How to Spell Valentine’s Day: The Quick Answer
The simplest rule: the name is possessive and both words are capitalized. That means the correct spelling is Valentine’s Day, with an apostrophe before the s and a capital V and D.
Use the greeting “Happy Valentine’s Day!” on cards and messages. The apostrophe shows the possession—the day belongs to Saint Valentine—so the punctuation is not optional.
Avoid forms like valentines day, valentine day, or lowercase valentine’s day in formal writing. Those variants look informal and can be marked wrong in published pieces and brand materials.
- Use Valentine’s Day for the February holiday every time.
- Include the apostrophe; it shows possession and clarifies meaning.
- Capitalize both words because this is a proper name for a holiday.

Why the Apostrophe and Capitals Matter
Correct punctuation links the name to its origin. The possessive apostrophe shows the holiday belongs to its namesake. Think of Father’s Day or St. Patrick’s Day — each uses that mark to show ownership.
The possessive apostrophe: honoring Saint Valentine
The name traces back to Saint Valentine of Rome. That history explains why we write an apostrophe before the s: it marks the day as belonging to one saint. If you ever have a question about placement, remember the apostrophe goes before the s because the name is singular.
Capitalization rules: a proper noun holiday
As a proper noun, both parts are capitalized. Use capitals for clarity and formality. In contrast, the common word valentine (a card or sweetheart) stays lowercase. Avoid flattening the name into “Valentines Day” or “Valentine Day,” which drop the possessive and look incorrect.

When to Use “valentine” vs. “valentines” (and When to Capitalize)
A few quick checks will stop common mix-ups with valentine and valentines.
Lowercase valentine as a common noun: use it when you mean a card or a sweetheart. For example, write, “He asked me to be his valentine.” That keeps the word a simple noun and avoids extra punctuation.
Pluralize without an apostrophe: make more than one by adding an s. Say, “I passed out many valentines this year.” Do not add an apostrophe for plurals; that error confuses meaning.

- Treat valentine as a common noun for cards or people you adore.
- Use valentines for multiple cards or sweethearts—no apostrophe.
- Capitalize and keep the apostrophe when the proper noun holiday modifies a product: for example, Valentine’s Day cards.
- For generic product labels, lowercase works: valentine cards or valentine hearts.
When you’re unsure, ask whether you name the holiday or an ordinary item. Good punctuation and clear choices keep your writing polished. For related tips, see the Lovers tarot.
Common Spelling & Punctuation Mistakes to Avoid
Small slips in punctuation or caps can change meaning fast. Keep the holiday name formal and clear so your message stays focused on love, not errors.
Quick right vs. wrong: write “Happy Valentine’s Day!” not “Happy Valentines Day”, “Happy Valentine Day”, or the misheard “Happy Valentimes Day.”
Use lowercase valentine for a card or sweetheart in normal prose. Still, designers often pick Be my Valentine for visual impact; that is a stylistic choice, not a rule.

| Incorrect | Why it’s wrong | Correct |
|---|---|---|
| Valentines Day | Missing apostrophe; loses possession | Valentine’s Day |
| Valentine Day | Drops the possessive and looks informal | Valentine’s Day |
| Valentimes Day | Typo from mishearing the word | Valentine’s Day |
| valentines (plural) | Should not use an apostrophe for plurals | valentines (no apostrophe) |
- Don’t drop the apostrophe: the holiday is possessive.
- Plural cards or sweethearts are valentines, no apostrophe.
- Fix double errors like “happy valentines day” by capitalizing and adding the apostrophe.
- For event or product names, use the full formal name, for example a Valentine’s Day sale, or consult creative phrasing on related gift ideas.
Conclusion
Wrap up your note with the simple rule that makes every greeting look professional.
Use the correct spelling and punctuation: the holiday name needs capitals and an apostrophe because it honors saint valentine. For cards or a sweetheart, treat valentine as a common noun; for more than one, write valentines with no apostrophe.
