Have been searching for a calendar with all the features present in the WordPress Spider Calendar. The straight foward input, format customizations have proven themselves for a client with many events and special dates, often updated or with detail changes. Integrated perfectly.

Spider Calendar provides exactly the functionality I was looking for. I used it on a client’s website as a replacement for a competing calendar (which I had used on my own website, but had to hack the code). I particularly like the ease of adding or modifying calendar entries, especially as I will have to teach other people how to do this.
Support is superb!

Have been using this product for a while and really like it. One of the best calendar programs out there for WP!
