Going to bed for a 11:15 am alarm

Asleep by 2:00 am — 6 full sleep cycles, about 9 hours
Asleep by 3:30 am — 5 full sleep cycles, about 7 hours
Asleep by 5:00 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

Setting an alarm for 11:15 am in the middle of the day sounds unnecessary until you've missed a lunch meeting because you were heads-down in something else. This rings through your browser at 11:15 am, loud enough to notice at a desk, without needing your phone within reach.

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 11:15 am is written 11:15, and spoken aloud it's quarter past eleven in the morning. Written the Australian way that's 11.15 am, and typed in a hurry it's often 11:15am. 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

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.
