Online alarm clock for 2:34 am
Finishing seasonal fire-brigade duty at 2:34 am means closing the log, handing over anything unresolved and getting ready to leave the station. An alarm at that exact time can mark the end of your responsibilities before tired conversation stretches the handover towards 3:00 am. It also gives the incoming crew a clear point for checking keys, radios and notes with you before you head home.
A brigade handover can pull your attention into another browser tab while this alarm sits in the background. Moving away from its page need not cancel the timer, but the page still has to remain open and the phone or laptop must stay awake. If the browser page is closed or the device falls asleep, no alarm will sound, which could disrupt the brigade changeover. Checking the selected tone and volume before returning to the duty record makes that limitation less likely to catch you out.
As vehicles settle and conversations fade, a station often sounds markedly quieter by 2:34 am than it did earlier in the night. A clear tone with a sharper pitch is easier to distinguish from distant engines, radio traffic or doors closing than a soft chime. Keep the volume only as high as needed for your position in the building, especially when the incoming crew may be resting nearby.
Common questions
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.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
