Online alarm clock for 11:39 pm
Being halfway through a task makes 11:39 pm easy to miss, even when the incoming guard shift is due shortly. An alarm at this exact time provides a clear break point: finish the immediate action, put down what is in hand, and move to the handover without drifting towards 12:00 am.
A handover cue is only useful when it can actually be heard. After setting 11:39 pm, check the sound level and make sure silent mode will not suppress the alert; a quick test can confirm the chosen tone is audible. Keep the browser alarm running and the equipment awake, because otherwise the guard shift may begin without any sound to pull you away from the current task.
As the late guard change approaches, sound can travel through a quiet Australian home and disturb people who are already asleep. Use a moderate volume, keep the phone or computer close to your work area, and choose a brief tone instead of a long repeating alert. At 11:39 pm, that nearby signal can be loud enough for the handover while limiting how much the rest of the household hears.
Common questions
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
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.
