How to use the online alarm clock

If you're still up rather than getting up, setting this for 1:12 am gives you a hard stop. Daylight saving time or not, the sun won't be up yet. It works the same regardless of the season, ringing at 1:12 am sharp through your speakers, so you can finally close the laptop and get some sleep.

There's a short list of sounds to choose from before you press Start — pick one that suits how deep a sleeper you are. Once it's set, the page keeps time in the background of your browser, and it'll sound at the moment you selected, provided the tab hasn't been closed.

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 1:12 am is written 01:12, and spoken aloud it's twelve minutes past one at night. Timetables and rosters may show it as 01:12, and handwritten notes as 1.12 am. Whether you would say set alarm for 1:12 am or put an alarm on for 1:12 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.
