Going to bed for a 7:38 am alarm

  • Asleep by 10:23 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 11:53 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 1:23 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

Still half-awake at 7:38 am, you can use this alarm as the point to sit up and check the Met Office ice warning before anything else begins. That leaves the forecast in view early enough to reconsider the walk to the station, the school run or the first drive of the day before 8:00 am. The alert marks a clear boundary between waking and making plans.

Your warning check could easily be missed if the alarm sound has quietly been routed to headphones left beside the bed. The selected tone needs an audible route through the phone or computer speakers, with the volume high enough to notice from where you are resting. If this page is closed or the device goes to sleep, the Met Office warning may go unchecked because the browser alarm cannot sound. A separate backup alarm is sensible when icy conditions could affect the morning.

For an early forecast check in a dim room, a suddenly bright screen can feel harsh on sleepy eyes. Keeping the display at a low, readable brightness gives you enough light to identify the warning area without flooding the room. Once the details are clear, setting the screen face down again reduces the temptation to drift into messages before the day has properly started.

Common questions

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 7:38 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.

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
