Is autumn capitalized?

No, “autumn” is not usually capitalized, as it is a common noun. However, you must capitalize “autumn” when it’s the first word in a sentence or when it’s part of a proper noun (e.g., “the Mid-Autumn Festival”).

Some people may also capitalize “autumn” when it’s used in a felicitation, such as “Happy Autumn,” though this is technically incorrect unless the felicitation functions as a title or header.
