Going to bed for a 6:45 am alarm

  • Asleep by 9:30 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 11:00 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 12:30 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 have only just woken up, and the scones for the village tearoom are still waiting to be started. A 6:45 am alarm gives you a clear cue to get out of bed, wash, dress and reach the kitchen before the morning gathers pace. With 7:00 am approaching, those fifteen minutes are enough to become properly alert and lay out what you need before baking begins.

Because your phone may slip into sleep mode while you do, set the alarm where you can leave the browser active and the screen awake. Check the sound level, keep the phone connected to power and run a brief test if you have not used this browser before. If the phone sleeps or the page is closed, the alarm may not sound, leaving the scones late for the tearoom opening. A separate kitchen timer can then handle each batch once you are downstairs.

An early start can make the whole morning feel available, but keep some of it unclaimed. Work backwards from the tearoom opening, allowing room after baking for cooling, arranging the counter and clearing flour from the worktop. That buffer protects the next task of the day if one tray needs longer, the oven heats slowly or the first customers appear ahead of schedule.

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 6:45 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.
