Common Mistakes to Watch Out For
Even seasoned writers occasionally slip up when it comes to day‑of‑the‑week capitalization. Below are some of the most frequent errors and tips for avoiding them.
| Mistake | Why It’s Wrong | How to Fix It |
|---|---|---|
| lowercasing the first letter – “we will meet on monday” | Days are proper nouns, not common nouns. | Capitalize the M: “Monday.In practice, ” |
| mixing case in a series – “Monday, tuesday, WEDNESDAY” | Inconsistent styling looks unprofessional and can confuse readers. On the flip side, | Keep the same capitalization for each entry: “Monday, Tuesday, Wednesday. That's why ” |
| using all caps – “MONDAY” | All‑caps can be interpreted as shouting and removes the subtle visual cue that the word is a proper noun. | Use standard title case unless the entire document follows an all‑caps format for headings. |
| incorrect abbreviation – “Mo.” or “Tues” | The accepted abbreviations are “Mon.Here's the thing — ” and “Tue. ” (or “Tues.That said, ” in some style guides). | Refer to your organization’s style guide; most recommend “Mon.” and “Tue.” |
| treating “day” as a generic label – “the day after Friday” | Even when “day” is used generically, the specific day name still needs a capital. | Write “the day after Friday. |
Style Guides and Their Nuances
While the rule “always capitalize days of the week” is universal, different style manuals provide additional guidance on formatting:
- APA (American Psychological Association): Capitalize days when they appear in the text, but use lowercase when the day is part of a date expression that includes a month and year (e.g., “April 5, 2024, was a Friday”).
- Chicago Manual of Style: Recommends capitalizing days in all contexts, including headings and tables, unless a specific design choice dictates otherwise.
- AP (Associated Press): Capitalizes days in narrative text but prefers lowercase when the day appears in a headline that follows “sentence case” rules.
- MLA (Modern Language Association): Mirrors Chicago’s approach—full capitalization across prose and works‑cited entries.
When writing for a particular publication or organization, always defer to its chosen guide. If no guide is specified, the default rule—capitalize every day—remains safe Simple, but easy to overlook..
Capitalization in Multilingual Contexts
If your text includes foreign language terms for days (e.g., “lunes” in Spanish or “lundi” in French), the capitalization rules follow the conventions of those languages:
- Spanish: Days are not capitalized unless they start a sentence.
- French: Same as Spanish—lowercase unless at the beginning of a sentence.
- German: Days are always capitalized because all nouns are capitalized in German.
When mixing English with another language in the same document, keep each language’s rules separate to avoid awkward hybridization. For example:
“Our meeting is scheduled for Wednesday, miércoles, and Mittwoch.”
Digital Tools to Enforce Proper Capitalization
Modern writing software can help you stay consistent:
- Grammar checkers (Grammarly, ProWritingAid) flag lowercase days as errors.
- Word processors (Microsoft Word, Google Docs) allow you to create custom autocorrect entries—type “monday” and have it automatically corrected to “Monday.”
- Style‑guide plugins for LaTeX or Markdown can enforce capitalization across large documents, useful for academic theses or technical manuals.
