"The calendar control allows the user to pick a date interactively.

The CalendarCtrl displays a window containing several parts: the
control to pick the month and the year at the top (either or both of
them may be disabled) and a month area below them which shows all the
days in the month. The user can move the current selection using the
keyboard and select the date (generating EVT_CALENDAR event) by
pressing <Return> or double clicking it.

It has advanced possibilities for the customization of its
display. All global settings (such as colours and fonts used) can, of
course, be changed. But also, the display style for each day in the
month can be set independently using CalendarDateAttr class.

An item without custom attributes is drawn with the default colours
and font and without border, but setting custom attributes with
`SetAttr` allows to modify its appearance. Just create a custom
attribute object and set it for the day you want to be displayed
specially A day may be marked as being a holiday, (even if it is not
recognized as one by `wx.DateTime`) by using the SetHoliday method.

As the attributes are specified for each day, they may change when the
month is changed, so you will often want to update them in an
EVT_CALENDAR_MONTH event handler.", "

Window Styles

The default calendar style is CAL_SHOW_HOLIDAYS.

Events
-------
    =============================  ==============================
    EVT_CALENDAR                   A day was double clicked in the
                                   calendar.
    EVT_CALENDAR_SEL_CHANGED       The selected date changed.
    EVT_CALENDAR_DAY               The selected day changed.
    EVT_CALENDAR_MONTH             The selected month changed.
    EVT_CALENDAR_YEAR              The selected year changed.
    EVT_CALENDAR_WEEKDAY_CLICKED   User clicked on the week day
                                   header
    =============================  ==============================

Note that changing the selected date will result in one of
EVT_CALENDAR_DAY, MONTH or YEAR events and an EVT_CALENDAR_SEL_CHANGED
event.
