Online alarm clock for 2:28 am
Pause what you are doing and set the alarm for 2:28 am, so you can break away when it is time to meet the fishing vessel at Bluff wharf. That gives you a clear cue before 3:00 am, without repeatedly checking the clock while finishing the job already in front of you.
Keep this alarm page open while you work, and leave the browser running until the alert sounds. If you close either one, or let your phone or laptop go to sleep, the alarm may not wake you for the fishing vessel. Check that the volume is audible, then test a short alert if you are unfamiliar with your current sound settings.
Move quietly through the house before leaving for Bluff, as other people may still be asleep at 2:28 am. Put your keys, jacket and wharf gear together somewhere you can reach without switching on bright hallway lights. A moderate alarm volume placed close to you can provide the cue without carrying through every room; vibration can add a discreet backup if your phone supports it.
