Features Explained:

1. Class-Based Design: This approach organizes the GUI in a class, making it more modular and scalable.
2. Navigation: The show_previous_year and show_next_year methods allow the user to navigate through different years without manually entering the year each time.
3. Input Validation: It handles invalid inputs by showing an error dialog box using messagebox.showerror.
4. Fixed-Width Font: The Text widget uses the "Courier" font, which is monospaced. This ensures that the calendar is displayed in a structured manner, maintaining the proper alignment of days.
5. Clear Button: Resets the calendar display and input fields.
6. Responsive Buttons: Users can navigate to previous and next years with dedicated buttons, and also exit the application with the Exit button.
7. Modern Styling: The GUI uses a clean and simple style with padding and proper layouts for a pleasant user experience.

How it Works:

• Year Input: Users enter a year in the input field or navigate between years using the “Previous Year” and “Next Year” buttons.
• Calendar Display: The calendar is displayed in a fixed-width Text widget, ensuring that the months and days are aligned correctly.
• Error Handling: If the user enters an invalid year (non-integer), an error message is shown.
