Going to bed for a 8:19 am alarm

Asleep by 11:04 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:34 am — 5 full sleep cycles, about 7 hours
Asleep by 2:04 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

If the school run is tight, an alarm at 8:19 am buys you the minutes you actually need to get everyone dressed, fed, and out the door. Set the time, choose a tone that won't get ignored, and this page will ring at 8:19 am through your speakers for as long as you let it.

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.

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 8:19 am is written 08:19, and spoken aloud it's nineteen minutes past eight in the morning. Written the Australian way that's 8.19 am, and typed in a hurry it's often 8:19am. Whether you would say set alarm for 8:19 am or put an alarm on for 8:19 am, the steps are the same: pick a sound, press Start, leave the tab open.

Common questions

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.

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.
