Going to bed for a 10:59 am alarm

Asleep by 1:44 am — 6 full sleep cycles, about 9 hours
Asleep by 3:14 am — 5 full sleep cycles, about 7 hours
Asleep by 4:44 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

Some people set this for 10:59 am because their phone alarm gets silenced by early notifications; others just want a second, louder reminder. Either way, pick 10:59 am, choose a sound, press start, and leave the tab open. It'll ring at 10:59 am until you close it or hit stop.

Pick whichever sound you're most likely to actually notice, then press Start. The alarm is tied to this browser tab, so it needs to stay open. Minimising the window is fine, but closing the tab or the browser will stop the countdown before it ever rings.

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 10:59 am is written 10:59, and spoken aloud it's one minutes to eleven in the morning. You'll also see it written 10.59 am — a full stop instead of the colon means the same time. Setting the alarm to 10:59 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.
