Going to bed for a 9:09 am alarm

Asleep by 11:54 pm — 6 full sleep cycles, about 9 hours
Asleep by 1:24 am — 5 full sleep cycles, about 7 hours
Asleep by 2:54 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

While you wait to meet the inspector at your rented home, set the alarm for 9:09 am and keep an eye on the remaining morning. It gives you a clear marker for checking the entrance, finding the tenancy papers and making sure your phone is within reach. With 10:00 am still ahead, the appointment does not have to blur into the rest of the hour.

During the wait, this page may slip behind messages, emails or another browser page. The timer should continue there, but browser power-saving rules can sometimes delay activity that is not in view, so return here shortly before 9:09 am and check that sound is allowed. If you close the page or let the computer or phone go to sleep, the alarm cannot warn you when the inspector is due; keep it open and the device awake until the sound plays.

As the inspector’s arrival approaches, notice which sounds are masking quieter cues: traffic may be building, neighbours may be leaving, and a communal door can become busier around this point in the morning. Raise the alarm volume enough to be heard over that background, but keep the phone nearby instead of relying on a loud signal from another room. That also leaves you able to hear the buzzer or a knock at 9:09 am.

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.
