Going to bed for a 8:38 am alarm

  • Asleep by 11:23 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 12:53 am — 5 full sleep cycles, about 7 hours
  • Asleep by 2:23 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.

Online alarm clock for 8:38 am

You’re halfway through another job when the 8:38 am alarm needs to pull you away to check the traps before the heat builds. That interruption leaves enough room to inspect them properly and deal with anything that needs attention before 9:00 am, rather than noticing the time only after the morning has become hotter.

Because the traps take you away from the screen, set the alarm and confirm that its active indicator remains visible before returning to your current task. Moving this page into the background generally leaves the alarm armed, although the browser may limit background activity. If the page is closed, or the phone or computer goes to sleep, no sound will play and the traps could go unchecked at the intended time. A separate phone alarm is a sensible backup if you will be outside.

While finishing the job already under way, look at where the early sunlight will fall when you head out. Position a hat and sunglasses beside the gear now, and angle the screen away from glare so the 8:38 am alert is easy to recognise. Having a torch handy can still help with shaded corners, even after the surrounding light has strengthened.

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.
