Minutes never convert — only the hour does. Any minute works the same way: 0407 is 4:07 AM, 0452 is 4:52 AM. For any other time, the military time converter takes both directions.
Where 0400 shows up
Four in the morning: bakers, produce markets, and airport openers. 0400 call times exist so everything is ready by the time the 9-to-5 world shows up.
