prettydate.js
Small lib for formatting dates. This is based on the library from John Resig called Javascript Pretty Dates. http://ejohn.org/blog/javascript-pretty-date/
Why Another Pretty Date Lib
Found a bug in the original code, where it will not work in safari browsers (iOS and OSX).
The goal is to develop something light weight that covers the basic functions of formatting dates. If you need something more advance, consider moments.js https://github.com/moment/moment/.
Usage
prettyDate.prettify('2014-03-20T03:24:00Z');
If date provided is more than 31 days long from now, then it will return undefined.
