The first thing is to obtain the QSpinBox that shows the year using findChildren, then it is to detect the mouse event but as this solution points out it is not possible so a workaround is to detect the focus event:

from PyQt5 import QtCore, QtWidgets


class MainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)

        self.calendar_widget = QtWidgets.QCalendarWidget()
        self.setCentralWidget(self.calendar_widget)

        self.year_spinbox = self.calendar_widget.findChild(
            QtWidgets.QSpinBox, "qt_calendar_yearedit"
        )

        self.year_spinbox.installEventFilter(self)

    def eventFilter(self, obj, event):
        if obj is self.year_spinbox and event.type() == QtCore.QEvent.FocusIn:
            print(self.year_spinbox.value())

        return super().eventFilter(obj, event)


if __name__ == "__main__":
    import sys

    app = QtWidgets.QApplication(sys.argv)
    w = MainWindow()
    w.show()
    sys.exit(app.exec_())
