    import sys
    from PyQt4 import QtGui, QtCore
    
    class Example(QtGui.QWidget):
        
        def __init__(self):
            super(Example, self).__init__()
            
            self.initUI()
        
        
        def initUI(self):      
    
            cal = QtGui.QCalendarWidget(self)
            cal.setGridVisible(True)
            cal.move(20, 20)
            cal.clicked[QtCore.QDate].connect(self.showDate)
            
            self.lbl = QtGui.QLabel(self)
            date = cal.selectedDate()
            self.lbl.setText(date.toString())
            self.lbl.move(130, 260)
            
            self.setGeometry(300, 300, 350, 300)
            self.setWindowTitle('Calendar')
            self.show()
            
        def showDate(self, date):     
        
            self.lbl.setText(date.toString())
        
        
    def main():
        
        app = QtGui.QApplication(sys.argv)
        ex = Example()
        sys.exit(app.exec_())
    
    
    if __name__ == '__main__':
        main()
    

    The example has a calendar widget and a label widget. The currently selected date is displayed in the label widget.

    cal = QtGui.QCalendarWidget(self)
    

    We construct a calendar widget.

    cal.clicked[QtCore.QDate].connect(self.showDate)
    

    If we select a date from the widget, a clicked[QtCore.QDate] signal is emitted. We connect this signal to the user defined showDate() method.

    def showDate(self, date):     
        self.lbl.setText(date.toString())
    

    We retrieve the selected date by calling the selectedDate() method. Then we transform the date object into string and set it to the label widget.
