How to use the online alarm clock
Getting out the door for the school run or the commute into the city gets easier when 10:46 am is locked in properly. Choose a sound, hit start, and this browser alarm will ring at 10:46 am whether you're upstairs making lunches or still half asleep. Just keep the tab open so it has a chance to go off.
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.
The advantage of a browser alarm is volume and reliability at a desk: laptop speakers are often louder and easier to hear across a room than a phone left in a bag. The catch is that it depends entirely on the tab staying open; if the browser closes or the laptop sleeps, the alarm won't fire. On a 24-hour clock 10:46 am is written 10:46, and spoken aloud it's fourteen minutes to eleven in the morning. You'll also see it written 10.46 am — a full stop instead of the colon means the same time. Setting the alarm to 10:46 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
Common questions
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.
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.
