Online alarm clock for 11:33 pm
Handing the shift to someone else at 11:33 pm gives you a brief window to confirm who will handle the London call while their working morning is underway. Set the alarm before you finish the handover, and note the call time somewhere visible so the next person has the same details. With 12:00 am approaching, the signal can also mark a final check rather than leaving responsibility unclear at midnight.
Your London contact may be speaking from a busy office while you are surrounded by late-night household noise, traffic or a television. Choose a signal volume you can clearly hear from where you will be waiting, then test it against that background sound. If the browser stops running or the laptop sleeps, there will be no alarm for the London call, so use another alert when missing the handover would leave nobody available.
Once the handover is settled, allow for the trip home instead of assuming Australian roads will be empty late in the evening. Roadworks, reduced overnight public transport and longer waits for a rideshare can change the journey. Check the expected travel time before 11:33 pm, add a small buffer, and place the alarm early enough to finish the call details without rushing to leave.
Common questions
Can I use this on my phone instead of a laptop?
Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
Can I set more than one alarm at a time?
This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
