People also ask

How do I get a locale date?

Use the toLocaleString() method to get a date and time in the user's locale format, e.g. date. toLocaleString() . The toLocaleString method returns a string representing the given date according to language-specific conventions.

What does the toLocaleString () method do in JS?

The toLocaleString() method returns a string with a language-sensitive representation of this date. In implementations with Intl. DateTimeFormat API support, this method simply calls Intl. DateTimeFormat .

console.log(navigator.language,getLocaleDateString());

I think this is the best way to do it...

    var date = new Date();

    var options = {
        weekday: "short",
        year: "numeric",
        month: "2-digit",
        day: "numeric"
    };

console.log(
    date.toLocaleDateString("en", options) //en is language option, you may specify..
);

More Options and their examples....

Can't be done.

Cross-browser JavaScript has no way to use the actual short date format selected by the user on platforms that offer such regional customization. Besides, JavaScript has huge holes where any sort of formatting is concerned. Look how much hassle zero-padding is!

You can go to great lengths to obtain the language setting, and get the typical format for that locale. That's a lot of work when you don't even know if it's the correct locale (I'd bet that international language headers are often incorrect or not specific enough), or if the user has customized the format to something else.

You can try using client VBScript (which has functions for all of these regional formatting permutations), but that's not a good idea because it's a dying (dead?) IE-specific technology.

You can also try using Java/Flash/Silverlight to dig up the format. This is also a great deal of extra work, but may have the best chance for success. You'd want to cache it for the session to minimize the overhead.

Hopefully the HTML5 <time> element will provide some relief for i18n date/time display.


If your question about <input type="date"> field, here is script for getting filed value="" attribute:

(new Date()).toISOString().split('T')[0]

You can use the Intl object (ecma-402) to get data-date-pattern="":

(new Intl.DateTimeFormat()).resolved.pattern // "M/d/y" for "en-US" in Google Chrome

And finnaly, to format date in current l10n, data-date="":

(new Intl.DateTimeFormat()).format(new Date());

https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/DateTimeFormat

The Intl.DateTimeFormat object is a constructor for objects that enable language sensitive date and time formatting.

var date = new Date(2014, 11, 31, 12, 30, 0);

var formatter = new Intl.DateTimeFormat("ru");
console.log( formatter.format(date) ); // 31.12.2014

var formatter = new Intl.DateTimeFormat("en-US");

console.log(formatter.format(date)); // 12/31/2014

format of your current zone :

console.log(new Intl.DateTimeFormat(Intl.DateTimeFormat().resolvedOptions().locale).
format(new Date()))

function getDatePattern(locale) {
  // expected style = year: 2010, month: 12, day: 31
  var options = { year: "numeric", month: "2-digit", day: "2-digit" };

  // formatToParts() returns array of object breaking down the locales dateformat
  // [ 
  //  {type: "month", value: "03"},
  //  {type: "literal", value: "/"},
  //  {type: "day", value: "30"},
  //  {type: "literal", value: "/"},
  //  {type: "year", value: "2021"},
  // ]
  var formatter = new Intl.DateTimeFormat(locale, options).formatToParts();

  return formatter.map(function(e) {
      switch(e.type) {
        case 'month':
          return 'MM'; break;
        case 'day':
          return 'DD'; break;
        case 'year':
          return 'YYYY'; break;
        default: 
          return e.value;
      };
    }).join('');
}

// "YYYY/MM/DD"
console.log(getDatePattern('en'));
// "YYYY. MM. DD."
console.log(getDatePattern('ko'));
