Basically all you have to do is include one of the pre-compiled
culture-specific versions instead of the root date.js file and the
Parser will take care of the rest.
For example, we're in Canada and the typical short date format in Canada
is dd/MM/yyyy. We include the date-en-CA.js file into all our web apps.
Example
<script type="text/javascript" src="date-en-CA.js"></script>
All the pre-compiled culture-specific date.js files are located within
the /trunk/build/ directory.
The none minified source CultureInfo files are located within the
/trunk/src/globalization/ directory.
The following "Getting Started with Datejs" blog post contains more
useful information about the CultureInfo files. See

Hope this helps.
