Your plugin looks perfect for what I need to for my site. I need to put our cricket fixtures on my site and a calendar would seem the best way.
I did this one my previous site (not WordPress) and the issue was the calendar would always start on the date you were looking at the page. This was great for this season, but when you went back to the 2010 season you have to click back 3 years. Is it possible to code a starting date?
