Going to bed for a 5:49 am alarm

  • Asleep by 8:34 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 10:04 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 11:34 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

Setting an alarm for 5:49 am while everyone else is asleep can feel like cheating the clock, but it's usually just planning ahead for an early departure or a shift that starts before sunrise. This will sound at 5:49 am through your speakers, whether it's the depths of winter or a short summer night.

Start by selecting a tone from the dropdown, then hit Start to lock it in. From that point the page does the counting, and it'll ring once the time is reached, but only if the tab is still open somewhere on your device. Closing it, or the browser entirely, cancels the alarm.

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 5:49 am is written 05:49, and spoken aloud it's eleven minutes to six in the morning. Timetables and rosters may show it as 05:49, and handwritten notes as 5.49 am. Setting the alarm to 5:49 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.
