Going to bed for a 11:13 am alarm

  • Asleep by 1:58 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:28 am — 5 full sleep cycles, about 7 hours
  • Asleep by 4:58 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.

How to use the online alarm clock

Between video calls and a late lunch, it's easy to lose track of the clock, which is why 11:13 am shows up so often as a midday alarm. This rings straight from your browser at 11:13 am. No app, no account, just a tab that needs to stay open.

After picking a tone, press Start and leave the page open. It doesn't need an internet connection once it's running, but it does need the tab itself to stay open, so avoid closing the browser or letting the device fall asleep before the time is reached.

It's free to use, doesn't need an account, and works the same in any modern browser, but it's honestly not meant to replace your phone for anything you can't afford to sleep through. Keep the tab open and the device awake, and it'll ring reliably at the time you set. On a 24-hour clock 11:13 am is written 11:13, and spoken aloud it's thirteen minutes past eleven in the morning. Written the Australian way that's 11.13 am, and typed in a hurry it's often 11:13am. Whether you would say set alarm for 11:13 am or put an alarm on for 11:13 am, the steps are the same: pick a sound, press Start, leave the tab open.

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.
