Civilian time uses the numbers 1 to 12 to identify each of the 24 hours in a day. In military time, the hours are numbered from 00 to 24. Regular and military time both use minutes and seconds in exactly the same way. (For example 1:05PM would be 1305 hours.) When converting from regular to military time and vice versa, the minutes and seconds do not change. Midnight is written as 2400 or 0000.

When written, the colon is omitted and the time on the hours is often spoken as its decimal value. For instance, 6:00 a.m. would become 0600, and would be spoken as "zero six hundred", "oh six hundred", or "zero six zero zero". However none of these formatting or pronunciation details is in fact exclusively military, and all are common in the technical contexts in which the 24-hour clock is generally used in English-speaking countries.

When converting times after noon, simply add 12 to the number of hours.
