Extra word between date and time with date-fns - javascript

I am looking for a way to add an extra word between the date and time in date-fns library, but couldn't find such format. Right now I am using format function with MMM d hh:mm aa format.
The outcome is:
Nov 15 10:00 PM
Is there a way to get:
Nov 15 at 10:00 PM


I'd highly recommend reading and understanding the docs, before posting a question as simple as this.
As per documentation for the latest version (as of writing 2.29.3) the following will yield the required result.
format(new Date("Sep 2 2020 13:00"), "MMM dd 'at' HH:MM a")

How to display a date with date-fns formatted in a Mui DatePicker as Thursday, January 13th

In this example on CodeSandbox I'm trying to get the date formatted as dddd, MMMM Do and the expected result should be like Thursday, January 13th but instead is 0013, January 13th
As per date-fns documentation here Date-fns format, writing dddd should give me back the name of the day but I got instead 0013 and I don't understand why.
I need help on what is wrong with the way I'm writing the date format and get the name of the day instead of that 0013.

You are using a new version of date-fns https://date-fns.org/v2.16.1/docs/format.
You may use format="iiii, MMMM Do".

How to customize year format in a date format using moment.js?

I need to get the following format using moment.js
Thu, 10 Oct 16, 2:00PM
The closest format I found using moment.js is using the following function.
moment(dateVar).format('llll')
where dataVar is the required date object.The output looks as follows
Thu, Oct 16, 2016 12:00 AM
I could not find any way to customise this date format or get the required result.

According to the moment docs you should be able to get your result by passing the following formatting string:
moment(dateVar).format('ddd, DD MMM YY, H:mmA');
I think this string should get you the desired result.
If I run it with the current date it returns this:
moment(new Date()).format('ddd, DD MMM YY, H:mmA');
//"Wed, 02 Nov 16, 10:25AM"
And extensive list of your display options with formatting strings is here:
http://momentjs.com/docs/#/displaying/

See http://momentjs.com/docs/#/displaying/
What you need is
ddd, D MMM YY, h:mmA
ddd - Day of week
D -Day of month
etc

Formatting time using moment JS shows incorrect Date

I have time coming from server in certain format for example time is (1473286826319). Using MomentJS library
moment(1473286826319).format()
// output 2016-09-07T16:20:26-06:00 i.e sep 7 2016
However when I use custom formating style as below
moment(1473286826319).format('dddd, MMMM d, YYYY, h:mm A');
// output Wednesday, September 3, 2016, 4:20 PM
I have the date going back from Sept 7 to Sept 3 and rest of the data is accurate. Is there something I am doing wrong?

You are using a small d which is the Day of Week. If you want the Day of Month use a D or a DD for leading zeros.

Format date with Moment.js

I have a string in this format:
var testDate = "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"
I would like to use Moment.js get it in this format mm/dd/yyyy : 04/12/2013 for display.
I tried to do it using this method,
moment(testDate,'mm/dd/yyyy');
Which errors and says there is no such method called replace? Am I approaching this in the wrong way?
Edit
I should also mention that I am using a pre-packaged version of Moment.js, packaged for Meteor.js
Object [object Date] has no method 'replace' : The Exact error from the console

The 2nd argument to moment() is a parsing format rather than an display format.
For that, you want the .format() method:
moment(testDate).format('MM/DD/YYYY');
Also note that case does matter. For Month, Day of Month, and Year, the format should be uppercase.

Include moment.js and using the below code you can format your date
var formatDate= 1399919400000;
var responseDate = moment(formatDate).format('DD/MM/YYYY');
My output is "13/05/2014"

moment().format(); // "2019-08-12T17:52:17-05:00" (ISO 8601, no fractional seconds)
moment().format("dddd, MMMM Do YYYY, h:mm:ss a"); // "Monday, August 12th 2019, 5:52:00 pm"
moment().format("ddd, hA"); // "Mon, 5PM"

You Probably Don't Need Moment.js Anymore
Moment is great time manipulation library but it's considered as a legacy project, and the team is recommending to use other libraries.
date-fns is one of the best lightweight libraries, it's modular, so you can pick the functions you need and reduce bundle size (issue & statement).
Another common argument against using Moment in modern applications is its size. Moment doesn't work well with modern "tree shaking" algorithms, so it tends to increase the size of web application bundles.
import { format } from 'date-fns' // 21K (gzipped: 5.8K)
import moment from 'moment' // 292.3K (gzipped: 71.6K)
Format date with date-fns:
// moment.js
moment().format('MM/DD/YYYY');
// => "12/18/2020"
// date-fns
import { format } from 'date-fns'
format(new Date(), 'MM/dd/yyyy');
// => "12/18/2020"
More on cheat sheet with the list of functions which you can use to replace moment.js: You-Dont-Need-Momentjs

var moment = require('moment');
let yourdate = '2021-01-02T07:57:45.121Z'; // for example
moment(yourdate).format('MM/DD/YYYY');
// output : 01-02-2021
moment(yourdate).format('DD-MMM-YYYY');
// output : 01-Jan-2021

For fromating output date use format. Second moment argument is for parsing - however if you omit it then you testDate will cause deprecation warning
Deprecation warning: value provided is not in a recognized RFC2822 or ISO format...
var testDate= "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"
let s= moment(testDate).format('MM/DD/YYYY');
msg.innerText= s;
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>
<div id="msg"></div>
to omit this warning you should provide parsing format
var testDate= "Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)"
let s= moment(testDate, 'ddd MMM D YYYY HH:mm:ss ZZ').format('MM/DD/YYYY');
console.log(s);
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>

You can pass "L" to format method, which handles internationalisation...
moment.locale('en-US');
moment().format("L");
> "06/23/2021"
moment.locale('fr');
moment().format("L");
> "23/06/2021"
Other long date formats (fr locale):
LT : 'HH:mm',
LTS : 'HH:mm:ss',
L : 'DD/MM/YYYY',
LL : 'D MMMM YYYY',
LLL : 'D MMMM YYYY HH:mm',
LLLL : 'dddd D MMMM YYYY HH:mm'
Docs: https://momentjs.com/docs/#/displaying/format/ (see "Localized formats")

To get the current UTC time in YYYY-MM-DD HH:MM:ss.Millisecond with timezone using moment format as below
moment().utc().format('Y-MM-DD HH:mm:ss.SSS Z').
Output
2022-09-20 15:28:39.446 +0000

May be this helps some one who are looking for multiple date formats one after the other by willingly or unexpectedly.
Please find the code:
I am using moment.js format function on a current date as (today is 29-06-2020)
var startDate = moment(new Date()).format('MM/DD/YY'); Result: 06/28/20
what happening is it retains only the year part :20 as "06/28/20", after If I run the statement :
new Date(startDate)
The result is "Mon Jun 28 1920 00:00:00 GMT+0530 (India Standard Time)",
Then, when I use another format on "06/28/20": startDate = moment(startDate ).format('MM-DD-YYYY'); Result: 06-28-1920, in google chrome and firefox browsers it gives correct date on second attempt as: 06-28-2020. But in IE it is having issues, from this I understood we can apply one dateformat on the given date, If we want second date format, it should be apply on the fresh date not on the first date format result.
And also observe that for first time applying 'MM-DD-YYYY' and next 'MM-DD-YY' is working in IE.
For clear understanding please find my question in the link:
Date went wrong when using Momentjs date format in IE 11
