pyqt5 layout

You should use layout managers instead of manually positioning the widget. Qt for C++ is so cloe to Python Qt that all help for C++ is applicable to Qt5 or PySide2/6

            '12:00 AM',
            font=QtGui.QFont(font, 60))
        self.date = QtWidgets.QLabel(
            'Wednesday, December 31, 2020',
            font=QtGui.QFont(font, 30))
        layout = QtWidgets.QVBoxLayout(self)
        layout.addWidget(self.time)

        update.start(1000)
 
App = QtWidgets.QApplication(sys.argv)
window = Window() 
window.setStyleSheet(stylesheet)
window.show()
App.exit(App.exec_())
