Online alarm clock for 4:00 am
You’re waking at 4:00 am with the US sharemarket about to open, so the first task is simply getting your eyes open and checking what happened overnight. An alarm at that round hour gives you a clear starting point before charts, announcements or watchlists demand attention. Keep the phone within reach so you can silence the sound without fumbling around in the dark.
For this 4:00 am market wake-up, the main risk is relying on hardware that slips into sleep before the alarm is due. Set the sound and volume while you are still awake, then leave the browser running and keep the device powered and alert. If the browser stops running or the device sleeps, the market opening may pass without an alarm sounding. A plugged-in phone or laptop with sleep disabled for the night makes the setup more dependable, while a separate backup alarm covers an unexpected restart or flat battery.
Because the house is likely quiet at 4:00 am, a sharp alarm can wake everyone long before their own morning begins. Place the device close to your side of the bed, choose a moderate tone, and use vibration if the surface will not amplify it through the room. Preparing headphones, water and anything needed for the sharemarket beforehand also reduces drawers, doors and footsteps once you are up.
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.
