Going to bed for a 4:36 am alarm

  • Asleep by 7:21 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 8:51 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 10:21 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 4:36 am

You are just waking at 4:36 am, with the Tongariro trailhead still ahead and the dawn start shaping everything that follows. The alarm marks the moment to sit up, get dressed, check your packed gear, and move towards the car. Leaving these first tasks until 5:00 am could turn a calm departure into a hurried one.

Your Tongariro track departure depends on this page remaining open and the computer or phone staying awake; closing the page or letting the screen sleep means the alarm may never sound. Keeping it visible while you prepare makes the signal easier to rely on. The displayed time also provides a quick check that 4:36 am was selected correctly before attention shifts to boots, water, keys, and the drive.

Stepping outside for a pre-dawn Tongariro departure can feel noticeably damper and cooler than the indoor air suggests. At this hour, moisture may sit on the car windows, so allow a little time to clear the glass before driving. A light outer layer kept beside the door is practical while loading gear, and placing anything that must stay dry inside a closed pack helps protect it from dew or mist.
