Online alarm clock for 11:38 pm

You have just woken at 11:38 pm and the children’s bedtime routine has not begun, so the first job is to get everyone settled without turning the house upside down. An alarm for this exact time can mark the moment to start pyjamas, teeth and a final drink of water. With 12:00 am approaching, a calm sequence now can keep the schedule recognisable even after a late disruption.

For a bedtime cue, set the signal loud enough to be heard over the television, air conditioner or conversation elsewhere in the house, then test it from the room where you will be. A phone tucked beneath bedding or left beside a noisy fan may make the alert easy to miss. Keep the alarm page running and the phone awake, because otherwise the children’s bedtime signal will not sound when you need it.

Once the bedtime routine is moving, keep the screen dim and avoid holding it close to your eyes while checking the time. At this late hour, use the alarm as the cue, then place the phone face down where its glow will not light the room. If you need to check progress before midnight, a brief glance is enough; the remaining steps can follow the familiar household routine.

Common questions

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.

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
