What 1600 means
1600 is 4:00 PM. Military time writes the hour and the minutes as four digits with no colon, so the 16 is the hour and the 00 is the minutes. Because the hour is 13 or higher, subtract 12 to get the time on a normal clock: 16 minus 12 is 4, so it is 4:00 PM.
Four in the afternoon. End of the standard duty day for many units, and the start of the first dog watch.
Saying 1600 out loud
You say “sixteen hundred hours”. The word “hundred” is there because the minutes are zero; if it were 1630 you would say “sixteen thirty hours” instead, and at 1605 it becomes “sixteen oh five hours” — minutes below ten get an “oh”.
