Format JavaScript date without localizing

Question

Let's say I have the following date as a string:

2022-01-05

I'd like to convert this to the following format:

Jan 5, 2022

I've tried using the following code:

const shortDateFormat = new Intl.DateTimeFormat("en-US", {
  dateStyle: "medium",
});
shortDateFormat.format(new Date("2022-01-05"));

But I'm getting the following result:

Jan 4, 2022

Looks like the problem is a localization issue. I'm in NY so creating a new date creates the wrong datetime:

new Date("2022-01-05")
# Tue Jan 04 2022 19:00:00 GMT-0500 (Eastern Standard Time)

How can I format the date without worrying about localization issues? Note:

These dates are in UTC and my frontend displays this fact.

Is it will be ok if I manually do it like from 'Wed Jan 5 2022' to 'Jan 5, 2022' ? — Kazi Tajnur Islam

Add the UTC time zone to the DateTimeFormat options.

Note: Etc/UTC is the canonical time zone, there are several alternatives, e.g. just UTC (used in the snippet), Etc/Universal, Etc/GMT[+0] or Etc/Zulu. See this list.

const shortDateFormat = new Intl.DateTimeFormat("en-US", {
  dateStyle: "medium",
  timeZone: "UCT",
});
const dateStr = `2022-01-05`;
console.log(shortDateFormat
  .format(new Date(dateStr)));

Doesn't work for me. Still getting Jan 4, 2022

Passing timeZone: "UTC" works. Please update and I'll accept this answer.

This can solve your problem.

const event = new Date(Date.UTC(2012, 11, 20, 3, 0, 0));
const options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };

console.log(event.toLocaleDateString('de-DE', options));
// expected output (varies according to local timezone): Donnerstag, 20. Dezember 2012

console.log(event.toLocaleDateString('ar-EG', options));
// expected output (varies according to local timezone): الخميس، ٢٠ ديسمبر، ٢٠١٢

console.log(event.toLocaleDateString(undefined, options));
// expected output (varies according to local timezone and default locale): Thursday, December 20, 2012

More details here

For the options, you can pass timezone this way:

new Date().toLocaleDateString("en-US", {timeZone: "America/New_York"})

Or

const options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric', timeZone: "America/New_York" };

You can get the current timezone on your browser this way:

const timezone = Intl.DateTimeFormat().resolvedOptions().timeZone;
//expected output: "America/Los_Angeles" (if you are in PST)

Well, you are facing a localization issue. I think a small tricks will help you to avoid the problem.

Let we have a date string as '2022-01-05'. We will convert it to an array of numbers, for the string it will be [2022, 1, 5]. Then we will pass the numbers as the parameters of the Date() constructor along with the hours, minutes, and seconds. Thus it will be parse as a UTC date string and your problem will be solved. Let's do this:

let dateString = "2022-01-05";
let dateNums = dateString.split('-').map(str => parseInt(str));

const shortDateFormat = new Intl.DateTimeFormat("en-US", {
  dateStyle: "medium",
});
shortDateFormat.format(new Date(dateNums[0], dateNums[1] - 1, dateNums[2], 0, 0, 0));
// 'Jan 5, 2022'

Here, we did dateNums[1] - 1 because we have to pass month as an index thus we decrement it. We passed parameters into the Date() constructor as Date(year, monthIndex, day, hours, minutes, seconds)

I think your problem is solved :)
