Going to bed for a 11:16 am alarm

  • Asleep by 2:01 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:31 am — 5 full sleep cycles, about 7 hours
  • Asleep by 5:01 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 11:16 am

As you hand the library shift to the next staff member, an alarm for 11:16 am can mark the moment to finish your notes and explain anything still pending. It also leaves a clear checkpoint before the doors open to readers. With 12:00 pm approaching, the handover can cover desk duties, returns and any bookings that need attention.

Readers gathering near the entrance can create enough background noise to bury a quiet signal, so the selected alarm tone needs to be clearly audible at the circulation desk. The volume can be checked beforehand without relying on vibration or a subtle notification. If the browser page is closed or the phone or laptop goes to sleep, the alarm cannot sound, leaving the library shift without its planned handover cue.

Before the next staff member takes over, consider where the device will sit during the late morning. Australian heat outside may contrast sharply with strong air conditioning indoors, and a phone tucked into a bag or jacket can become difficult to hear. A spot near the desk, away from an air-conditioning vent and the busiest return trolley, keeps the 11:16 am signal closer to the person who needs it.

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.
