Going to bed for a 9:48 am alarm

Asleep by 12:33 am — 6 full sleep cycles, about 9 hours
Asleep by 2:03 am — 5 full sleep cycles, about 7 hours
Asleep by 3:33 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 finish your NHS interview and head out at 9:48 am, the alarm can mark the moment to leave rather than let post-interview thoughts delay you. There are twelve minutes before 10:00 am, enough time to collect your belongings, check the route home and step outside without feeling rushed.

Because this reminder matters at the end of the appointment, test its sound before the interview begins. Set a brief trial alarm, confirm that it is clearly audible at your chosen volume, then reset it for 9:48 am. Keep the browser active and the phone or computer awake: if either is shut down beforehand, the interview departure alert will not sound. A quick advance check also reveals whether headphones are redirecting the signal or the volume has been left too low.

Leaving an NHS building late in the morning may mean moving from a quiet room into a busier reception, corridor or street. By 9:48 am, commuter noise may have eased, while conversations, traffic and public announcements can still mask a gentle tone. Choose a distinct sound and keep the phone somewhere it can be heard, rather than buried beneath papers or clothing.

Common questions

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.

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 9:48 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.
