Online alarm clock for 2:48 am
As you hand over the overnight watch, leave the next person a clear 2:48 am alarm for the New Zealand call, where the morning is already underway. It marks the task without making them track the time themselves, and still leaves a short window before 3:00 am to pass on the contact details and any points they need to cover.
For a New Zealand call during a quiet handover, the alarm sound should suit the room and the person taking over. A gentle tone may be enough if they are already at the desk, while a more persistent sound makes sense if they are finishing another job nearby. Set the volume before relying on it and keep this page active. If the browser session ends or the computer goes to sleep, the alarm cannot sound for the New Zealand call, so use a separate phone alarm when missing it would disrupt the handover.
Once the other person has taken responsibility for the call, reduce the chance that the dark room makes the alarm display easy to overlook. Before stepping away, switch on a low lamp near the workstation or leave a hallway light visible, rather than suddenly flooding the space at 2:48 am. Position the screen where the next person can see it from their seat, with reflections kept off the display.
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.
