📝 Description

We need a simple interactive calendar that displays the days of a selected month and year.
The goal is to help beginners practice date manipulation, DOM updates, and dynamic UI rendering in JavaScript.

🎯 Requirements

  • Display all days of the chosen month and year
  • Highlight the current date
  • Allow users to navigate between months and years
  • Implement a responsive design for different screen sizes

💡 Concepts to Demonstrate

  • Date and time manipulation using the JavaScript Date object
  • DOM manipulation to dynamically render the calendar grid
  • Event handling for navigation buttons (next/previous month, year)
  • Efficient dynamic rendering of calendar days

🚀 Bonus Challenge

  • Add the ability to mark important dates or events
  • Display a small event tooltip or modal when clicking on a date

📦 Deliverables

  • A working example using HTML, CSS, and JavaScript
  • Include a short README or inline comments explaining how the calendar works
  • Submit your solution as:
    • A pull request in the examples/ folder, or
    • A CodePen, JSFiddle, or GitHub Gist link
