Months and Days of the Week Are Proper Nouns
Similar to months (January, February), days of the week are specific names for particular times. Just as you would never write "january" or "february," you should never write "monday" or "tuesday." Capitalizing these terms helps readers distinguish them from common nouns or adjectives.
Capitalization in Titles and Headings
When writing titles or headings, days of the week remain capitalized. For example:
- Correct: "Meeting on Friday Afternoon"
- Incorrect: "Meeting on friday afternoon"

Some people mistakenly write days of the week in lowercase, especially in casual contexts like text messages or social media. Even so, even in informal writing, consistency matters. While grammar rules may seem strict, maintaining proper capitalization ensures professionalism and readability.

Days can sometimes function as adjectives, such as in the phrase "Monday’s weather" or "Friday night." Even in these cases, the day itself is still capitalized because it remains a proper noun. For example:
- Correct: "The Monday schedule has changed."
- Correct: "We’re meeting on Friday evening."
