What does 'Day' return in date formats?

The correct answer indicates that the 'Day' format returns the name of the day with the first letter capitalized. This is particularly helpful in scenarios where you want to present date-related information in a more readable and user-friendly manner. For instance, using 'Monday', 'Tuesday', etc., allows the output to maintain a balance between formality and familiarity, making it suitable for various contexts such as reports or user interfaces.

Other options offer variations on capitalization styles, such as all capitalized or completely lowercase, which may be less visually appealing or harder to read. The format with just the initial capital letter aligns well with common writing conventions in English, which generally capitalize the first letter of proper nouns, including days of the week. This approach enhances clarity while keeping the information accurate and professional.
