First,before we dive into how to convert military time to standard or vice versa. Let us specify that there are two major systems of showing time: the 12-hour and the 24-hour.

In North America, almost all civilians prefer the 12-hour clock. It is sectioned into two parts: ante meridiem- A.M and Post Meridiem -P.M. each have 12 hours from midnight to noon and from noon to midnight respectively.

24-hour vs 12 hour clock system

Looking at the 24-hour clock system, the hours of the day count from 0-23, midnight to midnight. Midnight is normally displayed as 00:00. The last minute of every day is 23:59.

However, sometimes midnight is also shown as 24:00 to indicate the conclusion of the day. So for instance, you will say that Wednesday ends at 24:00 tonight while Thursday starts at 00:00.

Advantage And Disadvantage

As you compare the two systems, there are some disadvantages to the 12-hour clock system. The main disadvantage is a confusion that comes along telling whether any given time is in the A.M. or P.M or if 12:00 is noon or midnight.

It is very clear to calculate the duration of an event with the 24-hour clock. For instance, you can quickly tell if an event will take five hours when it runs from 11:30 to 16:30, instead of being told it started at 11:30 a.m. to 4:30 p.m.

Is the 24-hour clock more popular ?

for the same reasons, the 24-hour clock is more popular throughout the world, and was first used by the US Navy in 1920, and eventually by the army in 1942, during World War II.

In conclusion, the 24-hour clock is the international and the global standard for telling time. Even so, in areas of aviation, navigation, medical and emergency services, this time clock format is important to avoid ambiguities that can be dangerous. However, it is rare for it to be used in North America outside the armed forces.

The use of Military time is somewhat different from that of the 24-hour clock as discussed below

How to convert Military Time to Civilian (Standard) Time

  • For the hours below 10, add a zero in front of it. For example, 8:00 A.M. becomes 0800. The hours from 1 A.M to noon are just the same as civilian timekeeping
  • For the military time that is 1300 or greater, easily subtract 1200 to obtain the standard time. Like when someone wants to meet at 1445, subtract 1200 from that time (1445) to get 2:45 P.M. as simple as that!
  • For the conversion of the standard to military time, simply add 1200 to any time that falls above 1:00 P.M to 11:00 P.M. for example, 7:30 will be 1930.
  • Like an ace card, midnight is sometimes referred to like 2400 or 0000

Writing and speaking military time

Writing army time.

Unlike 12-hour and 24- hour clocks, with the use of military time, you do not place a colon between the hour and the minutes.

Speaking military time.

When saying the numbers, instead of ‘thousand’, always use ‘hundred’. Therefore, 0700 will be ‘Zero seven hundred’ or ‘Zero seven hundred hours’. 1000 will be ‘ten hundred’ and not ‘one thousand’. To mention time with minutes, pronounce every number. For instance:

  • 0002 (12:02) is ‘zero two’
  • 1530 (3:30 PM) is Fifteen Thirty Hours

Should I say Zero or (oh ,O)

Saying ‘zero’ is actually necessary as part of a military communication protocol. Sometimes, in the movies and TV, people mostly say ‘Oh’ instead of ’zero’. 0700 will be ’oh seven hundred’.

Should I say “hours” after the giving army time?

Also, depending on the branch of the military you are dealing with, some will say ‘hours’ after the specific time. For example, Soldiers and Airmen will say ‘fourteen hundred hours’ when referring to 2:00 P.M , on the other hand, Coast Guardsmen and Marines are more likely to say ‘fourteen hundred’.

At least, Throughout the several branches, it is common not to mention the ‘hours’ bit when engaging in a face-to-face conversation or when your meaning is quite obvious.

It can only be included when the written communication and the conversation are more formal or when you want to convey the message clearly without any confusion.
