How to convert date to timestamp?

I want to convert date to timestamp, my input is 26-02-2012. I used

new Date(myDate).getTime();

It says NaN.. Can any one tell how to convert this?


var myDate="26-02-2012";
var newDate=myDate[1]+","+myDate[0]+","+myDate[2];
alert(new Date(newDate).getTime());? //will alert 1330192800000


var myDate="26-02-2012";
var newDate=myDate[1]+"/"+myDate[0]+"/"+myDate[2];
alert(new Date(newDate).getTime()); //will alert 1330210800000

DEMO (Tested in Chrome, FF, Opera, IE, and Safari).


Try this function, it uses the Date.parse() method and doesn't require any custom logic:

function toTimestamp(strDate){
   var datum = Date.parse(strDate);
   return datum/1000;
alert(toTimestamp('02/13/2009 23:31:30'));
var dtstr = "26-02-2012";
new Date(dtstr.split("-").reverse().join("-")).getTime();

this refactored code will do it

let toTimestamp = strDate => Date.parse(strDate)

this works on all modern browsers except ie8-


You need just to reverse your date digit and change - with ,:

 new Date(2012,01,26).getTime(); // 02 becomes 01 because getMonth() method returns the month (from 0 to 11)

In your case:

 var myDate="26-02-2012";
 new Date(parseInt(myDate[2], 10), parseInt(myDate[1], 10) - 1 , parseInt(myDate[0]), 10).getTime();

P.S. UK locale does not matter here.


To convert (ISO) date to Unix timestamp, I ended up with a timestamp 3 characters longer than needed so my year was somewhere around 50k...

I had to devide it by 1000: new Date('2012-02-26').getTime() / 1000


Your string isn't in a format that the Date object is specified to handle. You'll have to parse it yourself, use a date parsing library like MomentJS or the older (and not currently maintained, as far as I can tell) DateJS, or massage it into the correct format (e.g., 2012-02-29) before asking Date to parse it.

Why you're getting NaN: When you ask new Date(...) to handle an invalid string, it returns a Date object which is set to an invalid date (new Date("29-02-2012").toString() returns "Invalid date"). Calling getTime() on a date object in this state returns NaN.

 * Date to timestamp
 * @param  string template
 * @param  string date
 * @return string
 * @example         datetotime("d-m-Y", "26-02-2012") return 1330207200000
function datetotime(template, date){
    date = date.split( template[1] );
    template = template.split( template[1] );
    date = date[ template.indexOf('m') ]
        + "/" + date[ template.indexOf('d') ]
        + "/" + date[ template.indexOf('Y') ];

    return (new Date(date).getTime());

Incase you came here looking for current timestamp

  var date      = new Date();
  var timestamp = date.getTime();


new Date().getTime();
//console.log(new Date().getTime());

Answers have been provided by other developers but in my own way, you can do this on the fly without creating any user defined function as follows:

var timestamp = Date.parse("26-02-2012".split('-').reverse().join('-'));
alert(timestamp); // returns 1330214400000

There are two problems here. First, you can only call getTime on an instance of the date. You need to wrap new Date in brackets or assign it to variable.

Second, you need to pass it a string in a proper format.

Working example:

(new Date("2012-02-26")).getTime();
function getTimeStamp() {
       var now = new Date();
       return ((now.getMonth() + 1) + '/' + (now.getDate()) + '/' + now.getFullYear() + " " + now.getHours() + ':'
                     + ((now.getMinutes() < 10) ? ("0" + now.getMinutes()) : (now.getMinutes())) + ':' + ((now.getSeconds() < 10) ? ("0" + now
                     .getSeconds()) : (now.getSeconds())));

For those who wants to have readable timestamp in format of, yyyymmddHHMMSS

> (new Date()).toISOString().replace(/[^\d]/g,'')              // "20190220044724404"
> (new Date()).toISOString().replace(/[^\d]/g,'').slice(0, -3) // "20190220044724"
> (new Date()).toISOString().replace(/[^\d]/g,'').slice(0, -9) // "20190220"

Usage example: a backup file extension. /my/path/my.file.js.20190220

var currentTimeStamp = Date.parse(new Date());
