Going to bed for a 11:46 am alarm

Asleep by 2:31 am — 6 full sleep cycles, about 9 hours
Asleep by 4:01 am — 5 full sleep cycles, about 7 hours
Asleep by 5:31 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

Shift workers switching over around midday often need an alarm that isn't tied to their phone being nearby. This one rings at 11:46 am straight from the browser tab, so a laptop left open on the kitchen table can do the job just as well.

Select a sound, hit Start, and that's the whole setup. The countdown runs inside this browser tab rather than on your device's operating system, so it needs to remain open, on a phone or laptop, until the alarm actually goes off.

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 11:46 am is written 11:46, and spoken aloud it's fourteen minutes to twelve in the afternoon. Timetables and rosters may show it as 11:46, and handwritten notes as 11.46 am. Setting the alarm to 11:46 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.

Common questions

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

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.
