How Midnight becomes 0000
12:00 AM in military time is 0000. Midnight is the other exception: 12 AM becomes 0000, the start of the new day. A duty period that ends at midnight is written 2400 instead.
Both forms are in use and neither is wrong. A day starts at 0000 and ends at 2400, so a shift beginning at midnight begins at 0000 while a shift running until midnight ends at 2400. The clock itself never displays 2400 — it rolls from 2359 straight to 0000.
Writing it down
Four digits, no colon, no AM or PM: 0000. Spoken, that is “zero hundred hours”. If minutes are involved, they slot straight in without any change — 12:45 AM is 0045.
Common questions about 0000
What is Midnight in military time?
Midnight in military time is 0000. Midnight is one of the two exceptions to the usual rules: 12 AM becomes 0000, not 1200.
How do you say 0000 out loud?
0000 is spoken “zero hundred hours”. The word “hundred” is used because the minutes are zero; at 0030 you would say “zero thirty hours” instead.
Is 0000 AM or PM?
0000 is AM — it converts to 12:00 AM. Military time has no AM or PM at all: every hour from 0000 to 2300 has its own number, which is the whole point of the format.
