Bug: getSelectedDay() with default value returns wrong month

[tomdaniel-it]

When nothing has been selected yet, the method getSelectedDay() (in CollapsibleCalendar) will return a Day object created with the day, month & year from Calendar, but with month, a +1 is added. This is inconsistent since the normal value when something is selected does not do a +1.
Calendar.get(2) returns the month starting from 0 - 11. With the +1, it changes to 1-12.
So: when nothing in calendar has been clicked yet, day.getMonth() returns 4. When I then click on the day of today, that day gets selected. Then day.getMonth() prints out 3. (day == getSelectedDay())
Recommendation:
In CollapsibleCalendar in getSelectedDay() change:
return new Day(year, month + 1, day);
to:
return new Day(year, month, day);
