Capitalization is the use of uppercase (capital) letters at the beginning of certain words. We capitalize names, places, days of the week, months of the year, and holidays.
Capital letters show importance and help readers recognize special words quickly.
Every day of the week begins with a capital letter. Even though we use these words often, they are still proper nouns and need to be capitalized.
Days are always capitalized, whether they appear at the beginning, middle, or end of a sentence.
Each month of the year also begins with a capital letter. Months are proper nouns just like days of the week.
Do not confuse seasons (spring, summer, fall, winter) with months. Seasons are not capitalized unless they are part of a proper name (for example, Spring Festival).
Holidays are special days, and they always begin with capital letters. Each word in the holiday’s name is usually capitalized.
When writing holidays, be sure to check whether each word in the holiday’s name should be capitalized.
When you write days, months, or holidays in sentences, they must always be capitalized, just like names of people or places.
Always proofread your writing to check that days, months, and holidays are capitalized correctly.
