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

4. **Data Storage**:

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

- Make sure to provide dates in the specified format (YYYY-MM-DD).
- Be cautious when deleting tasks, as this action is irreversible.
