Going to bed for a 3:11 am alarm

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

Online alarm clock for 3:11 am

As you hand the final pack-up checks to your fishing mate, a 3:11 am alarm can mark the moment to leave the water and start the drive home before commuter traffic builds. It keeps the changeover clear: one person finishes securing the rods and tackle while the other gets the ute ready. Leaving then also gives you a useful margin before 4:00 am without making the handover feel rushed.

For a fishing departure this early, the alarm is more useful when its sound has already been tested at the volume you will actually use. A quick check beforehand confirms that the selected tone is audible over quiet conversation, gear being moved and any noise near the ramp. If the browser stops running or the phone falls asleep, the 3:11 am alarm may remain silent and leave the fishing handover without its cue, so a separate phone alarm is sensible when the departure time matters.

While the fishing gear is being divided at 3:11 am, light can make the last inspection easier without ruining everyone’s night vision. A low torch or ute cabin light aimed into the tray helps reveal loose hooks, straps and bags before departure. Position it beforehand so nobody needs to search through dark gear, and avoid shining it across the water or towards another person’s eyes.

Common questions

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.

Will the alarm still ring if I close the browser tab?

No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

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.
