I just saw “Zero Dark Thirty” this afternoon and it was great! However, many people have approached me on-line telling me they have never heard this term before. It would be my honor to clear this up… It is a humorous term used by the military based on the 24-hour clock. The hours before 10 am start with a 0; so 1:00 am is 0100 and said as zero-one-hundred and so forth. Thus zero-dark hundred is any time after midnight while it is still dark: "They woke us up at zero-dark-hundred and ran us thru the obstacle course." Meaning they woke us up in the wee hours of the morning before daylight. Alternatively, many folks have also heard, “Oh Dark Thirty”. How it is pronounced greatly depends on which branch of the military you’ve served… In the Navy and Marine Corps, there was a lot of emphasis on pronouncing 0500 as "zero five hundred" instead of "oh five hundred," etc., and, as a result, we said "zero dark thirty" instead of "oh dark thirty." So the movie is very accurate in this regard.
This movie title means a very dark hour before dawn. This title was given to this movie because its scenes are mostly at night. The things that happened during the day were also planned during this dark hour. This is an indication that the movie revolves during the late hours of the night and before dawn.
zero dark thirty means "very late at night,some time between midnight and dawn. Either you have to stay up very late, or you have to get up too damned early.Pronounced as "oh dark" or "zero dark thirty".
