Online alarm clock for 3:47 am
You’re getting ready at 3:47 am so the US sharemarket opening does not catch you still sorting charts, notes or account details. Set this alarm as an early checkpoint, leaving the 13 minutes before 4:00 am for a final review and a quiet drink while the rest of the Australian household is likely asleep.
Your market preparation can come unstuck if the alert is muted, so check the sound setting and raise the volume enough to hear it without waking everyone nearby. A short test alert can confirm that silent mode will not suppress the signal. The US sharemarket opening could be missed if you end the browser session or let the computer sleep, because this alarm then cannot sound; use a separate alarm clock or phone alert as backup when the timing matters.
Late-night market work is easier when the room lighting is arranged before 3:47 am. Place a small lamp beside or behind the screen, switch off harsh overhead lighting, and close blinds if outside reflections fall across your display. Preparing those settings earlier means you can sit down quietly, read figures without screen glare, and keep the house dark beyond your immediate workspace as 4:00 am approaches.
Common questions
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.
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.
