How to use the online alarm clock
An afternoon alarm at 3:05 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 3:05 pm through your laptop or desktop speakers.
Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.
A browser alarm like this one is handy when your phone's on silent, charging in another room, or you just don't want to unlock it and get pulled into notifications. The trade-off is honesty: it only rings while this tab stays open, so it's not a replacement for your phone alarm on a trip where the laptop lid might close. On a 24-hour clock 3:05 pm is written 15:05, and spoken aloud it's five past three in the afternoon. Timetables and rosters may show it as 15:05, and handwritten notes as 3.05 pm. Set an alarm for 3:05 pm, set the alarm to 3:05 pm, set my alarm for 3:05 pm — all of it lands on this page and does the same thing.
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.
