     - **Delete Task**: Lets you delete a task by specifying its number in the list.

     - **Quit**: Exits the application.

4. **Data Storage**:

   - The tasks are stored in a JSON file named `tasks.json` in the same directory as the script.

## Data Persistence

The application loads tasks from the `tasks.json` file when it starts and saves tasks back to the file after any additions or deletions. This ensures that your tasks are retained even when the application is closed and reopened.

## Error Handling

The application checks for invalid date formats and incorrect task numbers, providing appropriate error messages to guide the user.

## Important Notes

- Please ensure that you have Python installed on your system.
- Make sure to provide dates in the specified format (YYYY-MM-DD).
- Be cautious when deleting tasks, as this action is irreversible.
