How do you convert a Unix timestamp to Jalali/Shamsi/Persian format?

I'm developing a web App and I have a unix timeStamp. I need to convert a unix date format to Jalali/Persian/Shamsi Calendar by using jQuery selectors and then convert it by using javascript library.
Something Like below code to convert Unix-Date to Jalali-Date:

<html>
  <head>
  <meta charset="utf-8">
  </head>

  <body>
  <div class="Unix-Date">1494259627</div> <!-- Unix equal of 1396/2/18 -->
  <div class="Jalali-Date"></div>

  <script src="jquery.js"></script>
  <script src="external-library.js"></script>
  <script>
  $(document).ready(function() {
  var UnixValue;
  var JalaliValue;
  UnixValue = $(".Unix-Date").html();
  JalaliValue = new JalaliExternalFunction(UnixValue);
  $(".Jalali-Date").text(JalaliValue);
  });
  </script>
  </body>
</html>

I searched but didn't found any good library. Do you know a reliable and good library for converting (or creating dates in Jalali format from a unix timeStamp). I don't need your implementation or an algorithm, cause this issue is too buggy and has a lot of rules, I need a reliable solution.

Thank

I would suggest using moment.js (https://momentjs.com/) which is reliable JavaScript Time library that allows you to format your timestamp in JavaScript. Below is an example of how you can parse a timestamp and format it to whatever you want using it.

//formatting Unix timestamp.
var date = moment.unix(value).format("MM/DD/YYYY");

You also tagged localization which can be done by using;

 var localeDate = moment(date).locale("LT");

More examples can be found on there website.

This in conjunction with https://www.npmjs.com/package/jalali-date will get you your jalali date.

There is a moment.js extension for Persian here also https://www.npmjs.com/package/moment-jalaali (From moment to Jalali)

Another Jalali conversion library https://www.npmjs.com/package/jalaali-js (To Jalai)

An example fiddle using moment.js Jalali conversion from Unix Timestamp https://jsfiddle.net/uw82ozpd/9/

Relevant code snippet with comments:

var UnixValue;
var JalaliValue;

$(document).ready(function() {

//get the Unix Date from HTML
var UnixValue = $(".Unix-Date").html();

//Get a moment timestamp in the format simmilar to our next conversion
var date = moment.unix(UnixValue).format("MM/DD/YY");

//Convert from normal moment to our jalali moment exstension using j's as below
var JalaliValue = moment(date).format('jYYYY/jM/jD');

$(".Jalali-Date").text(JalaliValue);

});

you can use toLocalDateString()

let mydate = new Date(timestamp);
let mypersiandate = mydate.toLocaleDateString('fa-IR');
console.log(mypersiandate);
