Just leverage the built-in toISOString method that brings your date to the ISO 8601 format:
let yourDate = new Date()
yourDate.toISOString().split('T')[0]
Where yourDate is your date object.
Edit: @exbuddha wrote this to handle time zone in the comments:
const offset = yourDate.getTimezoneOffset()
yourDate = new Date(yourDate.getTime() - (offset*60*1000))
return yourDate.toISOString().split('T')[0]

You can do:
function formatDate(date) {
var d = new Date(date),
month = '' + (d.getMonth() + 1),
day = '' + d.getDate(),
year = d.getFullYear();
if (month.length < 2)
month = '0' + month;
if (day.length < 2)
day = '0' + day;
return [year, month, day].join('-');
}
console.log(formatDate('Sun May 11,2014'));
Usage example:
console.log(formatDate('Sun May 11,2014'));
Output:
2014-05-11

I'm going insane. I had this feature working perfectly. Took 2 weeks vacation. I come back and it's broken.
I know y'all will say this is impossible, but I was getting that format by using `date.toLocaleDateString('en-CA')`. I know the spec says that format is "dd/MM/yyyy", which isn't what I want, but I was giving me the format in the title, I swear to God.
This is such a stupid little thing but I've already spent hours on SO. It's just endless threads about people confused about datetimes and the differences between timezones and offsets and no one's talking about this silly little thing.
I have my new date: Wed Feb 08 2023 00:00:00 GMT-0500 (Eastern Standard Time)
I just need a simple operation to flip the string around so it becomes 2023-03-08
That is it. Please help
p.s. the date is always set to midnight user local time so offset can be ignored. Whatever day they're experiencing is the day to be formatted. Thank you
I hope this is what you want:
const today = new Date();
const yyyy = today.getFullYear();
let mm = today.getMonth() + 1; // Months start at 0!
let dd = today.getDate();
if (dd < 10) dd = '0' + dd;
if (mm < 10) mm = '0' + mm;
const formattedToday = dd + '/' + mm + '/' + yyyy;
document.getElementById('DATE').value = formattedToday;
How do I get the current date in JavaScript?
I honestly suggest that you use moment.js. Just download moment.min.js and then use this snippet to get your date in whatever format you want:
<script>
$(document).ready(function() {
// set an element
$("#date").val( moment().format('MMM D, YYYY') );
// set a variable
var today = moment().format('D MMM, YYYY');
});
</script>
Use following chart for date formats:

Just use the built-in .toISOString() method like so: toISOString().split('T')[0]. Simple, clean and all in a single line.
var date = (new Date()).toISOString().split('T')[0];
document.getElementById('date').innerHTML = date;
<div id="date"></div>
Please note that the timezone of the formatted string is UTC rather than local time.
One line solution for 'YYYY-MM-DD'
new Date().toLocaleDateString("fr-CA", {year:"numeric", month: "2-digit", day:"2-digit"})
// output on New Years Eve 2023: '2023-12-31'
