Regional-based Date Formatting in MomentJs

Solution 1:
Utilizing the moment timezone package enables you to accomplish the following – specify the desired date format within format() to obtain the date in that specific format.
Solution 2:
Regarding your second question, it’s uncertain if you’re proceeding in the correct direction. In any case, ISO8601 format date is the predominant standard for modern software’s date formats.


Question:

Given a User’s location, specifically in London or elsewhere, the desired date format should be DD/MM/YYYY. Is it feasible to achieve this using moment? Can
moment format
dynamically adjust the date based on the User’s timezone?

Please note that I am aware that we can determine the user’s locale, but I’m wondering if we can achieve the same result by using the timezone. Am I on the correct path?

When using the ‘.format(‘L’)’ function, the formatting will be in “DD/MM/YYYY”, but it is dependent on the locale rather than the timezone.


Solution 1:

To achieve that, the moment timezone package can be utilized.

Afterward, you will have the capability to perform the following actions –

var moment = require('moment-timezone');
moment().tz("America/Los_Angeles").format();

In order to obtain the date in a particular format, you would indicate that format within the format() function.

moment().tz("America/Los_Angeles").format('DD/MM/YYYY');


Solution 2:


To address your second inquiry, I’m unsure if you’re heading in the correct path. Although countries may share the same timezone, they can have distinct date formats. For instance, Montreal, being in the same timezone as New York (Eastern Daylight Time), has a different date format, which is YYYY-MM-DD. When utilizing moment timezone, it is possible to obtain various outcomes.

var montreal = moment.tz("2014-06-01 12:00", "America/Montreal");
var newYork = moment.tz("2014-06-01 12:00", "America/New_York");
console.log(montreal.format('L')); // This should be '2014-06-01' but produces '06/01/2014'
console.log(newYork.format('L'));


Solution 3:


A locale does not automatically have a format associated with it, apart from
time zone
.

To determine the format based on the time zone, obtain the time zone using

getTimezoneOffset

and utilize predefined constants to obtain the desired format for the specific time zone.

const zoneFormats = {
   1: "dd/mm/yyyy"
   2: "mm/dd/yyyy"
}

Then, adjust your time format based on the selected formatter through the constant.

var format = zoneFormats[new Date().getTimezoneOffset()];
moment().format(format || 'yyyy-mm-dd');
