Going to bed for a 6:51 am alarm

Asleep by 9:36 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:06 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:36 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 6:51 am because their phone alarm gets silenced by early notifications; others just want a second, louder reminder. Either way, pick 6:51 am, choose a sound, press start, and leave the tab open. It'll ring at 6:51 am until you close it or hit stop.

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 6:51 am is written 06:51, and spoken aloud it's nine minutes to seven in the morning. You'll also see it written 6.51 am — a full stop instead of the colon means the same time. Whether you would say set alarm for 6:51 am or put an alarm on for 6:51 am, the steps are the same: pick a sound, press Start, leave the tab open.

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.
