Going to bed for a 8:36 am alarm

Asleep by 11:21 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:51 am — 5 full sleep cycles, about 7 hours
Asleep by 2:21 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 mornings mean footy training drop-offs, an early meeting, or getting the kids to school on time, 8:36 am is worth locking in properly. This rings straight from your browser at 8:36 am, and keeps ringing until you tell it to stop. No phone required nearby.

Pick whichever sound you're most likely to actually notice, then press Start. The alarm is tied to this browser tab, so it needs to stay open. Minimising the window is fine, but closing the tab or the browser will stop the countdown before it ever rings.

It's free to use, doesn't need an account, and works the same in any modern browser, but it's honestly not meant to replace your phone for anything you can't afford to sleep through. Keep the tab open and the device awake, and it'll ring reliably at the time you set. On a 24-hour clock 8:36 am is written 08:36, and spoken aloud it's twenty-four minutes to nine in the morning. You'll also see it written 8.36 am — a full stop instead of the colon means the same time. Set an alarm for 8:36 am, set the alarm to 8:36 am, set my alarm for 8:36 am — all of it lands on this page and does the same thing.

Common questions

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.

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.
