How to get year/month/day from a date object?

alert(dateObj) gives Wed Dec 30 2009 00:00:00 GMT+0800

How to get date in format 2009/12/30?

var dateObj = new Date();
var month = dateObj.getUTCMonth() + 1; //months from 1-12
var day = dateObj.getUTCDate();
var year = dateObj.getUTCFullYear();

newdate = year + "/" + month + "/" + day;

or you can set new date and give the above values

new Date().toISOString()
"2016-02-18T23:59:48.039Z"
new Date().toISOString().split('T')[0];
"2016-02-18"
new Date().toISOString().replace('-', '/').split('T')[0].replace('-', '/');
"2016/02/18"

new Date().toLocaleString().split(',')[0]
"2/18/2016"

var dt = new Date();

dt.getFullYear() + "/" + (dt.getMonth() + 1) + "/" + dt.getDate();

Since month index are 0 based you have to increment it by 1.

Edit

For a complete list of date object functions see

Date

getMonth()

Returns the month (0-11) in the specified date according to local time.

getUTCMonth()

Returns the month (0-11) in the specified date according to universal time.

Why not using the method toISOString() with slice or simply toLocaleDateString()?

Beware that the timezone returned by toISOString is always zero UTC offset, whereas in toLocaleDateString it is the user agent's timezone.

Check here:

const d = new Date() // today, now

// Timezone zero UTC offset
console.log(d.toISOString().slice(0, 10)) // YYYY-MM-DD

// Timezone of User Agent
console.log(d.toLocaleDateString('en-CA')) // YYYY-MM-DD
console.log(d.toLocaleDateString('en-US')) // M/D/YYYY
console.log(d.toLocaleDateString('de-DE')) // D.M.YYYY
console.log(d.toLocaleDateString('pt-PT')) // DD/MM/YYYY

I would suggest you to use Moment.js http://momentjs.com/

Then you can do:

moment(new Date()).format("YYYY/MM/DD");

Note: you don't actualy need to add new Date() if you want the current TimeDate, I only added it as a reference that you can pass a date object to it. for the current TimeDate this also works:

moment().format("YYYY/MM/DD");

2021 ANSWER

You can use the native .toLocaleDateString() function which supports several useful params like locale (to select a format like MM/DD/YYYY or YYYY/MM/DD), timezone (to convert the date) and formats details options (eg: 1 vs 01 vs January).

Examples

new Date().toLocaleDateString() // 8/19/2020

new Date().toLocaleDateString('en-US', {year: 'numeric', month: '2-digit', day: '2-digit'}); // 08/19/2020 (month and day with two digits)

new Date().toLocaleDateString('en-ZA'); // 2020/08/19 (year/month/day) notice the different locale

new Date().toLocaleDateString('en-CA'); // 2020-08-19 (year-month-day) notice the different locale

new Date().toLocaleString("en-US", {timeZone: "America/New_York"}); // 8/19/2020, 9:29:51 AM. (date and time in a specific timezone)

new Date().toLocaleString("en-US", {hour: '2-digit', hour12: false, timeZone: "America/New_York"});  // 09 (just the hour)

Notice that sometimes to output a date in your specific desire format, you have to find a compatible locale with that format. You can find the locale examples here: https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_tolocalestring_date_all

Please notice that locale just change the format, if you want to transform a specific date to a specific country or city time equivalent then you need to use the timezone param.

var date = new Date().toLocaleDateString()
"12/30/2009"

info

If a 2 digit month and date is desired (2016/01/01 vs 2016/1/1)

code

var dateObj = new Date();
var month = ('0' + (dateObj.getMonth() + 1)).slice(-2);
var date = ('0' + dateObj.getDate()).slice(-2);
var year = dateObj.getFullYear();
var shortDate = year + '/' + month + '/' + date;
alert(shortDate);

output

2016/10/06

To learn more about .slice the try it yourself editor at w3schools helped me understand better how to use it.

Use the Date get methods.

http://www.tizag.com/javascriptT/javascriptdate.php

http://www.htmlgoodies.com/beyond/javascript/article.php/3470841

var dateobj= new Date() ;
var month = dateobj.getMonth() + 1;
var day = dateobj.getDate() ;
var year = dateobj.getFullYear();

Nice formatting add-in: http://blog.stevenlevithan.com/archives/date-time-format.

With that you could write:

var now = new Date();
now.format("yyyy/mm/dd");

let dateObj = new Date();

let myDate = (dateObj.getUTCFullYear()) + "/" + (dateObj.getMonth() + 1)+ "/" + (dateObj.getUTCDate());

For reference you can see the below details

new Date().getDate()          // Return the day as a number (1-31)
new Date().getDay()           // Return the weekday as a number (0-6)
new Date().getFullYear()      // Return the four digit year (yyyy)
new Date().getHours()         // Return the hour (0-23)
new Date().getMilliseconds()  // Return the milliseconds (0-999)
new Date().getMinutes()       // Return the minutes (0-59)
new Date().getMonth()         // Return the month (0-11)
new Date().getSeconds()       // Return the seconds (0-59)
new Date().getTime()          // Return the time (milliseconds since January 1, 1970)

let dateObj = new Date();

let myDate = (dateObj.getUTCFullYear()) + "/" + (dateObj.getMonth() + 1)+ "/" + (dateObj.getUTCDate());

console.log(myDate)

EUROPE (ENGLISH/SPANISH) FORMAT
I you need to get the current day too, you can use this one.

function getFormattedDate(today) 
{
    var week = new Array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday');
    var day  = week[today.getDay()];
    var dd   = today.getDate();
    var mm   = today.getMonth()+1; //January is 0!
    var yyyy = today.getFullYear();
    var hour = today.getHours();
    var minu = today.getMinutes();
    			
    if(dd<10)  { dd='0'+dd } 
    if(mm<10)  { mm='0'+mm } 
    if(minu<10){ minu='0'+minu } 
    			    
    return day+' - '+dd+'/'+mm+'/'+yyyy+' '+hour+':'+minu;
}

var date = new Date();
var text = getFormattedDate(date);

*For Spanish format, just translate the WEEK variable.

var week = new Array('Domingo', 'Lunes', 'Martes', 'Miércoles', 'Jueves', 'Viernes', 'Sábado');

Output: Monday - 16/11/2015 14:24

With the accepted answer, January 1st would be displayed like this: 2017/1/1.

If you prefer 2017/01/01, you can use:

var dt = new Date();
var date = dt.getFullYear() + '/' + (((dt.getMonth() + 1) < 10) ? '0' : '') + (dt.getMonth() + 1) + '/' + ((dt.getDate() < 10) ? '0' : '') + dt.getDate();

Here is a cleaner way getting Year/Month/Day with template literals:

var date = new Date();
var formattedDate = `${date.getFullYear()}/${(date.getMonth() + 1)}/${date.getDate()}`;
console.log(formattedDate);

> It's Dynamic It will collect the language from user's browser setting

> Use minutes and hour property in the option object to work with them.. > You can use long value to represent month like Augest 23 etc...

function getDate(){
 const now = new Date()
 const option = {
  day: 'numeric',
  month: 'numeric',
  year: 'numeric'
 }
 const local = navigator.language
 labelDate.textContent = `${new 
 Intl.DateTimeFormat(local,option).format(now)}`
}
getDate()

You can simply use This one line code to get date in year-month-date format

var date = new Date().getFullYear() + "-" + new Date().getMonth() + 1 + "-" + new Date().getDate();

I am using this which works if you pass it a date obj or js timestamp:

getHumanReadableDate: function(date) {
	if (date instanceof Date) {
		 return date.getDate() + "/" + (date.getMonth() + 1) + "/" + date.getFullYear();
	} else if (isFinite(date)) {//timestamp
		var d = new Date();
		d.setTime(date);
		return this.getHumanReadableDate(d);
	}
}

ES2018 introduced regex capture groups which you can use to catch day, month and year:

const REGEX = /(?<year>[0-9]{4})-(?<month>[0-9]{2})-(?<day>[0-9]{2});
const results = REGEX.exec('2018-07-12');
console.log(results.groups.year);
console.log(results.groups.month);
console.log(results.groups.day);

Advantage of this approach is possiblity to catch day, month, year for non-standard string date formats.
