Going to bed for a 4:49 am alarm

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

Online alarm clock for 4:49 am

As you hand the post-storm inspection over to the next person, set the alarm for 4:49 am so they know when to check the yard, garage or low-lying entry for water. The alert leaves enough time to explain which spots usually collect runoff before 5:00 am, without sending them outside before they understand the job.

For this storm check, the alarm needs to be audible rather than merely visible on the screen. Confirm that your phone or computer is not in silent mode, keep the volume high enough to hear from the next room, and test the sound before relying on it. Because the alarm runs in the browser, it will not sound once the page is closed or the computer or phone has gone to sleep; the storm inspection could then be missed. Leave the page open and keep the equipment awake until 4:49 am.

After overnight rain, the person taking over should expect damp, heavy air outside at this hour, even if the storm itself has moved on. Before stepping out at 4:49 am, they can take a torch, wear shoes suited to wet ground and pause at the doorway to check whether the air still carries rain or another shower is approaching. Humidity can also leave paths, steps and handrails slick, so moving carefully matters more than finishing the inspection before 5:00 am.

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.
