MiG Calendar is a Java component that displays a visually very advanced calendar. What really differs this component from others is the extreme flexibility built in from the start, especially when it comes to the visual presentation and flexible layout. Everything visual is drawn in layers, called decorators, and they can easily be rearranged, modified, extended or recreated.

When we say extremely flexible, we really mean Extremely Flexible. The main reasons for this is:

• The visual style and layout are both theamable and the component includes a visual Theme Editor to edit and create Themes.
• Almost every aspect of the component can be "overridden" to implement totally new behaviors or visual effects.
• Overridable/exchangeable renderers are used extensively for creating the visuals. Those renderers are easy to extend or rewrite.
• Interfaces and abstract base classes have been used to the same degree as in Swing.
• MiG Calendar can be used as a date picker in a Combo Box, a generic calendar view, advanced date spinner(s) including support for date ranges or an API used for advanced date handling.

The component follows the MVC (Model View Controller) paradigm. This ensures that the decoupling of the visual part from the data. An example of this is the possibility to have many views of activities, say a day and a week view, and when you move or resize an activity in on view, the other view(s) are updated live.
