var date1 = moment(date, 'YYYY-MM-DD HH:mm T'); //undefined
Please help me out. I havee to this in both VueJs and Javascript

You should convert your timestamps to an ISO 8601 format including the UTC-offset. This can be done for instance using new Date().toISOString(). Then you can feed the timestamp into moment or, if you want to display the time for a different timezone, have a look at moment-timezone

I figure out the answer in this way:
var buildDate = "2020-07-13_7:07";
let releaseDate = buildDate .split('_');
let date = moment(date);
let newDate = moment(new Date(date.get('year'), date.get('month'), date.get('date'), date.get('hour'), date.get('minute'))).add(new Date().getTimezoneOffset()*-1, 'm').toDate();
let result = moment(newDate).format('MMM DD YYYY h:mm A');

how to do the date conversion in moment.js using javascript?

Here is my date string and i want to convert this into javascript date object.
Input: -- Wednesday, March 4th, 2020, 5:00:00 pm
Expected result: -- 2020-03-13T15:04:16.913Z'
I tried :
moment('Wednesday, March 4th, 2020, 5:00:00 pm').format('YYYY-MM-DDTHH:mm:ss\\Z')

You need to inform Moment about the format of the string you're giving it.
From the documentation / display :
Wednesday = dddd
March = MMMM
4th = Qo
2020 = YYYY
5:00:00 pm = h:mm:ss a
So yout input format is "dddd, MMMM Qo, YYYY, h:mm:ss a"
Now you can create a valid Moment and manipulate it.
moment('Wednesday, March 4th, 2020, 5:00:00 pm', "dddd, MMMM Qo, YYYY, h:mm:ss a").format(whatever)

Firstly you need to inform moment the format of the expected input , followed by format() to convert the same into required format.
Based on their docs: https://momentjs.com/docs/#/displaying/
Check this code out. It will help you get started:
var input = "Wednesday, March 4th, 2020, 5:00:00 pm";
var date = moment(input, "dddd, MMMM Do, YYYY, h:mm:SSSS a").format(
"YYYY-MM-DDTHH:mm:ss\\Z"
);
console.log(date);

Moment.js conversion of RFC2822 date

I have a date as '04 FEB 1994' which I'm trying to convert into a date object for comparison.
I've tried a whole bunch of variations, the current one is...
var trydate = moment(licDob, "DD-MMM-YYYY");
var momentObj = moment(trydate);
var momentString = momentObj.format('YYYY-MM-DD');
where licDob is 04 FEB 1994. momentObj is coming back as 853506000000 which makes momentString 1997-01-18.
Guidance much appreciated.

use
var newTry = moment(licDob,'DD MMM YYYY').toDate()
considering you want to convert it to Date()

You were close the the right solution. You have to use the moment constructor with 2 parameters. The 1st parameter is your string date and the 2nd is the format.
In your case the correct format is DD MMM YYYY
const stringDate = "04 FEB 1994";
const momentDate = moment(stringDate, "DD MMM YYYY");
console.log("Formatted:", momentDate.format("DD/MM/YYYY"));
console.log("EPOCH:", momentDate.valueOf())

Format the current date and time using momentjs

I want to convert the current date and time to in the following way using moment.js.
Current date and time using javascript new Date(): Thu Jul 12 2018 09:28:51 GMT+0530 (India Standard Time) and want to convert the above format to below mentioned format.
1. Thu, 12 Jul 2018 09:31:37 GMT
2. 2018-07-12T09:31:38Z

You can learn more about formatting with moment.js here.
Escape words in formatting with escaping-characters "[]".
console.log(moment());
console.log(moment().format('ddd, DD MMM YYYY HH:mm:ss [GMT]'));
console.log(moment().format('YYYY-MM-DD[T]HH:mm:ss[Z]'));
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.2/moment.min.js"></script>

you can also try like below for
nodejs
var moment = require('moment');
var format1 = moment().utcOffset(330).format('ddd, DD MMM YYYY HH:mm:ss [GMT]')
var format2 = moment().toDate();
console.log(format1);
console.log(format2);
angular
import moment from 'moment';
var format1 = moment().utcOffset(330).format('ddd, DD MMM YYYY HH:mm:ss [GMT]')
var format2 = moment().toDate();
console.log(format1);
console.log(format2);
Install moment like below
npm install --save moment
Html javascript
var format1 = moment().utcOffset(330).format('ddd, DD MMM YYYY HH:mm:ss [GMT]')
var format2 = moment().toDate();
console.log(format1);
console.log(format2);
moment source script
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.2/moment.min.js"></script>

You can use toGMTSting method to convert local time into GMT format. Hope this helps..
console.log(new Date().toGMTString());
console.log(new Date("Fri Jan 20 2012 11:51:36 GMT-0530").toGMTString());

You can try these also:
var moment = require('moment');
let startDate= new moment('11/22/1990','MM/DD/YYYY').format("YYYY/MM/DD");
You can also understand these:
let otherDate= 1399919400000;
var neweDate = moment(otherDate).format('DD/MM/YYYY');
//My neweDate output is "13/05/2014";
moment.locale('cs');
console.log(moment.locale()); // en
moment("2010-10-20 4:30", "YYYY-MM-DD HH:mm"); // parsed as 4:30 local time
moment("2010-10-20 4:30 +0000", "YYYY-MM-DD HH:mm Z"); // parsed as 4:30 UTC
You can verify the date also:
moment("not a real date").isValid(); // false
moment("2010 13", "YYYY MM").isValid(); // false (not a real month)
moment("2010 11 31", "YYYY MM DD").isValid(); // false (not a real day)
moment("2010 2 29", "YYYY MM DD").isValid(); // false (not a leap year)
moment("2010 notamonth 29", "YYYY MMM DD").isValid(); // false (not a real month name)
You can create a Moment with a pre-existing native Javascript Date object.
var day = new Date(2011, 9, 16);
var dayWrapper = moment(day);
You can create a moment with an array of numbers that mirror the parameters passed to new Date()
[year, month, day, hour, minute, second, millisecond]
moment([2010, 1, 14, 15, 25, 50, 125]); // February 14th, 3:25:50.125 PM
Any value past the year is optional, and will default to the lowest possible number.
moment([2010]); // January 1st
moment([2010, 6]); // July 1st
moment([2010, 6, 10]); // July 10th

Dynamically convert timestamp to a different timezone [duplicate]

This question already has answers here:
How to convert Moment.js date to users local timezone?
(5 answers)
Closed 6 years ago.
I am using moment.js and moment-timezone. how can I create a function to convert 2016-06-12 06:22:18 UTC time to the user's timezone time and then format the time to Jun 12, 2015 6:22 PM
for example:
updateTime("2016-06-12 06:22:18");
if in chicago, the output will be:
"Jun 12, 2016, 1:22 AM"

You can try something like this.
moment.utc("2016-06-12 06:22:18", "YYYY-MM-DD HH:mm:ss").tz('America/Chicago').format("MMM D, YYYY, hh:mm a")

Hey this links may help you
https://gist.github.com/founddrama/2182389
https://www.sitepoint.com/managing-dates-times-using-moment-js/
http://momentjs.com/timezone/docs/
Examples:
moment().format('MMMM Do YYYY, h:mm:ss a'); // June 20th 2016, 11:10:20 am
moment().format('dddd'); // Monday
moment().format("MMM Do YY"); // Jun 20th 16
moment().format('YYYY [escaped] YYYY'); // 2016 escaped 2016
moment().format();
moment.tz('2016-01-01', 'America/Chicago').format('z');

You might want to look at this answer, perhaps: Get current timestamp from specific timezone
They solved by taking the time in UTC and converting it in the specific time
var utcEpochSeconds = dateObj.getTime() + (dateObj.getTimezoneOffset() * 60000);

The function you need would be like this :
function getLocalDate (input)
{
var dt= moment.utc(input);
dt.add(moment().utcOffset(),'minutes');
return moment(dt).format('MMM D, YYYY, hh:mm a');
};
Or this :
function getLocalDate(input)
{
return moment.utc(input).local().format('MMM D, YYYY, hh:mm a');
};
