Get Difference Between 2 Dates In Javascript Duplicate

Have you ever wondered how you can get the difference between two dates in Javascript? Well, you're in luck because in this article, we'll walk you through a simple way to achieve this using Javascript.

One of the first steps in finding the difference between two dates is to ensure that you have the date objects in the correct format. Javascript provides a Date object that allows you to work with dates and times easily. You can create new Date objects by using the 'new Date()' constructor and passing in the desired date as a parameter.

var date1 = new Date('2022-01-01');
var date2 = new Date('2022-02-01');

Once you have your two date objects, you can calculate the difference between them in milliseconds using the subtraction operator.

var differenceInMs = date2 - date1;

Now, you may want to convert this difference into more meaningful units such as days, hours, minutes, or seconds. To convert milliseconds to days, you can divide the difference by the number of milliseconds in a day.

var differenceInDays = differenceInMs / (1000 * 60 * 60 * 24);

If you want to get the absolute difference (ignore the negative sign if the dates are in reverse order), you can use the Math.abs() method.

differenceInDays = Math.abs(differenceInDays);

Alternatively, you can also use external libraries like Moment.js to make date and time calculations easier and more robust. Moment.js provides a range of utilities for manipulating, formatting, and working with dates in Javascript. To use Moment.js for this task, you need to include it in your project by adding the script tag to your HTML file.

With Moment.js, you can achieve the same result in a more concise and readable way.

var date1 = moment('2022-01-01');
var date2 = moment('2022-02-01');
var differenceInDays = date2.diff(date1, 'days');

By following these steps, you can easily get the difference between two dates in Javascript using native Date objects or with the help of libraries like Moment.js. Understanding how to work with dates is essential in many software engineering tasks, and mastering these skills will make you more efficient and effective in your coding journey.
