Going to bed for a 7:37 am alarm

Asleep by 10:22 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:52 pm — 5 full sleep cycles, about 7 hours
Asleep by 1:22 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

Some people set this for 7:37 am because their phone alarm gets silenced by early notifications; others just want a second, louder reminder. Either way, pick 7:37 am, choose a sound, press start, and leave the tab open. It'll ring at 7:37 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 7:37 am is written 07:37, and spoken aloud it's twenty-three minutes to eight in the morning. Written the Australian way that's 7.37 am, and typed in a hurry it's often 7:37am. Set an alarm for 7:37 am, set the alarm to 7:37 am, set my alarm for 7:37 am — all of it lands on this page and does the same thing.

Common questions

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.

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
