Javascript Solutions
Solution 1 - Javascript
You can use toLocaleDateString();
let today = new Date().toLocaleDateString('fa-IR');
console.log(today);
fa-IR is for Farsi-Iran,
other dates is as follow:
en-US: For English
hi-IN: For Hindi
...
also you can set options as second argument, for example:
let options = { year: 'numeric', month: 'long', day: 'numeric' };
new Date().toLocaleDateString('fa-IR', options);
and in order to convert characters to Latin digits you can do:
let today = new Date().toLocaleDateString('fa-IR');
today.replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728));

Solution 3 - Javascript
To get it in Persian digits:
new Date().toLocaleDateString('fa-IR');
// ۱۳۹۹/۱/۲۳
To get it in Latin digits:
new Date().toLocaleDateString('fa-IR-u-nu-latn');
// 1399/1/23
Mohsen Mentioned this approach in comments, Thanks to him.
Old approach: To get it in Latin digits:
new Date().toLocaleDateString('fa-IR').replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728));
// 1399/1/23
Solution 4 - Javascript
You can use jalali-moment as easy as the following code
import * as moment from 'jalali-moment';
let persianDate = moment("1989/1/24").locale('fa').format('YYYY/M/D'); // 1367/11/4
Solution 5 - Javascript
You can use the jalaali-js

Solution 6 - Javascript
non of answers in this page worked correct, its working in some cases but not always correct! this is working both side converting methods :
function gregorian_to_jalali(gy,gm,gd){
var g_d_m=[0,31,59,90,120,151,181,212,243,273,304,334];
var jy=(gy<=1600)?0:979;
gy-=(gy<=1600)?621:1600;
var gy2=(gm>2)?(gy+1):gy;
var days=(365*gy) +(parseInt((gy2+3)/4)) -(parseInt((gy2+99)/100))
+(parseInt((gy2+399)/400)) -80 +gd +g_d_m[gm-1];
jy+=33*(parseInt(days/12053));
days%=12053;
jy+=4*(parseInt(days/1461));
days%=1461;
jy+=parseInt((days-1)/365);
if(days > 365)days=(days-1)%365;
var jm=(days < 186)?1+parseInt(days/31):7+parseInt((days-186)/30);
var jd=1+((days < 186)?(days%31):((days-186)%30));
return [jy,jm,jd];
}
function jalali_to_gregorian(jy,jm,jd){
var gy=(jy<=979)?621:1600;
jy-=(jy<=979)?0:979;
var days=(365*jy) +((parseInt(jy/33))*8) +(parseInt(((jy%33)+3)/4))
+78 +jd +((jm<7)?(jm-1)*31:((jm-7)*30)+186);
gy+=400*(parseInt(days/146097));
days%=146097;
if(days > 36524){
gy+=100*(parseInt(--days/36524));
days%=36524;
if(days >= 365)days++;
}
gy+=4*(parseInt((days)/1461));
days%=1461;
gy+=parseInt((days-1)/365);
if(days > 365)days=(days-1)%365;
var gd=days+1;
var sal_a=[0,31,((gy%4==0 && gy%100!=0) || (gy%400==0))?29:28,31,30,31,30,31,31,30,31,30,31];
var gm
for(gm=0;gm<13;gm++){
var v=sal_a[gm];
if(gd <= v)break;
gd-=v;
}
return [gy,gm,gd];
}

You can also check this out: JalaliJSCalendar (github) > JalaliJSCalendar is a JavaScript date-picker and calendar widget based > on "Dynarch DHTML Calendar" from Mihai Bazon. The main difference > between two is that JalaliJSCalendar supports Persian (AKA Hijri > Shamsi) calendar too, which is the official Iranian calendar.
It contains convertor (jalali.js) and HTML datepicker/calendar
Solution 8 - Javascript
Get 'jalali.js' from this link.
If your numbers is in Persian format, at first you have to change them to English format, from this link
var
persianNumbers = [/۰/g, /۱/g, /۲/g, /۳/g, /۴/g, /۵/g, /۶/g, /۷/g, /۸/g, /۹/g],
arabicNumbers = [/٠/g, /١/g, /٢/g, /٣/g, /٤/g, /٥/g, /٦/g, /٧/g, /٨/g, /٩/g],
fixNumbers = function (str) {
if (typeof str === 'string') {
for (var i = 0; i < 10; i++) {
str = str.replace(persianNumbers[i], i).replace(arabicNumbers[i], i);
}
}
return str;
};
and use such as the function 'getGregorian()' below to convert date. For instance I convert '۱۳۹۸/۰۱/۲۴' date:
function getGregorian () {
var date = ("۱۳۹۸/۰۱/۲۴").split('/');
y = Number( fixNumbers(date[0]) );
m = Number( fixNumbers(date[1]) );
d = Number( fixNumbers(date[2] ));
gDate = toGregorian(y, m, d)
gDate = gDate .gy + '/' + gDate .gm + '/' + gDate .gd;
}
Solution 9 - Javascript
function convertDate(stringArg) {
const ETF = '۰۱۲۳۴۵۶۷۸۹';
const ans = g2j(...stringArg.split('/').map(elem => +elem))
.map(elem =>
String(elem)
.split('')
.map(subElem => ETF[+subElem])
.join('')
)
.join('/');
return ans;
}
Solution 10 - Javascript
you also can use the following function that returns all options in a JSON. Read more here.
options:
weekday -> [long | short | narrow]
era -> [long | short | narrow]
timeZoneName -> [long | short]
year -> [numeric | 2-digit]
month -> [numeric | 2-digit | long | short | narrow]
day -> [numeric | 2-digit]
hour -> [numeric | 2-digit]
minute -> [numeric | 2-digit]
second -> [numeric | 2-digit]
to convert digits to Latin digits
.replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728));
function PersianDate(raw_date) {
date = new Date(raw_date);
json_date = {
'weekday': {
'long': date.toLocaleDateString('fa-IR', { weekday: 'long' }),
'short': date.toLocaleDateString('fa-IR', { weekday: 'short' }),
'narrow': date.toLocaleDateString('fa-IR', { weekday: 'narrow' }),
},
'era': {
'long': date.toLocaleDateString('fa-IR', { era: 'long' }),
'short': date.toLocaleDateString('fa-IR', { era: 'short' }),
'narrow': date.toLocaleDateString('fa-IR', { era: 'narrow' }),
},
'timeZoneName': {
'long': date.toLocaleDateString('fa-IR', { timeZoneName: 'long' }),
'short': date.toLocaleDateString('fa-IR', { timeZoneName: 'short' }),
},
'year': {
'numeric': date.toLocaleDateString('fa-IR', { year: 'numeric' }),
'2-digit': date.toLocaleDateString('fa-IR', { year: '2-digit' }),
},
'month': {
'numeric': date.toLocaleDateString('fa-IR', { month: 'numeric' }),
'2-digit': date.toLocaleDateString('fa-IR', { month: '2-digit' }),
'long': date.toLocaleDateString('fa-IR', { month: 'long' }),
'short': date.toLocaleDateString('fa-IR', { month: 'short' }),
'narrow': date.toLocaleDateString('fa-IR', { month: 'narrow' }),
},
'day': {
'numeric': date.toLocaleDateString('fa-IR', { day: 'numeric' }),
'2-digit': date.toLocaleDateString('fa-IR', { day: '2-digit' }),
},
'hour': {
'numeric': date.toLocaleDateString('fa-IR', { hour: 'numeric' }),
'2-digit': date.toLocaleDateString('fa-IR', { hour: '2-digit' }),
},
'minute': {
'numeric': date.toLocaleDateString('fa-IR', { minute: 'numeric' }),
'2-digit': date.toLocaleDateString('fa-IR', { minute: '2-digit' }),
},
'second': {
'numeric': date.toLocaleDateString('fa-IR', { second: 'numeric' }),
'2-digit': date.toLocaleDateString('fa-IR', { second: '2-digit' }),
}
}
return json_date;
}
date = PersianDate(new Date())
// Customize the output format
console.log(date['weekday']['narrow'] + ' ' + date['day']['2-digit'] + ' ' + date['month']['long'] + ' ' + date['year']['numeric']);
// Replatece Farsi digits with Latin ones, e.g. ۲۵ -> 25
console.log(date['day']['2-digit'].replace(/([۰-۹])/g, token => String.fromCharCode(token.charCodeAt(0) - 1728)));

You can install this npm package for node js:
npm i jdate.js
Or import this script for javascript and html:
<script src="https://cdn.jsdelivr.net/npm/jdate.js"></script>
Usage:
var date = new Date();
console.log( date.echoFa() );
console.log( date.echo() );
console.log( date );

<script src="https://cdn.jsdelivr.net/npm/jdate.js"></script>
<script type="text/javascript">
(function() {
var date = new Date();
console.log("Normal format: " + date.echo("Y/m/d"));
console.log("Jalali format: " + date.echoFa("Y/m/d"));
})();
</script>
