Understanding Military Time: What is it and Why Convert it to Standard Time?

Military time is a timekeeping system used internationally by the military, emergency services, hospitals, and other organizations that require precise and unambiguous timekeeping. It is a 24-hour clock system, where each hour of the day is represented by a two-digit number ranging from 00 to 23.

While military time may be familiar to those who frequently use it, it can be a bit confusing for those who are used to the standard 12-hour clock system. This is why it is important to understand military time and know how to convert it to standard time.

Converting military time to standard time is important in many situations, especially when communicating with people who are not familiar with military time. It is also essential when working with time-sensitive data that requires standard time format.


In this section, we provide a brief introduction to military time and explain why it is essential to understand and convert it to standard time. This section can be followed by detailed steps on how to convert military time to standard time using JavaScript.

The Basics of Converting Military Time to Standard Time in Javascript

Converting military time to standard time is a common task when working with time in Javascript. Military time, also known as 24-hour time, represents time in a 24-hour clock format, whereas standard time represents time in a 12-hour clock format with AM/PM markers.

To convert military time to standard time in Javascript, you can use a combination of conditional statements and string manipulation. The following is a sample code snippet that demonstrates how to convert military time to standard time:

function convertMilitaryToStandardTime(militaryTime) {
var hour = parseInt(militaryTime.substring(0, 2));
var minute = militaryTime.substring(3, 5);
var period = hour >= 12 ? ‘PM’ : ‘AM’;
hour = hour % 12 || 12;
return hour + ‘:’ + minute + ‘ ‘ + period;

console.log(convertMilitaryToStandardTime(’22:30′)); // Output: 10:30 PM
console.log(convertMilitaryToStandardTime(’08:15’)); // Output: 8:15 AM

In the above code, we first extract the hour and minute from the military time string. We then determine the period (AM/PM) based on the hour value using a ternary operator. Finally, we convert the hour to standard time format and return the result as a formatted string.

By using the above code, you can easily convert military time to standard time in your Javascript applications.

Step-by-Step Guide to Writing a Military Time Conversion Function in Javascript

If you want to create a Javascript function that converts military time (24-hour clock time format) to standard time (12-hour clock time format), follow these steps:

  1. Declare a function and give it a name, for example “convertMilitaryToStandard”.
  2. Set the function parameter as militaryTime.
  3. Declare variables for hours, minutes, meridian (AM or PM), and convertedTime.
  4. Parse the hours and minutes from the militaryTime using substring method.
  5. Calculate the meridian based on the hours and set it to either “AM” or “PM”.
  6. Convert the hours to 12-hour format and assign it to the “convertedTime” variable.
  7. Add a “:” between the hours and minutes for the “convertedTime”.
  8. Return the final “convertedTime” with the meridian included.

Here is the final code for the function:

function convertMilitaryToStandard(militaryTime) {
  let hours = militaryTime.substring(0,2);
  let minutes = militaryTime.substring(2,4);
  let meridian = (hours >= 12) ? "PM" : "AM";
  let convertedTime = ((hours + 11) % 12 + 1) + ":" + minutes;
  return convertedTime + " " + meridian;

You can now use this function in your Javascript program to convert military time to standard time format.

Javascript Libraries for Easy Military Time Conversion: Pros and Cons
