Definition: Days of the Week Capitalization
In English grammar, days of the week are considered proper nouns and, therefore, are always capitalized. A proper noun is a specific name for a person, place, or thing. Days of the week (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday) are specific names, distinguishing them from common nouns like “day” or “week,” which are not capitalized unless they begin a sentence.
The function of capitalizing days of the week is to identify them as unique entities within a calendar system. This convention aids in clarity and avoids confusion, particularly in schedules, calendars, and written communication where specific days are being referenced.
Not capitalizing them would be considered a grammatical error in most formal writing contexts.
The capitalization rule applies consistently across various contexts, including:
- Formal writing: essays, reports, business correspondence
- Informal writing: emails, personal letters, social media posts
- Calendar entries and schedules
- Newspaper articles and publications
Structural Breakdown
The structure of days of the week is straightforward. Each day is a single word, and the first letter of each word is capitalized.
Although the individual days have etymological roots in various cultures and mythologies (e.g., Monday from “Moon’s day”), their grammatical structure in modern English is uniform.
The capitalization rule applies regardless of where the day of the week appears in a sentence. Whether it is at the beginning, middle, or end of a sentence, the day of the week must be capitalized.
Furthermore, abbreviations and shortened forms of days of the week also retain capitalization (e.g., Mon., Tue., Wed.).
Here’s a breakdown of the correct capitalization for each day of the week:
- Monday
- Tuesday
- Wednesday
- Thursday
- Friday
- Saturday
- Sunday

Usage Rules for Capitalizing Days of the Week
The primary rule is simple: always capitalize the days of the week. This rule applies universally in written English. However, understanding the nuances and exceptions can further refine your grasp of the concept.
- Consistency: Maintain consistent capitalization throughout your writing. If you capitalize days of the week in one section, do so in all sections.
- Abbreviations: When using abbreviations, ensure the first letter is capitalized (e.g., Mon., Tue., Wed.).
- Sentence Start: If a day of the week begins a sentence, it must still be capitalized (e.g., “Monday is the first day of the week.”).
Exceptions:
There are very few true exceptions to this rule. In extremely informal contexts, such as casual text messages or handwritten notes to oneself, the capitalization rule might be relaxed.
However, in any formal or professional writing, capitalizing days of the week is essential.
In some programming languages or data formats, days of the week might be represented in lowercase for specific technical reasons. However, this is not an exception to the grammatical rule in English writing.

- Incorrect Abbreviation Capitalization: Some writers may incorrectly capitalize or punctuate abbreviations of days of the week (e.g., “mon” instead of “Mon.”).

Advanced Topics: Days of the Week in Different Contexts
Beyond the basic capitalization rule, there are more nuanced aspects to consider when using days of the week in different contexts.
- Formal vs. Informal Writing: While capitalization is generally required, extremely informal writing (e.g., personal notes) might occasionally omit it. However, this is not recommended for any professional or academic context.
- Cultural Differences: Although the English capitalization rule is consistent, other languages may have different conventions. Be mindful of these differences when writing in or translating from other languages.
- Software and Programming: In programming, days of the week are often represented numerically or with specific codes that may not follow standard capitalization rules. These are technical exceptions and do not affect the grammatical rule in English writing.
Understanding these advanced topics can help you navigate complex writing scenarios and ensure your usage of days of the week is always accurate and appropriate.
