Developing a React calendar application involves creating a dynamic, interactive interface that allows users to view, add, edit, and manage events on a calendar. Here’s a brief summary of the key steps involved:

1. Setup Environment: Set up your React development environment using tools like create-react-app, Vite, or Next.js. Install necessary dependencies such as dayjs or date-fns for date manipulation, and optionally, a state management library like Redux Toolkit.

2. Design the UI: Create the basic layout of the calendar, including a header (for month/year navigation) and a grid to display days of the month. You can use libraries like React Bootstrap, Material-UI, or Tailwind CSS for styling.

3. Build Calendar Logic:

• Calculate days of the month, weeks, and display them correctly in the calendar grid.
• Highlight the current date, weekends, and any special days.
• Allow navigation between months and years using buttons or dropdowns.

4. Event Management:

• Allow users to add, edit, and delete events on specific dates.
• Use modals or side panels for user interactions when creating or editing events.

5. State Management:

• Use state management to keep track of the current date, selected date, and events.
• Store events locally or connect to a backend API/database for persistent storage.

6. Deployment:

• Deploy the application using platforms like Netlify, Vercel, or GitHub Pages.
