How to use the online alarm clock

If daylight's still up but the day's winding down, 5:33 pm can mark the point where afternoon chores need to stop and the evening routine needs to start. Set it here, choose a sound, and it'll ring at 5:33 pm until dismissed.

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.

It's free to use, doesn't need an account, and works the same in any modern browser, but it's honestly not meant to replace your phone for anything you can't afford to sleep through. Keep the tab open and the device awake, and it'll ring reliably at the time you set. On a 24-hour clock 5:33 pm is written 17:33, and spoken aloud it's twenty-seven minutes to six in the evening. You'll also see it written 5.33 pm — a full stop instead of the colon means the same time. Whether you would say set alarm for 5:33 pm or put an alarm on for 5:33 pm, 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.
