title: XDate vs Datejs
body: <p>Has anyone used <a href="http://arshaw.com/xdate/" rel="nofollow">XDate</a> or <a href="http://datejs.com" rel="nofollow">datejs</a>?  Both of them seem to have been out of development for a while, and neither of them have a good release it seems (datejs is "pre-alpha" and xdate is version 0.7).</p>
  
  <p>I'm needing to do some javascript date manipulation (strings -> date objects, date objects -> strings, adding time/days/months to date objects, and calculating the difference in dates).  All of that is possible with the native Javacript Date Object, obviously, but it's so painful - I was hoping someone would have a suggestion on a better API.  These two libraries seem okay, but their age and lack of development history concerns me.</p>
  
  <p>Does anyone have experience with either or both of these libraries?  Or maybe a better alternative that will suit my needs above?</p>
