Online alarm clock for 2:20 am
Handing the island sanctuary predator-trap check to the next person at 02:20 means making the handover precise: set the alarm for the agreed departure time, point out which trap line comes first, and confirm who is carrying the field notes. If the round begins at 03:00, the remaining time can cover a clear briefing and a final check of wet-weather gear.
While the incoming checker gets ready, keep this alarm page open and leave its sound enabled. Moving the page behind field maps or shift records should not change the time you set, but check that the alarm remains visible among the browser’s open pages so it is not closed during the handover. Because the browser alarm cannot sound after its session ends or the computer sleeps, the predator-trap check could be missed; use a separate alarm as backup if nobody will be watching the screen.
Preparing for a sanctuary round in the middle of the night calls for as little bright light as the task allows. Lower the screen brightness before reviewing trap locations, use a warmer display setting if available, and enlarge the map or notes instead of bringing the screen close to your eyes. Once the 02:20 alarm is set, turn the display away from the person finishing the previous shift while keeping the volume audible.
