Going to bed for a 11:23 am alarm

  • Asleep by 2:08 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:38 am — 5 full sleep cycles, about 7 hours
  • Asleep by 5:08 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

Midday shifts, split rosters, and long lunch breaks all make 11:23 am a useful checkpoint. Choose a sound, set this for 11:23 am, and leave the tab open. It'll ring right through your laptop speakers whether you're at a desk or on the couch during a break.

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.

The advantage of a browser alarm is volume and reliability at a desk: laptop speakers are often louder and easier to hear across a room than a phone left in a bag. The catch is that it depends entirely on the tab staying open; if the browser closes or the laptop sleeps, the alarm won't fire. On a 24-hour clock 11:23 am is written 11:23, and spoken aloud it's twenty-three minutes past eleven in the morning. You'll also see it written 11.23 am — a full stop instead of the colon means the same time. Setting the alarm to 11:23 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.

Common questions

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
