Online alarm clock for 2:24 am
Pause your rounds at 2:24 am only long enough to set an alarm for the security shift handover. You may be checking gates, logging an incident or watching a camera feed, so the alert gives you a clear point to break away without losing your place. It also leaves a practical buffer before the 3:00 am handover for finishing notes and briefing the next guard.
Because closing the browser stops this alarm, the security shift handover could pass without any sound; likewise, a sleeping phone or laptop may not produce the alert. Keep the alarm page open, leave the device awake and set the volume high enough to carry across the control room. If your duties take you beyond hearing range, use the device’s built-in alarm as a backup for 2:24 am.
During an Australian summer night, a cooled control room can feel comfortable while the outside patrol area remains hot and humid. Before stepping away for the handover, place water and any required keys beside your notes, then check that the air conditioner is not masking the alarm tone. A short walk between indoor and outdoor posts can also make the temperature change noticeable, so allow a moment to settle before giving a precise verbal briefing.
Common questions
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.
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
