Behind The Framework-Javascript Date Object
Lets take a MOMENT to learn the native Javascript Date object. The Date() constructor can be called with two or more arguments, in which case they are interpreted as the year, month, day, hour, minute, second, and millisecond, respectively, in local time. Date.UTC() works similarly, but it interprets the components as UTC time and also accepts a single argument representing the year.

May 8, 2025 - ISO 8601 is the most common for APIs and databases because it is standardized and easily parsed by new Date(). Since they’re just raw numbers, Unix timestamps are great for calculations and comparisons. RFC 2822 is mostly seen in older systems or emails. Regardless of the format you start with, JavaScript’s Date object is your primary tool for interpreting and working with these values.

r/javascript on Reddit: A simple guide to JavaScript Dates
July 9, 2018 - YYYY-MM-DD is the ISO-8601 standard for dates, so it's more natural to use UTC (and hence midnight UTC). Yes it is a common local format as well, but programmers are going to want the technical standard somewhere.

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
