Online alarm clock for 3:45 am
Getting ready before the American share market opens gives you a quiet window to check your watchlist, notes and internet connection. An alarm set for 3:45 am marks the point to finish those checks before 4:00 am, without relying on a last-minute glance at the clock.
Your household and surroundings should guide the alarm tone. A softer sound may suit a shared bedroom, while a more persistent tone can help when the phone sits across the room or overnight noise masks a gentle alert. The chosen volume can be tested now, while there is still time to change it. Keep a separate backup alarm, because if this browser alarm stops running, the American share market opening could pass without any sound.
Preparation at this hour is easier with a dim, warm-toned screen rather than a bright display in a dark room. The watchlist and essential notes can be arranged beforehand so there is less scrolling at 3:45 am. Once the alarm sounds, using a low brightness setting and switching off unneeded notifications keeps the screen focused on the market information already selected.
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.
