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

Question

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')

Well, your expected result is a bit different than your input, isn't it? 5:00:00pm => 15;04:16.913Z? I can see the two hours being a time zone difference, but 4:16.913? Never heard of a nanosecond-level offset for a time zone... — Heretic Monkey, Mar 13 '20 at 15:56

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);
