How to use the online alarm clock
Whether 10:27 pm marks the start of a night shift or the point you've promised yourself you'll finally stop for the day, this tool rings at 10:27 pm straight from your browser. No sign-up needed, just a tab left open until it fires.
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.
A browser alarm like this one is handy when your phone's on silent, charging in another room, or you just don't want to unlock it and get pulled into notifications. The trade-off is honesty: it only rings while this tab stays open, so it's not a replacement for your phone alarm on a trip where the laptop lid might close. On a 24-hour clock 10:27 pm is written 22:27, and spoken aloud it's twenty-seven minutes past ten at night. Written the Australian way that's 10.27 pm, and typed in a hurry it's often 10:27pm. If you need it loud, turn the system volume up before you start: the alarm plays at whatever the device is set to.
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.
