Going to bed for a 6:05 am alarm

Asleep by 8:50 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:20 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:50 pm — 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

Some people set this for 6:05 am because their phone alarm gets silenced by early notifications; others just want a second, louder reminder. Either way, pick 6:05 am, choose a sound, press start, and leave the tab open. It'll ring at 6:05 am until you close it or hit stop.

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.

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 6:05 am is written 06:05, and spoken aloud it's five past six in the morning. Timetables and rosters may show it as 06:05, and handwritten notes as 6.05 am. Setting the alarm to 6:05 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.

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.
