Going to bed for a 10:31 am alarm

Asleep by 1:16 am — 6 full sleep cycles, about 9 hours
Asleep by 2:46 am — 5 full sleep cycles, about 7 hours
Asleep by 4:16 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 collecting your prescription from the GP surgery is still the first job of the day. Set the alarm for 10:31 am so you have a clear point to get out of bed, dress and check the surgery’s collection hours. That leaves a useful stretch before 11:00 am for finding your keys, NHS details and anything else you need to take.

Your prescription trip determines whether the alarm should sound gently or insistently. A softer tone may suit a quiet start if you are already awake and simply need a cue to move; a more persistent sound makes sense if you might drift off again. Check the volume before settling back. For the prescription collection, this alarm is dependable only while its page remains running and your phone stays awake; if either stops, there will be no sound.

Leaving for the GP surgery during the later morning may affect everyone else at home, especially if doors, showers or shared hallways carry noise. Put clothes and keys together before 10:31 am, then keep the alarm volume just high enough to reach you without filling the house. If someone else is sleeping, place the phone close by and use vibration alongside a restrained tone.

Common questions

What happens if my laptop goes to sleep before 10:31 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.

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.
