietly resets and starts counting towards the same time tomorrow instead. That happens on its own, with no need to refresh the page or reset anything by hand, which makes this a page worth bookmarking rather than one you only use once.
Public transport timetables in Australia are almost always printed in 24-hour time, which is exactly why 10:12 is worth having on hand even if 10:12 am 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 the countdown based on my local time?
Yes. It reads directly from your device's own clock and time zone setting, so the figure shown reflects wherever you happen to be, not a fixed time zone built into the page.
Does this work on a mobile phone?
Yes, it runs the same way in any mobile browser as it does on a desktop or laptop, with no app required and nothing to install beforehand.
Do I need to leave the tab open for it to work?
You can close it and come back any time — reopening the page simply shows the current, accurate countdown from wherever things stand at that moment, with nothing lost in between.
What is 21:30 in am or pm terms?
That is 10:12 am. Anything from 13:00 onwards in 24-hour time converts by subtracting 12, so 10:12 becomes 10:12 am — the same moment written two ways.
