Midnight at the end of a day is 2400 (AR 25-50 counts 0001 to 2400); the 24-hour clock writes the start of the day as 0000.
How to convert, in two lines
Standard to military: for a.m., write the hour with two digits and the minutes after it (7:05 a.m. is 0705); for p.m., add 12 to the hour (3:30 p.m. is 1530). The 12 o'clock hours are the exceptions: 12:15 p.m. is 1215 and 12:15 a.m. is 0015.
Military to standard: from 1300 on, subtract 12 and say p.m. (1745 is 5:45 p.m.); before 1200, drop the leading zero and say a.m. (0930 is 9:30 a.m.); 1200 to 1259 is the noon hour.
The Army's written rule
AR 25-50, Preparing and Managing Correspondence, para. 1-26, "Expressing time": "Military time will be expressed in a group of four digits, from 0001 to 2400, based on the 24–hour clock system. The first two digits represent the hour after midnight and the last two digits represent the minutes. For example, 1:37 p.m. civilian time is expressed as 1337 military time."
Two more lines from the same paragraph decide how it looks on paper: "The word "hours" will not be used in conjunction with military time," and "Civilian time is used when writing letters. Military time is used for memorandums." The memorandum generator writes times in a memorandum the same way.
