Going to bed for a 3:48 am alarm

  • Asleep by 6:33 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 8:03 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 9:33 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 3:48 am

While you wait for the scheduled generator check at a DOC hut, set the alarm for 3:48 am and keep an eye on the remaining night. That gives you a clear cue to collect a torch, jacket, and keys before heading outside. You will still have 12 minutes to inspect the generator and note anything unusual before 4:00 am.

Because this alarm supports a specific hut task, leave the browser running after confirming that 3:48 am is displayed and the sound is audible. If you close the browser or allow the phone to sleep, the alarm may not sound, and the generator check could be missed. Keep the phone powered, use a charger if one is available, and set a separate offline alarm when the timing cannot slip.

A generator inspection before dawn can disturb everyone sleeping in the hut, even when the machinery is outside. Prepare your boots and gear quietly, keep the screen dim, and disable unnecessary notification sounds before 3:48 am. When the alarm goes off, silence it promptly and use a low torch setting indoors. Closing doors gently and avoiding conversation until you are outside helps protect the sleep of other trampers sharing the house.
