Web alarm clock for 4:30 a.m.
You are only just waking at 4:30 am, before the work of opening the gates at the wholesale fish port has begun. Set this alarm to give yourself a clear starting signal while you shake off sleep, dress, and gather what you need. With 5:00 am approaching, you have a defined window to reach the entrance before the first busy movements around the port.
Your early gate duty needs a sound you can actually hear, so check the volume after setting the alarm and make sure silent mode will not suppress it. Keep the browser active and the phone awake until 4:30 am: if either stops running, the alarm may not sound, leaving the fish port gates unopened when crews expect access. A short test beforehand can confirm that the tone comes through at a useful level without relying on guesswork.
Once the fish port gates are open, avoid letting the early start consume every remaining hour before sunrise. If your duties allow you to return home after the handover, prepare a dark, quiet place in advance and keep later errands flexible. That makes the sleep left after 4:30 am easier to protect from bright screens, household noise, and an unnecessarily long detour.
