Going to bed for a 7:55 am alarm

Asleep by 10:40 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:10 am — 5 full sleep cycles, about 7 hours
Asleep by 1:40 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

Getting out the door for the school run or the commute into the city gets easier when 7:55 am is locked in properly. Choose a sound, hit start, and this browser alarm will ring at 7:55 am whether you're upstairs making lunches or still half asleep. Just keep the tab open so it has a chance to go off.

Using it is simple: pick a ringtone from the list, press Start, and leave this tab open in your browser. The alarm runs entirely on this page, so closing the browser will stop it from going off. Come back a minute early if you're not sure you trust it yet.

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 7:55 am is written 07:55, and spoken aloud it's five to eight in the morning. You'll also see it written 7.55 am — a full stop instead of the colon means the same time. Whether you would say set alarm for 7:55 am or put an alarm on for 7:55 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.
