Going to bed for a 8:46 am alarm

  • Asleep by 11:31 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 1:01 am — 5 full sleep cycles, about 7 hours
  • Asleep by 2:31 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 8:46 am

Halfway through setting out the beach flags, you need an 8:46 am alarm to pull you away from the job and mark the changeover. It leaves enough time to finish the flag you are handling, check the swimming area and be ready for the next lifeguard before 9:00 am, without repeatedly glancing at the clock.

Because the beach setup can take you away from your phone, leave this alarm running where you can hear it and keep the screen awake. If the browser is closed or the phone falls asleep, the alarm for the lifeguard change may not sound, so it should not be the only signal relied on for the handover. Check the volume before returning to the flags, and avoid silencing the phone along with other early-morning notifications.

An early start on an Australian beach may have followed a shorter night than usual, especially after travel or a late finish. Once the 8:46 am handover is complete, note how much sleep remains available before the next commitment instead of letting small jobs consume the break. A defined rest window, with another reliable alarm if needed, makes that remaining sleep easier to protect.

Common questions

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

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.
