<ListBox.Template>
    <ControlTemplate TargetType="{x:Type ListBox}">
        <blendables:TimelinePanel IsItemsHost="True" 
            UnitSize="{StaticResource unitSize}" 
            UnitTimeSpan="1"

            EndDate="12/31/2009" 
            />
     </ControlTemplate>
</ListBox.Template>

You can use data binding to change them dynamically.
