How to use the online alarm clock
An afternoon alarm at 4:59 pm works well for anyone who's ducked away for a quick rest and doesn't trust themselves to wake up on their own. Set the time, choose a tone, and leave the tab open. It'll ring at 4:59 pm through your laptop or desktop speakers.
Select a sound, hit Start, and that's the whole setup. The countdown runs inside this browser tab rather than on your device's operating system, so it needs to remain open, on a phone or laptop, until the alarm actually goes off.
Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 4:59 pm is written 16:59, and spoken aloud it's one minutes to five in the evening. You'll also see it written 4.59 pm — a full stop instead of the colon means the same time. Setting the alarm to 4:59 pm tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
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.
