Moment.js - How to convert date string into date?


Solution 1

If you are getting a JS based date String then first use the new Date(String) constructor and then pass the Date object to the moment method. Like:

var dateString = 'Thu Jul 15 2016 19:31:44 GMT+0200 (CEST)';
var dateObj = new Date(dateString);
var momentObj = moment(dateObj);
var momentString = momentObj.format('YYYY-MM-DD'); // 2016-07-15

In case dateString is 15-07-2016, then you should use the moment(date:String, format:String) method

var dateString = '07-15-2016';
var momentObj = moment(dateString, 'MM-DD-YYYY');
var momentString = momentObj.format('YYYY-MM-DD'); // 2016-07-15

moment.locale();         // en
moment().format('LT');   // 4:59 PM
moment().format('LTS');  // 4:59:47 PM
moment().format('L');    // 12/08/2020
moment().format('l');    // 12/8/2020
moment().format('LL');   // December 8, 2020
moment().format('ll');   // Dec 8, 2020
moment().format('LLL');  // December 8, 2020 4:59 PM
moment().format('lll');  // Dec 8, 2020 4:59 PM
moment().format('LLLL'); // Tuesday, December 8, 2020 4:59 PM
moment().format('llll'); // Tue, Dec 8, 2020 4:59 PM

Solution 3

if you have a string of date, then you should try this.

const FORMAT = "YYYY ddd MMM DD HH:mm";

const theDate = moment("2019 Tue Apr 09 13:30", FORMAT);
// Tue Apr 09 2019 13:30:00 GMT+0300

const theDate1 = moment("2019 Tue Apr 09 13:30", FORMAT).format('LL')
// April 9, 2019

or try this :

const theDate1 = moment("2019 Tue Apr 09 13:30").format(FORMAT);

    Following up from my previous post: Javascript Safari: new Date() with strings returns invalid date when typed

    I am using Moment.js to convert a date string into a date field based on user input in the text box.

    This is to prevent the problem I described in the linked post for Safari and Firefox not able to render the date when Chrome is fine.

    Here is the code snipper:

    var tempDate = moment(userInputFieldDate).format('DD-MM-YYYY');

    In Chrome, it does work fine (it use to work with the Javascript Date object too) but gives me the moment.js deprecation warning

    Deprecation warning: moment construction falls back to js Date. This is discouraged and will be removed in upcoming major release. Please refer to for more info. Arguments: [object Object] Error

    On Firefox and Safari is just gives an UNDEFINED DATE in the alert window. So not entirely sure what should I be doing to convert the date string to a Date object.

    Any suggestions on this issue?
