According to my web designer experience, one of the most common requests from clients when it comes to Wordpress personalization, is to add a basic event calendar to their website.

Finding a good place to position a big table like a calendar within your Wordpress template is always a taught work. In addition, the tag itself is often quite difficult to style in a good way

Calendar is a Javascript class that adds accessible and unobtrusive date-pickers to your form elements. This class is a compilation of many date-pickers I have implemented over the years and has been completely re-written for Mootools. I have tried to include all the features that have been most useful while streamlining the class itself to keep it as small as possible. Use the links below to see what features are available in Calendar and how it might enhance the accessibility, usability and validation of form elements on your website.
