How to use the online alarm clock
An alarm for 6:00 am works well as a backup for anyone who's slept through a phone alarm before: on a desk, on a laptop, wherever the tab's open. Set it, pick a sound you'll actually hear over the kettle, and it'll go off at 6:00 am sharp.
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.
Unlike a phone alarm, this one won't ring if you close the tab, put the computer to sleep, or shut the lid, so it suits a desk, a kitchen bench, or anywhere the device stays powered on and awake. It's free to use and doesn't need an account, but it's not built for unattended overnight use. On a 24-hour clock 6:00 am is written 06:00, and spoken aloud it's six o'clock in the morning. Timetables and rosters may show it as 06:00, and handwritten notes as 6.00 am. Whether you would say set alarm for 6:00 am or put an alarm on for 6:00 am, the steps are the same: pick a sound, press Start, leave the tab open.
Common questions
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.
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
