Going to bed for a 4:22 am alarm

  • Asleep by 7:07 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 8:37 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 10:07 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 4:22 am

As you hand responsibility for the dawn departure to the next person, agree that 4:22 am is the cue to get moving towards the Tongariro track. That leaves 38 minutes before 5:00 am for the changeover, final gear checks and getting everyone into the vehicle without turning the handover into a rushed exchange.

Once the alarm is set, its page may sit behind another browser tab while the route or weather details are checked. Return to it before settling down and confirm that the alarm still appears active. If this tab is closed or the phone or laptop goes to sleep, no sound will play, so the Tongariro track departure could lose the cue the incoming person is expecting.

During a pre-dawn handover, keep the screen just bright enough to read names, times and packed items clearly. Lowering its brightness and using a warmer display setting can make the contrast less harsh in a dark room. Put the phone face down after the check, then leave a small light near the gear so the person taking over can find boots and layers without staring at a bright screen at 4:22 am.
