PyQt5 QCalendarWidget – Setting Timer Event
In this article we will see how we can implement the timer event for the QCalendarWidget. A timer event is sent to the calendar when the calendars startTimer interval is over. This event handler can be reimplemented in a subclass to receive calendar startTimer events which are passed in the event parameter.
Below is the Calendar class code

# QCalendarWidget Class
class Calendar(QCalendarWidget):
# constructor
def __init__(self, parent=None):
super(Calendar, self).__init__(parent)
# overriding the timer event
# this will show the next month
def timerEvent(self, event):
# show the next month
window.calendar.showNextMonth()
Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the timerEvent and inside the event show the next month of calendar
3. Create a main window class
4. Create a Calendar object inside the main window
5. Set various properties to the calendar
Below is the implementation
