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

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

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

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    quot 2020-04-24 quot   var timestamp    new Date myDate

this refactored code will do it  let toTimestamp   strDate   gt  Date parse strDate    this works on all modern browsers except ie8-

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   x000D   x000D  let d   new Date    console log d  d   1   x000D   x000D   x000D

Split the string into its parts and provide them directly to the Date constructor  Update   x000D   x000D  var myDate    26-02-2012   myDate   myDate split  -    var newDate   new Date  myDate 2   myDate 1  - 1  myDate 0    console log newDate getTime     x000D   x000D   x000D

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

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  quot 26-02-2012 quot   myDate myDate split  quot - quot    new Date parseInt myDate 2   10   parseInt myDate 1   10  - 1   parseInt myDate 0    10  getTime     P S  UK locale does not matter here

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
