Going to bed for a 4:33 am alarm

  • Asleep by 7:18 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 8:48 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 10:18 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 4:33 am

Getting ready early for a pre-ebb nets check in the Bay of Islands gives you time to set a 4:33 am alarm before sorting the rest of your gear. The alert falls well ahead of 5:00 am, so that round hour can remain a useful reference point for leaving the shore or completing another preparation.

While you check tide notes or weather details, this alarm page may move into the background. It should continue counting, although a phone’s browser may restrict background activity, so keep the sound turned up and return here shortly before 4:33 am if timing matters. For the nets check, no alarm will sound after this page has been closed or the phone has gone to sleep; use a separate device alarm as a backup when you cannot keep the browser active.

Before stepping out for the nets, arrange the light you will need while it is still night. Put a charged torch beside your keys, angle any work light towards the gear rather than your eyes, and lower the screen brightness once the alarm is set. That avoids fumbling in darkness at 4:33 am and preserves a clear view when moving between the vehicle, ramp and boat.
