Going to bed for a 11:38 am alarm

Asleep by 2:23 am — 6 full sleep cycles, about 9 hours
Asleep by 3:53 am — 5 full sleep cycles, about 7 hours
Asleep by 5:23 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

Whether it's a reminder to leave for an appointment or the end of a lunch break that's gone on too long, 11:38 am works as a firm nudge in the middle of the day. Set it here and it'll ring at 11:38 am through your device's speakers until dismissed.

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.

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 11:38 am is written 11:38, and spoken aloud it's twenty-two minutes to twelve in the afternoon. Timetables and rosters may show it as 11:38, and handwritten notes as 11.38 am. 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

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.
