Going to bed for a 8:04 am alarm

Asleep by 10:49 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:19 am — 5 full sleep cycles, about 7 hours
Asleep by 1:49 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

Some people set this for 8:04 am because their phone alarm gets silenced by early notifications; others just want a second, louder reminder. Either way, pick 8:04 am, choose a sound, press start, and leave the tab open. It'll ring at 8:04 am until you close it or hit stop.

Using it is simple: pick a ringtone from the list, press Start, and leave this tab open in your browser. The alarm runs entirely on this page, so closing the browser will stop it from going off. Come back a minute early if you're not sure you trust it yet.

Compared to a phone, this alarm has one job and nothing else competing for attention — no messages, no app switching. It's free and doesn't ask for sign-up, but it only works while the tab is open and the device stays awake, so it suits daytime use at a desk better than an overnight bedroom alarm. On a 24-hour clock 8:04 am is written 08:04, and spoken aloud it's four minutes past eight in the morning. Written the Australian way that's 8.04 am, and typed in a hurry it's often 8:04am. 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

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.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.

Will the alarm still ring if I close the browser tab?

No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.

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.
