Very simple   var dt new Date  2011 11 30      Date should be in ISO format yyyy MM dd

You definitely want to use the second expression since months in JS are enumerated from 0  Also you may use Date parse method  but it uses different date format  var timestamp   Date parse  quot 11 30 2011 quot    var dateObject   new Date timestamp

The syntax is as follows   new Date year  month    day  hour  minute  second  millisecond      so  Date d   new Date 2011 10 30     is correct  day  hour  minute  second  millisecond are optional   https   developer mozilla org en JavaScript Reference Global Objects Date

Always  for any issue regarding the JavaScript spec in practical  I will highly recommend the Mozilla Developer Network  and their JavaScript reference   As it states in the topic of the Date object about the argument variant you use   new Date year  month  day    hour  minute  second  millisecond      And about the months parameter      month Integer value representing the month  beginning with 0 for January to 11 for December    Clearly  then  you should use the month number 10 for November   P S   The reason why I recommend the MDN is the correctness  good explanation of things  examples  and browser compatibility chart

I can t believe javascript isn t more consistent with parsing dates   And I hear the default when there is no timezone is gonna change from UTC to local -- hope the web is prepared     I prefer to let Javascript do the heavy lifting when it comes to parsing dates   However it would be nice to handle the local timezone issue fairly transparently   With both of these things in mind  here is a function to do it with the current status quo -- and when Javascript changes it will still work but then can be removed  with a little time for people to catch up with older browsers nodejs of course    function strToDate dateStr        var dateTry   new Date dateStr        if   dateTry getTime                  throw new Exception  Bad Date  dateStr      dateStr              var tz   dateStr trim   match   Z     -   d 2       d 2             if   tz                var newTzOffset   dateTry getTimezoneOffset     60          var newSignStr    newTzOffset  gt   0     -                 var newTz   newSignStr     0    Math abs newTzOffset   slice -2      00            dateStr   dateStr trim     newTz          dateTry   new Date dateStr            if   dateTry getTime                          throw new Exception  Bad Date  dateStr      dateStr                        return dateTry      We need a date object regardless  so createone   If there is a timezone  we are done   Otherwise  create a local timezone string using the  hh mm format  more accepted than  hhmm
