In Navy parlance, a field day is a day, or specific period of time, devoted to heavy cleaning. When I was in the Navy, we typically devoted one evening each week to the field day. All ship's cooks, including the off duty watch, scrubbed every nook and cranny in the galley, bakery and food storage spaces.
