Online alarm clock for 11:55 pm
You’re watching the clock while the family dinner waits for its agreed starting time. Set the alarm for 11:55 pm so you can finish a quiet task nearby without repeatedly checking the minute hand. With 12:00 am only five minutes later, the alert also gives everyone a brief moment to come to the table before midnight.
Your family dinner alert depends on the browser remaining active and the phone, tablet or computer staying awake; if either stops running beforehand, the sound may never play. Keep this page open, leave the device powered and connected, and check that its volume is audible from the dining area. A quick test alert can confirm that silent mode, headphones or a low speaker setting will not hide the signal.
While you wait late in the evening, place the screen where you can hear it without staring into its light. Lower the brightness to suit the dim room, use a warmer display setting if your device offers one, and turn the screen slightly away from the table. At 11:55 pm, a clearly audible alarm lets your eyes stay off the glowing display while you prepare for dinner.
Common questions
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.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
