Going to bed for a 11:29 am alarm

  • Asleep by 2:14 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:44 am — 5 full sleep cycles, about 7 hours
  • Asleep by 5:14 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 11:29 am

As you hand the apartment inspection over to your partner or another family member, set the 11:29 am alarm to mark the changeover. It gives you a clear point for passing across the agent’s details, the address and any questions still unanswered. With 12:00 pm approaching, the other person then has time to review the list before the late-morning appointment continues.

While the inspection notes or property photos are open, this alarm page may sit behind another browser tab. It should keep counting while you move between pages, although browser power-saving settings can sometimes delay a background alert. Keep the browser page running and the phone awake enough to play sound. For the apartment inspection, the alarm cannot provide a reliable handover cue after its page has been closed or the phone has fallen asleep.

Before leaving the inspection or swapping places at 11:29 am, a drink of water is practical if the morning has involved walking through several rooms or travelling across town. Save a full lunch for after the remaining questions and photos have been handed across; eating now can distract from a quick final check. A small snack is easier to manage if the changeover runs towards 12:00 pm.

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.
