Vaadin Calendar is for visualizing events in a calendar. Calendar events can be visualized in the variable length view depending on the start and end dates.
You can set the viewable date range with the setStartDate(Date) and setEndDate(Date) methods. Calendar has a default date range of one week
Calendar has two kind of views: monthly and weekly view
If date range is seven days or shorter, the weekly view is used.
Calendar queries its events by using a CalendarEventProvider. By default, a BasicEventProvider is used.

```
    Sets a container as a data source for the events in the calendar. Equivalent for doing Calendar.setEventProvider(new ContainerEventProvider(container)) Use this method if you are adding a container which uses the default property ids like BeanItemContainer for instance. If you are using custom properties instead use setContainerDataSource(Container.Indexed, Object, Object, Object, Object, Object) Please note that the container must be sorted by date!

```
    Description copied from interface: CalendarEventProvider
    
    Gets all available events in the target date range between startDate and endDate. The Vaadin Calendar queries the events from the range that is shown, which is not guaranteed to be the same as the date range that is set.
    
    For example, if you set the date range to be monday 22.2.2010 - wednesday 24.2.2010, the used Event Provider will be queried for events between monday 22.2.2010 00:00 and sunday 28.2.2010 23:59. Generally you can expect the date range to be expanded to whole days and whole weeks.
    
    Specified by:

  - addActionHandler
```
public void addActionHandler(Action.Handler actionHandler)
```
    Adds an action handler to the calender that handles event produced by the context menu.
    The Action.Handler.getActions(Object, Object) parameters depend on what view the Calendar is in:
    
    If the Calendar is in Day or Week View then the target parameter will be a CalendarDateRange with a range of half-an-hour. The Action.Handler.getActions(Object, Object) method will be called once per half-hour slot.
    
    If the Calendar is in Month View then the target parameter will be a CalendarDateRange with a range of one day. The Action.Handler.getActions(Object, Object) will be called once for each day.
    The Dates passed into the CalendarDateRange are in the same timezone as the calendar is.
    
    The Action.Handler.handleAction(Action, Object, Object) parameters depend on what the context menu is called upon:
    
    If the context menu is called upon an event then the target parameter is the event, i.e. instanceof CalendarEvent
    
    If the context menu is called upon an empty slot then the target is a Date representing that slot
