How to use the online alarm clock
If you're still up rather than getting up, setting this for 1:31 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 1:31 am sharp through your speakers, so you can finally close the laptop and get some sleep.
Start by selecting a tone from the dropdown, then hit Start to lock it in. From that point the page does the counting, and it'll ring once the time is reached, but only if the tab is still open somewhere on your device. Closing it, or the browser entirely, cancels the alarm.
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 1:31 am is written 01:31, and spoken aloud it's twenty-nine minutes to two at night. Timetables and rosters may show it as 01:31, and handwritten notes as 1.31 am. Whether you would say set alarm for 1:31 am or put an alarm on for 1:31 am, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
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.
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
