How to use the online alarm clock
Getting the kids into a bedtime routine often comes down to one reliable alarm at 7:51 pm that isn't ignored the way a phone reminder gets swiped away. Set it here and it'll ring at 7:51 pm through your speakers until someone turns it off.
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 7:51 pm is written 19:51, and spoken aloud it's nine minutes to eight in the evening. Timetables and rosters may show it as 19:51, and handwritten notes as 7.51 pm. Whether you would say set alarm for 7:51 pm or put an alarm on for 7:51 pm, 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.
