Going to bed for a 5:17 am alarm

  • Asleep by 8:02 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 9:32 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 11:02 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.

Online alarm clock for 5:17 am

While you wait to wheel the rubbish bins out for the collection truck, set the alarm for 5:17 am and keep an eye on the current time. That gives you a clear cue to move them from the side of the house to the kerb without putting them out earlier than needed. The collection run may be close by before the morning reaches 6:00 am, so have your shoes and keys ready.

For a rubbish-bin reminder to be useful, check whether your phone or computer is in silent mode and raise the sound to a level you will notice indoors. A quick audio check now can reveal muted media before 5:17 am arrives. The bins cue will not sound if the browser page has been closed or the device has gone to sleep, so keep the page open and the device awake until the alarm triggers.

Once the bins are beside the driveway, keep the return to bed simple: leave outdoor lights low, avoid starting another household job, and place anything you need for later where it can wait. At this early hour, a short, quiet trip outside makes it easier to preserve the sleep still available after 5:17 am. Settle back promptly rather than checking messages, especially if the truck is not yet audible in the street.

Common questions

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
