Going to bed for a 11:09 am alarm

Asleep by 1:54 am — 6 full sleep cycles, about 9 hours
Asleep by 3:24 am — 5 full sleep cycles, about 7 hours
Asleep by 4:54 am — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

How to use the online alarm clock

You are halfway through something when the 11:09 am alarm tells you to break away and prepare for your magistrates’ court hearing. That interruption leaves enough morning to gather your papers, check the courtroom details and shift your attention from the task in front of you. With 12:00 pm approaching, the alarm marks a practical point for stopping rather than letting the current job run into your departure time.

While you organise what you need for the magistrates’ court, keep the alarm page visible where possible. Browsers sometimes reduce activity on pages left in the background, which may affect when their sounds play. Check that the volume is audible and leave the browser running. Do not treat this alarm as your sole prompt: if the browser stops operating, you could miss the magistrates’ court hearing because no alert will sound.

Getting to the magistrates’ court can take longer as the morning moves towards lunchtime, particularly around a town centre with busy junctions, limited parking or a walk from the station. Work backwards from the required arrival time, allow for security at the entrance, and add a small margin for the route. At 11:09 am, checking live travel conditions before leaving helps turn the alarm into a realistic departure cue.

Common questions

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 11:09 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
