Going to bed for a 11:09 am alarm

Asleep by 1:54 am — 6 full sleep cycles, about 9 hours
Asleep by 3:24 am — 5 full sleep cycles, about 7 hours
Asleep by 4:54 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 video calls and a late lunch, it's easy to lose track of the clock, which is why 11:09 am shows up so often as a midday alarm. This rings straight from your browser at 11:09 am. No app, no account, just a tab that needs to stay open.

There's a short list of sounds to choose from before you press Start — pick one that suits how deep a sleeper you are. Once it's set, the page keeps time in the background of your browser, and it'll sound at the moment you selected, provided the tab hasn't been closed.

Unlike a phone alarm, this one won't ring if you close the tab, put the computer to sleep, or shut the lid, so it suits a desk, a kitchen bench, or anywhere the device stays powered on and awake. It's free to use and doesn't need an account, but it's not built for unattended overnight use. On a 24-hour clock 11:09 am is written 11:09, and spoken aloud it's nine minutes past eleven in the morning. You'll also see it written 11.09 am — a full stop instead of the colon means the same time. Whether you would say set alarm for 11:09 am or put an alarm on for 11:09 am, the steps are the same: pick a sound, press Start, leave the tab open.

Common questions

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.

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.
