I was working on a project which required a simple calendar with inline edit. The calendar is for a school which marks if the day is working or not, and the comment (told ya, its very simple). Needs PHP, jQuery, jQuery jEditable plugin and a MySQL table to store the data.

The demo is here. If anyone is interested in the code, drop a comment.

P.S: Yea I suck at CSS. If anyone does a better job, please let me know.
