Web alarm clock for 3:00 a.m.
You are just waking up to open the gates at the wholesale fish landing, before the first deliveries roll in and the work begins. An alarm set for 3:00 am gives you a clear cue to sit up, get dressed, and gather the keys while the house is still quiet. Keep the phone within reach so you do not lose precious minutes searching for it in the dark.
Your early start depends on hearing the alert, so check the phone’s silent settings before you sleep. Raise the alarm volume separately from media volume, and choose a sound that remains audible without being startling. This browser alarm cannot wake you for the fish landing if the page is closed or the phone goes to sleep, so leave the page active and keep the phone awake until 3:00 am. A plugged-in phone also avoids an empty battery before the alarm sounds.
Outside noise can be unusually low at this hour, then rise quickly as tricycles, trucks, and workers approach the landing. Place the phone near your pillow while the surroundings are quiet, but use vibration as a second signal if an electric fan or passing vehicles may cover the sound. Once awake, listen for activity near the gate before stepping out, and carry a small torch for the dim approach.
