How to use the online alarm clock
Between dinner and bed, 8:31 pm is a common time to want a reminder that doesn't rely on remembering to check the clock yourself. Set this for 8:31 pm, pick a tone, and it'll ring through your browser for as long as the tab stays open.
Choose a sound before you press Start — something like a chime or a classic bell tends to work better than anything too gentle. Once it's running, the countdown happens right here in the browser, which means the tab needs to stay open in the background rather than being closed.
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 8:31 pm is written 20:31, and spoken aloud it's twenty-nine minutes to nine at night. Timetables and rosters may show it as 20:31, and handwritten notes as 8.31 pm. Setting the alarm to 8:31 pm tomorrow morning works the same way: if the time has gone for today, the count runs through to it.
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.
