Going to bed for a 8:38 am alarm

Asleep by 11:23 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:53 am — 5 full sleep cycles, about 7 hours
Asleep by 2:23 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

Between the commute and the first coffee, 8:38 am is often the last checkpoint before the day properly starts. This tool sets a browser alarm for 8:38 am that rings through your device's speakers, handy for a desk you're already sitting at or a laptop open on the kitchen bench.

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.

Because this runs in the browser rather than on the phone's operating system, it sidesteps silent mode and do-not-disturb entirely, useful if your phone alarm has ever failed to go off for exactly that reason. Just be aware it needs the tab open and the screen or laptop lid to stay on to actually ring. On a 24-hour clock 8:38 am is written 08:38, and spoken aloud it's twenty-two minutes to nine in the morning. Written the Australian way that's 8.38 am, and typed in a hurry it's often 8:38am. Whether you would say set alarm for 8:38 am or put an alarm on for 8:38 am, the steps are the same: pick a sound, press Start, leave the tab open.

Common questions

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.

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.
