Multiple dates with different classes

We're not using any UI styling for this example

Different classes set on dates, all data stored in arrays

["14-11-2014","16-11-2014"]; //these dates have less than 5 events

["18-11-2014","20-11-2014"]; //these dates have 5 to 20 events

["22-11-2014","24-11-2014"]; //these dates have more than 20 events
