Days, Months, and Holidays Capitalization — Grade 4
Grade 4 practice: identify, correct, and write sentences using the capitalization rule for days, months, and holidays while keeping seasons lowercase.
This worksheet helps Grade 4 students apply one of the most commonly tested capitalization rules: knowing which time-related words need a capital letter and which do not. Days of the week and months of the year are proper nouns, so they are always capitalized. Holiday names like Thanksgiving and Independence Day are also proper nouns and follow the same rule. Seasons, however, are common nouns — spring, summer, autumn, and winter stay lowercase. Students often mix these up because seasons feel as specific as months. The four sections move from finding errors to fixing them to writing original sentences, giving students repeated, varied practice with the rule. Print one copy per student and review the Section D answers together as a class.

Notes for the grown-up
- Students often capitalize seasons by analogy with months — watch for written errors like 'I love the Spring weather.'
- When a student capitalizes a season, ask: is this the name of a day, month, or holiday? If not, it stays lowercase.
- A student is ready to move on when they can explain, in their own words, why Summer is wrong but August is right.
