Going to bed for a 7:48 am alarm

Asleep by 10:33 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:03 am — 5 full sleep cycles, about 7 hours
Asleep by 1:33 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, 7:48 am is often the last checkpoint before the day properly starts. This tool sets a browser alarm for 7:48 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.

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 7:48 am is written 07:48, and spoken aloud it's twelve minutes to eight in the morning. Written the Australian way that's 7.48 am, and typed in a hurry it's often 7:48am. 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

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.

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.
