Excellent plugin!

I needed a simple calendar to show availability for seminars. This plugin does what I wanted very efficiently. It’s easy to customize, you can show multiple months, and it has a very nice user interface. You can edit date ranges at once to quickly edit the availability of multiple days or you can edit each one individually. The customizable legend makes this very flexible – you can add your own color coding and legend items. The support is awesome – fast and helpful responses.
