PyQt5 QCalendarWidget – Getting First Day of Week

In this article we will see how we can get the first day of the week of the QCalendarWidget. When we create a calendar by default first day of the week is Monday although we can change this any time, days are displayed in the first column of the calendar. We can change the first day any time with the help of setFirstDayOfWeek method.

In order to do this we will use firstDayOfWeek method with the QCalendarWidget object.

Syntax : calendar.firstDayOfWeek()
Argument : It takes no argument
Return : It return day object but when printed it shows the value associated with them 

Below is the implementation  

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 650, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for components
    def UiComponents(self):

        # creating a QCalendarWidget object
        self.calendar = QCalendarWidget(self)

        # setting geometry to the calendar
        self.calendar.setGeometry(50, 10, 400, 250)

        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)

        # setting first day of week
        self.calendar.setFirstDayOfWeek(Qt.Wednesday)

        # creating label to show the properties
        self.label = QLabel(self)

        # setting geometry to the label
        self.label.setGeometry(100, 280, 250, 60)

        # making label multi line
        self.label.setWordWrap(True)


        # getting first day of the week
        value = self.calendar.firstDayOfWeek()

        # setting text to the label
        self.label.setText("First Day of Week :" + str(value))




# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
