Going to bed for a 6:17 am alarm

Asleep by 9:02 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:32 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:02 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

Getting out the door for the school run or the commute into the city gets easier when 6:17 am is locked in properly. Choose a sound, hit start, and this browser alarm will ring at 6:17 am whether you're upstairs making lunches or still half asleep. Just keep the tab open so it has a chance to go off.

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.

This works well as a second alarm, one that isn't tangled up with phone notifications, do-not-disturb settings, or low battery. It genuinely won't ring if the tab gets closed or the device goes to sleep, so treat it as a backup or a work-desk tool rather than the only alarm for something important. On a 24-hour clock 6:17 am is written 06:17, and spoken aloud it's seventeen minutes past six in the morning. Written the Australian way that's 6.17 am, and typed in a hurry it's often 6:17am. Set an alarm for 6:17 am, set the alarm to 6:17 am, set my alarm for 6:17 am — all of it lands on this page and does the same thing.

Common questions

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.

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.
