0900 Military Time

What 0900 means

0900 is 9:00 AM. Military time writes the hour and the minutes as four digits with no colon, so the 09 is the hour and the 00 is the minutes. The hour is below 12, so it is a morning time and the hour does not change — the leading zero is just padding to keep every time four digits long.

Nine in the morning. The last hour written with a leading zero; from 1000 onward all four digits are significant.

Saying 0900 out loud

You say “zero nine hundred hours”. The word “hundred” is there because the minutes are zero; if it were 0930 you would say “zero nine thirty hours” instead, and at 0905 it becomes “zero nine oh five hours” — minutes below ten get an “oh”.
