Military Time

The military use the 24 hour clock, written with four digits, two for the hours and two for the minutes. Seconds are not normally used. Starting at midnight which is always written as "0000" and expressed as "zero hundred hours", but never as either "oh-hundred hours" or "2400" ("twenty four hundred hours"), the expression "oh" is a letter not a number.

It goes through until "2359", or one minute to midnight, said as "twenty three, fifty nine hours". Note that a colon is never inserted between the hours and the minutes digits, as sometimes seen elsewhere. A quarter to two in the afternoon is therefore "1345", or "thirteen forty five hours". See below for a conversion table for the hours of the day.
