Online alarm clock for 2:57 am
Before you hand the overnight duty to someone else, set the 2:57 am alarm to mark the moment for your call to Perth, where it is three hours earlier. That gives you a clear cue to finish the handover, check the details your replacement needs and be ready to ring as 3:00 am arrives.
Because the call sits at the end of a shift, the alarm needs to be audible even if your attention has moved to notes or a conversation. Check that silent mode is off and set the volume high enough for the room without disturbing everyone nearby. If the browser tab is closed or the device goes to sleep, no alarm will sound, so the Perth call can be missed. Leaving the screen active and doing a quick sound check beforehand avoids relying on a muted alert.
Once the handover notes are ready, a glass of water or a small, simple snack fits the short wait before 2:57 am. A full meal or another strong coffee can wait until after the call, when you are no longer juggling the clock and another person’s briefing. Keeping the drink beside you also means there is no last-minute trip to the kitchen just as 3:00 am approaches.
Common questions
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
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.
