How to use the online alarm clock
Three in the morning has its own kind of silence, and an alarm for 2:18 am breaks it on purpose. Whether you're catching a pre-dawn flight or grabbing a short nap before a long haul, this tool rings at 2:18 am through your browser so you're not relying on a phone across the room.
Using it is simple: pick a ringtone from the list, press Start, and leave this tab open in your browser. The alarm runs entirely on this page, so closing the browser will stop it from going off. Come back a minute early if you're not sure you trust it yet.
Compared to a phone, this alarm has one job and nothing else competing for attention — no messages, no app switching. It's free and doesn't ask for sign-up, but it only works while the tab is open and the device stays awake, so it suits daytime use at a desk better than an overnight bedroom alarm. On a 24-hour clock 2:18 am is written 02:18, and spoken aloud it's eighteen minutes past two at night. Timetables and rosters may show it as 02:18, and handwritten notes as 2.18 am. Whether you would say set alarm for 2:18 am or put an alarm on for 2:18 am, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
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.
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.
