angularjs How to get time difference from ZoneDateTime in javascript

Getting Time Difference from ZoneDateTime in Javascript using AngularJS

If you are working with AngularJS and need to calculate the time difference between two ZoneDateTime objects, you can use the built-in Date object in JavaScript. Here are some methods you can use:

Method 1: Use getTime() method

This method involves converting the ZoneDateTime objects to Unix timestamps using the getTime() method and then subtracting them to get the time difference in milliseconds:

      var date1 = new Date('2021-05-15T10:00:00.000Z');
      var date2 = new Date('2021-05-15T11:30:00.000Z');
      var diff = Math.abs(date2.getTime() - date1.getTime());
      console.log(diff); //Output: 5400000 (milliseconds)

Method 2: Use moment.js library

Moment.js is a powerful JavaScript library that simplifies working with dates and times. You can use it to calculate the time difference between two ZoneDateTime objects like this:

      var date1 = moment('2021-05-15T10:00:00.000Z');
      var date2 = moment('2021-05-15T11:30:00.000Z');
      var diff = date2.diff(date1, 'milliseconds');
      console.log(diff); //Output: 5400000 (milliseconds)

Using moment.js has the advantage of being more straightforward and providing more options for formatting and manipulating dates and times.


Calculating the time difference between two ZoneDateTime objects in JavaScript is relatively straightforward using either the built-in Date object or a library like moment.js. Depending on your needs and experience, you can choose the method that works best for you.
