Convert 12 Hour Am Pm String To 24 Date Object Using Moment Js

Converting time from a 12-hour format with AM/PM to a 24-hour format might sound tricky, but with the help of Moment.js, it’s actually quite simple. If you've got a time string like "5:30 PM" and need to work with it in a more standard 24-hour format, follow along with this handy guide.

First things first, if you're not already using Moment.js in your project, you'll want to include it. You can easily add it to your HTML file like this:

Or if you're using npm, you can install it with:

npm install moment

Once you have Moment.js in your project, you can start converting your time strings. Let's say you have a time string in the format "5:30 PM" and you want to convert it to a 24-hour format. Here's how you can do it using Moment.js:

// Parse the time string into a Moment object
let timeString = '5:30 PM';
let timeObject = moment(timeString, 'h:mm A');

// Format the Moment object into a 24-hour time string
let formattedTime = timeObject.format('HH:mm');

console.log(formattedTime); // Output: 17:30

In the code snippet above, we first use Moment.js to parse the time string '5:30 PM' into a Moment object using the 'h:mm A' format, where 'h' represents the hour, 'mm' represents the minutes, and 'A' represents the AM/PM designation.

Next, we format the Moment object into a 24-hour time string using the 'HH:mm' format, where 'HH' represents the two-digit hour in 24-hour format, and 'mm' represents the two-digit minutes.

By running this code, you'll see that the time string '5:30 PM' has been successfully converted to '17:30' in 24-hour format.

Moment.js provides a powerful set of features for parsing, manipulating, and formatting dates and times in JavaScript. It makes handling time-related data a breeze, saving you time and effort in your projects.

Remember, Moment.js simplifies date and time operations in JavaScript, making tasks like converting between different time formats a straightforward process. Always make sure to include Moment.js in your projects to leverage its capabilities and streamline your coding experience.
