Going to bed for a 10:01 am alarm

Asleep by 12:46 am — 6 full sleep cycles, about 9 hours
Asleep by 2:16 am — 5 full sleep cycles, about 7 hours
Asleep by 3:46 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 10:01 am is locked in properly. Choose a sound, hit start, and this browser alarm will ring at 10:01 am whether you're upstairs making lunches or still half asleep. Just keep the tab open so it has a chance to go off.

Set your preferred sound, press Start, then leave the tab where it is. Everything happens inside the browser — no background app, no notification pushed from a server — so an open tab is what actually makes the alarm ring at the right time.

Unlike a phone alarm, this one won't ring if you close the tab, put the computer to sleep, or shut the lid, so it suits a desk, a kitchen bench, or anywhere the device stays powered on and awake. It's free to use and doesn't need an account, but it's not built for unattended overnight use. On a 24-hour clock 10:01 am is written 10:01, and spoken aloud it's one minutes past ten in the morning. Timetables and rosters may show it as 10:01, and handwritten notes as 10.01 am. Set an alarm for 10:01 am, set the alarm to 10:01 am, set my alarm for 10:01 am — all of it lands on this page and does the same thing.

Common questions

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

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.
