Going to bed for a 8:17 am alarm

  • Asleep by 11:02 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 12:32 am — 5 full sleep cycles, about 7 hours
  • Asleep by 2:02 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.

Online alarm clock for 8:17 am

As you hand the run to another driver, an 8:17 am alarm can mark the moment they need to leave before a road train blocks the route. It gives you a clear handover point while there is still time to pass on the vehicle details, keys and any local road information. The departure should then be under way well before 9:00 am.

For a road handover, the alarm tone needs to suit the surroundings as well as the person taking over. A softer sound may be enough in a quiet office or parked cab, while a more insistent tone is easier to notice around engines and conversation. Check that the volume matches that choice. If you close the browser page or let your phone or laptop sleep, the alarm will not sound, which could make the road departure late.

Before the replacement driver heads out, the cab temperature deserves a quick check alongside the route notes. At 8:17 am, Australian heat can already make a parked vehicle uncomfortable, yet strong air conditioning may leave the next driver reaching for controls instead of settling in. A moderate setting during the handover keeps the changeover practical and avoids wasting those early minutes adjusting the cabin.

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.
