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

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = MyApp()
    sys.exit(app.exec_())

One calendar and one label that displays the date appear in the widget window.

Description

cal = QCalendarWidget(self)
cal.setGridVisible(True)
cal.clicked[QDate].connect(self.showDate)

Create one object (cal) for QCalenderWidget.

If set ToGridVisible (True), a grid is displayed between dates.

Connects the showDate method to be called when the date is clicked.

self.lbl = QLabel(self)
date = cal.selectedDate()
self.lbl.setText(date.toString())

SelectedDate has the currently selected date information. (The default is the current date)

Displays the current date information on the label.

vbox = QVBoxLayout()
vbox.addWidget(cal)
vbox.addWidget(self.lbl)

Using a vertical box layout, you can place calendars and labels vertically.

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

In the showDate method, each time you click a date, the label text is displayed as the selected date (date.toString()).
