Going to bed for a 3:08 am alarm

Asleep by 5:53 pm — 6 full sleep cycles, about 9 hours
Asleep by 7:23 pm — 5 full sleep cycles, about 7 hours
Asleep by 8:53 pm — 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

Newborns don't care what time it is, and neither does an early shift roster. If 3:08 am is when you need to be up and moving, this page will ring at exactly 3:08 am through your browser, giving parents and shift workers one less thing to double-check before they finally shut their eyes.

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 3:08 am is written 03:08, and spoken aloud it's eight minutes past three at night. Timetables and rosters may show it as 03:08, and handwritten notes as 3.08 am. 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

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.
