To convert standard time to military time, add 12 hours to times after 12 p.m. and remove the punctuation. Military time runs on a 24-hour system without punctuation, while standard time uses a 12-hour system and a colon to separate hours and minutes.

Remove the colon from the time you have converted. For example, 13:00 becomes 1300.
Military time always includes 4 digits: two for the hours and two for the minutes. For single-digit hour times, like 400, add a digit at the beginning, so 4 becomes 04, and 400 becomes 0400.
