Going to bed for a 10:50 am alarm

  • Asleep by 1:35 am — 6 full sleep cycles, about 9 hours
  • Asleep by 3:05 am — 5 full sleep cycles, about 7 hours
  • Asleep by 4:35 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 the commute and the first coffee, 10:50 am is often the last checkpoint before the day properly starts. This tool sets a browser alarm for 10:50 am that rings through your device's speakers, handy for a desk you're already sitting at or a laptop open on the kitchen bench.

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.

This works well as a second alarm, one that isn't tangled up with phone notifications, do-not-disturb settings, or low battery. It genuinely won't ring if the tab gets closed or the device goes to sleep, so treat it as a backup or a work-desk tool rather than the only alarm for something important. On a 24-hour clock 10:50 am is written 10:50, and spoken aloud it's ten to eleven in the morning. Timetables and rosters may show it as 10:50, and handwritten notes as 10.50 am. Setting the alarm to 10:50 am tomorrow morning works the same way: if the time has gone for today, the count runs through to it.

Common questions

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.

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.
