Going to bed for a 6:11 am alarm

  • Asleep by 8:56 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 10:26 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 11:56 pm — 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

While you watch the clock and wait to open the public pool for its early session, a 6:11 am alarm marks the exact moment to act. It keeps your attention on the opening rather than on repeated clock checks, with 49 minutes still available before 7:00 am for the first swimmers to arrive and the morning routine to settle.

A quiet pool entrance can become surprisingly noisy once ventilation, pumps and early arrivals fill the space. Set the alarm volume high enough to remain distinct from that background, and choose a tone that will not blend into machinery or conversation. A brief sound check shows whether it carries from wherever you are waiting. If you close the browser page or allow the phone or laptop to sleep, the pool may remain locked because the 6:11 am alarm cannot sound.

Before the early session, surrounding noise often changes quickly: an empty building may be calm at first, then echo with staff activity and people gathering near reception. You can keep the phone or laptop nearby and away from running water, with its speaker facing into the room rather than towards a wall. That position gives the signal a clearer path as 6:11 am approaches.

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.
