oh-dark-thirty
Ungodly early hour
Oh-dark-thirty is military slang for an unspecified early morning hour, typically before dawn when the sky is still dark.
The "oh" mimics 24-hour time format where early hours begin with zero: We shipped out at oh-dark-thirty.
Extended to civilian use, it suggests any inconveniently early time: My flight leaves at oh-dark-thirty.
