How to say 0000
Say “zero hundred”. That is common usage: no manual we found spells out 0000 to 0059 in words, and on the radio they are read digit by digit (the FAA gives 0000 as “zero zero zero zero”). Spoken, “hours” often follows: “zero hundred hours”. In writing, the Army and Air Force leave “hours” out. How military time is said and written.
