Going to bed for a 9:57 am alarm

  • Asleep by 12:42 am — 6 full sleep cycles, about 9 hours
  • Asleep by 2:12 am — 5 full sleep cycles, about 7 hours
  • Asleep by 3:42 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

As you hand the morning’s responsibilities to someone else, set the alarm for 9:57 am so leaving for your family doctor appointment does not get lost in the changeover. It gives you a clear final cue just before 10:00 am, whether you are collecting your keys, checking the address or explaining what still needs doing at home.

Your appointment depends on the alert sounding after you have finished the handover, so keep the browser active and prevent the screen from sleeping before 9:57 am. Use a charging cable if the battery is low, and leave the volume loud enough to hear from where you will be getting ready. Do not rely on this alone for the appointment: if the browser session ends or the phone goes to sleep, the chosen time may pass silently.

Leaving for a late-morning appointment can disturb anyone still working, resting or getting ready elsewhere in the house. Put your shoes, coat and keys near the door earlier, then choose an alarm tone that is audible to you without carrying through every room. At 9:57 am, silence it promptly and use the remaining moments before 10:00 am to leave calmly, rather than calling instructions across the house during the handover.

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 9:57 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.
