How to Format a Date in Mm/Dd/Yyyy Hh:Mm:Ss Format in JavaScript

How to format a Date in MM/dd/yyyy HH:mm:ss format in JavaScript?

[Addendum 12/2022]: Here's a library to format dates using Intl.DateTimeFormat.

Try something like this

var d = new Date,
    dformat = [d.getMonth()+1,
               d.getDate(),
               d.getFullYear()].join('/')+' '+
              [d.getHours(),
               d.getMinutes(),
               d.getSeconds()].join(':');

If you want leading zero's for values < 10, use this number extension

Number.prototype.padLeft = function(base,chr){
    var  len = (String(base || 10).length - String(this).length)+1;
    return len > 0? new Array(len).join(chr || '0')+this : this;
}
// usage
//=> 3..padLeft() => '03'
//=> 3..padLeft(100,'-') => '--3' 

Applied to the previous code:

var d = new Date,
    dformat = [(d.getMonth()+1).padLeft(),
               d.getDate().padLeft(),
               d.getFullYear()].join('/') +' ' +
              [d.getHours().padLeft(),
               d.getMinutes().padLeft(),
               d.getSeconds().padLeft()].join(':');
//=> dformat => '05/17/2012 10:52:21'

See this code in jsfiddle

[edit 2019] Using ES20xx, you can use a template literal and the new padStart string extension.

const dt = new Date();
const padL = (nr, len = 2, chr = `0`) => `${nr}`.padStart(2, chr);

console.log(`${
    padL(dt.getMonth()+1)}/${
    padL(dt.getDate())}/${
    dt.getFullYear()} ${
    padL(dt.getHours())}:${
    padL(dt.getMinutes())}:${
    padL(dt.getSeconds())}`
);

Convert date object in dd/mm/yyyy hh:mm:ss format

You can fully format the string as mentioned in other posts. But I think your better off using the locale functions in the date object?

var d = new Date("2017-03-16T17:46:53.677"); console.log( d.toLocaleString() ); 

Format JavaScript date as yyyy-mm-dd

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'));

Javascript Date Now (UTC) in yyyy-mm-dd HH:mm:ss format

We should use in-built toISOString function to covert it to ISO date format and remove not required data using string manipulation.

let datenow = new Date();

console.log(datenow); // "2021-07-28T18:11:11.282Z"
console.log(generateDatabaseDateTime(datenow)); // "2021-07-28 14:11:33"

function generateDatabaseDateTime(date) {
  return date.toISOString().replace("T"," ").substring(0, 19);
}

How to format a UTC date as a `YYYY-MM-DD hh:mm:ss` string using NodeJS?

If you're using Node.js, you're sure to have EcmaScript 5, and so Date has a toISOString method. You're asking for a slight modification of ISO8601:

new Date().toISOString()
> '2012-11-04T14:51:06.157Z'

So just cut a few things out, and you're set:

new Date().toISOString().
  replace(/T/, ' ').      // replace T with a space
  replace(/\..+/, '')     // delete the dot and everything after
> '2012-11-04 14:55:45'

Or, in one line: new Date().toISOString().replace(/T/, ' ').replace(/\..+/, '')

ISO8601 is necessarily UTC (also indicated by the trailing Z on the first result), so you get UTC by default (always a good thing).

How to Format Date to Complete YYYY-MM-DD-HH-MM-SS

You can get YYYY-MM-DD-HH-MM-SS format like this:

new Date(d.getTime() - (d.getTimezoneOffset() * 60000)).toISOString().split(".")[0].replace(/[T:]/g, '-')

Explanation:

• .split(".")[0] removes the dot near the end and everything after it.
• .replace(/[T:]/g, '-') changes the T and the colons (:) to dashes.
