Which capitalization is correct for a date?

• A. She visited the hospital on Monday, March 3, 2024.
• B. She visited the hospital on monday, March 3, 2024.
• C. She visited the hospital on Monday March 3, 2024.
• D. She visited the hospital on Monday, March 3 2024.

Answer: (A)

Capitalization and punctuation in dates matter for clear writing. Days of the week and months are always capitalized, and when a date appears with a day of the week, you include a comma after the day of the week and a comma between the day and the year. This makes the date read smoothly and unambiguously. The form that follows this pattern is the correct one: She visited the hospital on Monday, March 3, 2024. It uses Monday with a capital M, March with a capital M, and the two commas: after the day of the week and between the day and the year. The other versions break rules in small but important ways. Using monday with a lowercase m violates capitalization rules. Omitting the comma after Monday makes the date flow incorrectly into the month. Leaving out the comma between the day and the year also disrupts standard date formatting, as seen in the version that ends with 3 2024.
