The Date object handles 8601 as it s first parameter    x000D   x000D  var d   new Date  2014-04-07T13 58 10 104Z    x000D  console log d toString     x000D   x000D   x000D

Maybe  you can use moment js which in my opinion is the best JavaScript library for parsing  formatting and working with dates client-side  You could use something like    x000D   x000D  var momentDate   moment  1890-09-30T23 59 59 01 16 20    YYYY-MM-DDTHH mm ss -HH mm ss    x000D  var jsDate   momentDate toDate    x000D   x000D     Now  you can run any JavaScript Date method x000D   x000D  jsDate toLocaleString    x000D   x000D   x000D    The advantage of using a library like moment js is that your code will work perfectly even in legacy browsers like IE 8    Here is the documenation about parsing methods  https   momentjs com docs   parsing

If you want to keep it simple  this should suffice   function parseIsoDatetime dtstr        var dt   dtstr split     T-    map parseFloat       return new Date dt 0   dt 1  - 1  dt 2   dt 3     0  dt 4     0  dt 5     0  0       note parseFloat is must  parseInt doesn t always work  Map requires IE9 or later   Works for formats     2014-12-28 15 30 30 2014-12-28T15 30 30 2014-12-28   Not valid for timezones  see other answers about those

According to MSDN  the JavaScript Date object does not provide any specific date formatting methods  as you may see with other programming languages    However  you can use a few of the Date methods and formatting to accomplish your goal   function dateToString  date         Use an array to format the month numbers   var months          January        February        March                      Use an object to format the timezone identifiers   var timeZones          360    EST                   var month   months date getMonth       var day   date getDate      var year   date getFullYear       var hours   date getHours      var minutes   date getMinutes      var time    hours  gt  11    hours - 11     hours   1           minutes    hours  gt  11    PM     AM      var timezone   timeZones date getTimezoneOffset           Returns formatted date as string  e g  January 28  2011 - 7 30PM EST    return month         day          year     -     time         timezone     var date   new Date  2011-01-28T19 30 00-05 00     alert dateToString date      You could even take it one step further and override the Date toString   method   function dateToString         No date argument this time      Use an array to format the month numbers   var months          January        February        March                      Use an object to format the timezone identifiers   var timeZones          360    EST                   var month   months  this  getMonth       var day    this  getDate      var year    this  getFullYear       var hours    this  getHours      var minutes    this  getMinutes      var time    hours  gt  11    hours - 11     hours   1           minutes    hours  gt  11    PM     AM      var timezone   timeZones  this  getTimezoneOffset           Returns formatted date as string  e g  January 28  2011 - 7 30PM EST    return month         day          year     -     time         timezone     var date   new Date  2011-01-28T19 30 00-05 00    Date prototype toString   dateToString   alert date toString
