Going to bed for a 9:31 am alarm

Asleep by 12:16 am — 6 full sleep cycles, about 9 hours
Asleep by 1:46 am — 5 full sleep cycles, about 7 hours
Asleep by 3:16 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 the first job is making sure you are ready for your tour of the Houses of Parliament. Set the alarm for 9:31 am before getting out of bed, then use the time before 10:00 am to wash, dress and gather anything you planned to take. That gives the morning a clear starting point without turning every small task into a rush.

While you check your route or booking details, the alarm page may slip behind another page in the browser. It should continue counting there, so you can get on with preparing rather than keeping it visible. Leave the browser running and the computer awake, however: otherwise the Parliament tour alarm cannot make a sound when 9:31 am arrives. Check that the volume is audible before moving away from the screen.

A Parliament visit can affect everyone sharing the morning routine, especially if 9:31 am is earlier than others need to stir. Choose a moderate volume and keep the computer close to you, rather than letting the alarm carry through the house. Put clothes, keys and your travel essentials together quietly beforehand, so the signal marks your departure routine without becoming everybody else’s wake-up call.

Common questions

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.

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.
