If that number represents milliseconds  use the Date s constructor     var myDate   new Date 1238540400000

You need to extract the number from the string  and pass it into the Date constructor   var x           id   1       start      Date 1238540400000               id   2       start      Date 1238626800000          var myDate   new Date x 0  start match   d    0    1     The parts are   x 0  start                                - get the string from the JSON x 0  start match   d    0                 - extract the numeric part x 0  start match   d    0    1            - convert it to a numeric type new Date x 0  start match   d    0    1   - Create a date object

If you use jQuery  In case you use jQuery on the client side  you may be interested in this blog post that provides code how to globally extend jQuery s   parseJSON   function to automatically convert dates for you   You don t have to change existing code in case of adding this code  It doesn t affect existing calls to   parseJSON    but if you start using   parseJSON data  true   dates in data string will be automatically converted to Javascript dates   It supports Asp net date strings   Date 2934612301   as well as ISO strings 2010-01-01T12 34 56-789Z  The first one is most common for most used back-end web platform  the second one is used by native browser JSON support  as well as other JSON client side libraries like json2 js    Anyway  Head over to blog post to get the code  http   erraticdev blogspot com 2010 12 converting-dates-in-json-strings-using html

I use this   function parseJsonDate jsonDateString       return new Date parseInt jsonDateString replace   Date                 Update 2018   This is an old question  Instead of still using this old non standard serialization format I would recommend to modify the server code to return better format for date  Either an ISO string containing time zone information  or only the milliseconds  If you use only the milliseconds for transport it should be UTC on server and client    2018-07-31T11 56 48Z - ISO string can be parsed using new Date  2018-07-31T11 56 48Z   and obtained from a Date object using dateObject toISOString   1533038208000 - milliseconds since midnight January 1  1970  UTC - can be parsed using new Date 1533038208000  and obtained from a Date object using dateObject getTime
