Going to bed for a 11:05 am alarm

Asleep by 1:50 am — 6 full sleep cycles, about 9 hours
Asleep by 3:20 am — 5 full sleep cycles, about 7 hours
Asleep by 4:50 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 may be halfway through sorting the books for the mobile library when the 11:05 am alarm pulls you away from the job. That alert gives you a clear point to stop checking titles, pack the returns and get ready to leave. With 12:00 pm approaching, there is still time to finish the essential bits without letting the whole morning disappear into one more shelf or bag.

Your library return depends on hearing the signal, so the browser needs to remain active until it sounds. A phone or laptop that falls asleep before 11:05 am cannot play the alarm, and closing the tab also means the books may miss their scheduled mobile-library stop. Check the power settings beforehand, keep the screen awake and set the volume high enough to carry from wherever you are sorting.

Once the books are packed, allow for the journey rather than treating 11:05 am as your departure time. Late-morning traffic can build around school streets, town centres and roadworks, while a mobile library may stay at a village stop only briefly. Put the bags beside the door, check the route before the alarm sounds and leave a small margin for parking and carrying the returns over.

Common questions

What happens if my laptop goes to sleep before 11:05 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.
