How to use the online alarm clock
Between three and six, most households are managing some kind of handover: work to home, school to training. An alarm for 4:03 pm helps keep it on schedule. Set it here and it'll ring right on 4:03 pm until you tell it to stop.
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.
This works well as a second alarm, one that isn't tangled up with phone notifications, do-not-disturb settings, or low battery. It genuinely won't ring if the tab gets closed or the device goes to sleep, so treat it as a backup or a work-desk tool rather than the only alarm for something important. On a 24-hour clock 4:03 pm is written 16:03, and spoken aloud it's three minutes past four in the afternoon. You'll also see it written 4.03 pm — a full stop instead of the colon means the same time. Set an alarm for 4:03 pm, set the alarm to 4:03 pm, set my alarm for 4:03 pm — all of it lands on this page and does the same thing.
Common questions
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.
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
Can I use this on my phone instead of a laptop?
Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
Can I set more than one alarm at a time?
This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
