How to use the online alarm clock
If you're still up rather than getting up, setting this for 4:07 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 4:07 am sharp through your speakers, so you can finally close the laptop and get some sleep.
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.
Some people use this alongside a phone alarm rather than instead of it: a louder backup through laptop speakers, or a way to set a reminder without touching a phone at all. It won't survive the tab closing or the device sleeping, so for anything critical overnight, keep a second alarm running as well. On a 24-hour clock 4:07 am is written 04:07, and spoken aloud it's seven minutes past four at night. Written the Australian way that's 4.07 am, and typed in a hurry it's often 4:07am. Whether you would say set alarm for 4:07 am or put an alarm on for 4:07 am, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
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.
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
