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?

Split the string into its parts and provide them directly to the Date constructor:

Update:

var myDate = "26-02-2012"; myDate = myDate.split("-"); var newDate = new Date( myDate[2], myDate[1] - 1, myDate[0]); console.log(newDate.getTime());

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')); 

this refactored code will do it

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

this works on all modern browsers except ie8-

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(); 

In case you came here looking for current timestamp

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

or simply

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

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"; myDate=myDate.split("-"); 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

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

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()); } 

The below code will convert the current date into the timestamp.

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

It should have been in this standard date format YYYY-MM-DD, to use below equation. You may have time along with example: 2020-04-24 16:51:56 or 2020-04-24T16:51:56+05:30. It will work fine but date format should like this YYYY-MM-DD only.

var myDate = "2020-04-24"; var timestamp = +new Date(myDate) 

The first answer is fine however Using react typescript would complain because of split('') for me the method tha worked better was.

parseInt((new Date("2021-07-22").getTime() / 1000).toFixed(0)) 

Happy to help.

You can use valueOf method

new Date().valueOf() 

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 

Simply performing some arithmetic on a Date object will return the timestamp as a number. This is useful for compact notation. I find this is the easiest way to remember, as the method also works for converting numbers cast as string types back to number types.

let d = new Date(); console.log(d, d * 1);

This would do the trick if you need to add time also new Date('2021-07-22 07:47:05.842442+00').getTime()

This would also work without Time new Date('2021-07-22 07:47:05.842442+00').getTime()

This would also work but it won't Accept Time new Date('2021/07/22').getTime()

And Lastly if all did not work use this new Date(year, month, day, hours, minutes, seconds, milliseconds)

Note for Month it the count starts at 0 so Jan === 0 and Dec === 11

a picture speaks a thousand words :)

Here I am converting the current date to timestamp and then I take the timestamp and convert it to the current date back, with us showing how to convert date to timestamp and timestamp to date.
