Going to bed for a 9:25 am alarm

Asleep by 12:10 am — 6 full sleep cycles, about 9 hours
Asleep by 1:40 am — 5 full sleep cycles, about 7 hours
Asleep by 3:10 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 9:25 am is locked in properly. Choose a sound, hit start, and this browser alarm will ring at 9:25 am whether you're upstairs making lunches or still half asleep. Just keep the tab open so it has a chance to go off.

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.

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 9:25 am is written 09:25, and spoken aloud it's twenty-five past nine in the morning. Written the Australian way that's 9.25 am, and typed in a hurry it's often 9:25am. Set an alarm for 9:25 am, set the alarm to 9:25 am, set my alarm for 9:25 am — all of it lands on this page and does the same thing.

Common questions

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

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.
