Going to bed for a 8:10 am alarm

Asleep by 10:55 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:25 am — 5 full sleep cycles, about 7 hours
Asleep by 1:55 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 8:10 am is locked in properly. Choose a sound, hit start, and this browser alarm will ring at 8:10 am whether you're upstairs making lunches or still half asleep. Just keep the tab open so it has a chance to go off.

Start by selecting a tone from the dropdown, then hit Start to lock it in. From that point the page does the counting, and it'll ring once the time is reached, but only if the tab is still open somewhere on your device. Closing it, or the browser entirely, cancels the alarm.

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 8:10 am is written 08:10, and spoken aloud it's ten past eight in the morning. You'll also see it written 8.10 am — a full stop instead of the colon means the same time. If you need it loud, turn the system volume up before you start: the alarm plays at whatever the device is set to.

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.
