Ever stopped mid-sentence while typing a weekly plan? You looked at the screen and wondered about Thursdays or Thursday’s. You’re not alone. That tiny apostrophe trips up students, bloggers, and busy professionals every week. One small mark can change the whole meaning of a sentence.
Here’s the good news. The rule is simple once you see it. This guide breaks down when to use Thursdays or Thursday’s with plain words and real examples. You’ll also find tables, quick tests, and memory tricks. Soon you’ll pick the right form without a second thought.
Quick Answer: Thursdays or Thursday’s?
Use “Thursdays” for more than one Thursday. Use “Thursday’s” to show ownership or to shorten “Thursday is” or “Thursday has.”
Here’s the fast version for Thursdays or Thursday’s:
- “I swim on Thursdays.” (every Thursday)
- “Thursday’s game was fun.” (the game belongs to Thursday)
- “Thursday’s the day we leave.” (Thursday is)
No apostrophe means plural. An apostrophe means possession or a contraction. That’s the whole secret.
What Does Thursdays Mean?
“Thursdays” means every Thursday, or more than one Thursday. It’s the plural form of the noun Thursday.
Writers often use it to show a habit or a schedule. For example, “The library closes early on Thursdays.” Here, the library does this every week.
You can also use it as an adverb. “I work Thursdays” means you work every Thursday. Both ways are correct. Notice that there’s no apostrophe in any of these. The word isn’t owning anything. It simply counts more than one day.
What Does Thursday’s Mean?
“Thursday’s” shows that something belongs to Thursday or comes from Thursday. It can also be a short form of “Thursday is.”
Look at these examples:
- Thursday’s weather looks cloudy. (possession)
- Thursday’s lesson was about verbs. (possession)
- Thursday’s my favorite day. (Thursday is)
The apostrophe does the work here. It either links the day to a thing, or it replaces missing letters. Context tells you which job it’s doing.
Thursday’s as a Contraction
A contraction joins two words and drops some letters. The apostrophe marks the missing spot. So “Thursday is” becomes “Thursday’s.”
It also works for “Thursday has.” For example, “Thursday’s been a long day.” That means “Thursday has been a long day.”
Contractions sound friendly and casual. They fit emails to friends, texts, and blog posts. However, they can feel too relaxed in a legal paper or a formal report. In those places, spell out “Thursday is.”
The History of Thursday
Thursday gets its name from Thor, the Norse god of thunder. In Old English, it was reportedly “Thunresdæg,” meaning “Thunor’s day.”
The Romans named the same day after Jupiter, their sky god. Their Latin name was “dies Iovis.” Many Romance languages kept that link. In French, Thursday is “jeudi,” which echoes Jupiter.
So the day has carried a thunder theme for centuries. The English plural, “Thursdays,” simply adds an s to that old name. The apostrophe form came later, as English settled its possessive rules.
Thursdays or Thursday’s Meaning
The meaning of Thursdays or Thursday’s depends on the job the word does in your sentence. One counts days. The other shows a link or a short form.
Think of it like this:
| Form | Job | Example |
| Thursdays | Plural | We meet on Thursdays. |
| Thursday’s | Possessive | Thursday’s agenda is short. |
| Thursday’s | Contraction | Thursday’s almost here. |
Once you know the job, the spelling follows. Ask yourself one question. Am I counting days, or showing ownership? That answer picks your form.
British English vs. American English
Both versions of English follow the same apostrophe rules. The differences are small and mostly about style, not grammar.
Spelling can differ between the two, though. A good example is focusses or focuses, where British and American habits split. Weekday plurals aren’t like that. They behave the same on both sides of the Atlantic.
British English
British writers often add “on” before the plural. They say, “I play football on Thursdays.” They also tend to write dates as “Thursday 5 March.”
In the UK, the plural and possessive rules match American ones. A British writer still writes “Thursday’s meeting” for a meeting that belongs to Thursday. Many British style guides also prefer fewer commas in dates.
American English
American writers often drop “on” in casual speech. They say, “I work Thursdays.” That’s perfectly fine.
Dates usually follow the pattern “Thursday, March 5.” The comma after the weekday is common. The apostrophe rules stay exactly the same. “Thursday’s game” is possessive in both countries.
The Main Point
The main point about Thursdays or Thursday’s is simple. Region doesn’t change the apostrophe rule. It changes only small habits, like “on” and date order.
So don’t worry about which country your reader lives in. Learn the three jobs once. Then use them anywhere in the English-speaking world.
When Should You Use Thursdays?
Use “Thursdays” when you mean a repeated event or more than one Thursday. No apostrophe is needed.
Try these examples:
- “She teaches yoga on Thursdays.”
- “Most Thursdays feel quiet at the office.”
- “The cafe is closed Thursdays.”
- “All four Thursdays in November were rainy.”
Notice the pattern. Each sentence talks about habit, schedule, or count. Nothing in them owns anything. If you can swap the word for “every Thursday,” you’re on the right track.
When Should You Use Thursday’s?
Use “Thursday’s” when something belongs to a single Thursday. Also use it when you’re shortening “Thursday is” or “Thursday has.”
Here are some clear cases:
- “Thursday’s forecast calls for snow.” (possession)
- “I missed Thursday’s class.” (possession)
- “Thursday’s here already!” (Thursday is)
- “Thursday’s been busy.” (Thursday has)
A quick test helps. Replace the word with “the … of Thursday.” If “the forecast of Thursday” works, use the apostrophe. If “Thursday is” fits, you have a contraction.
Every Thursday or Every Thursdays?
“Every Thursday” is correct. “Every Thursdays” is wrong. The word “every” needs a singular noun after it.
Think about it. You’d say “every day,” not “every days.” You’d say “every week,” not “every weeks.” Thursday works the same way.
Still, you can write “on Thursdays” with the plural. Both patterns share one meaning. They just use different grammar paths to get there.
Every Thursday
“Every Thursday” uses a singular noun. It points to each Thursday one at a time.
Examples:
- “We bake bread every Thursday.”
- “Every Thursday, Maya calls her grandmother.”
This pattern feels clear and a bit more emphatic. It’s a safe choice for formal writing too.
On Thursdays
“On Thursdays” uses the plural. It treats all Thursdays as one group.
Examples:
- “On Thursdays, we eat pizza.”
- “He volunteers on Thursdays.”
It sounds smooth in speech. Both versions are correct. Pick the one that fits your rhythm.
The Four Main Forms of Thursday
Thursday appears in four spellings, but five jobs. That’s because “Thursday’s” does double duty. It can be a possessive or a contraction.
Learn these forms, and every sentence gets easier. The word also follows the same pattern as the other six days of the week. Plurals just add an s. Possessives add an apostrophe.
Here’s a handy table:
| Form | Type | Example |
| Thursday | Singular | I’ll see you Thursday. |
| Thursdays | Plural | Thursdays are busy. |
| Thursday’s | Singular possessive | Thursday’s speech was short. |
| Thursday’s | Contraction | Thursday’s my day off. |
| Thursdays’ | Plural possessive | Thursdays’ traffic is heavy. |
Thursday — Singular
“Thursday” names one day. It’s a proper noun, so it always starts with a capital letter.
Examples:
- “The test is on Thursday.”
- “Thursday was sunny.”
It works as a noun and, in casual speech, as an adverb. “See you Thursday” is common and correct.
Thursdays — Plural
“Thursdays” names more than one Thursday. You form it by adding s. Words ending in a vowel plus y just take an s. There’s no spelling change at all.
Plurals can still surprise people, as in skis or skiis. With Thursday, the plural is easy. Add s and stop.
Example: “Thursdays are for pasta night.”
Thursday’s — Singular Possessive
This form shows that one thing belongs to one Thursday. The rule is to add an apostrophe and an s.
Examples:
- “Thursday’s homework was easy.”
- “We loved Thursday’s concert.”
The owner is a single day. So the apostrophe sits before the s.
Thursday’s — Contraction
Here the apostrophe stands in for missing letters. It replaces the “i” in “is” or the “ha” in “has.”
Examples:
- “Thursday’s my lucky day.”
- “Thursday’s come and gone.”
It looks the same as the possessive. Only the meaning separates them. Read the sentence out loud with “is” or “has” to check.
Thursdays’ — Plural Possessive
This form shows ownership by more than one Thursday. The apostrophe goes after the s.
Examples:
- “The Thursdays’ events were all free.”
- “Those Thursdays’ meetings ran long.”
It’s rare in daily writing. Most people rewrite the sentence to avoid it. For example, “the meetings on Thursdays” sounds smoother.
Thursday Pronunciation
Thursday is pronounced “THURZ-day” or “THURZ-dee.” Thursdays and Thursday’s sound exactly the same when spoken.
The first sound is the soft “th,” as in “thin.” The vowel is like the “ur” in “burn.” The ending can be “day” or “dee.” Many people use “dee” in fast speech. Both are fine.
Because all forms sound alike, speech gives no clue about the apostrophe. That’s why spelling errors are so common in writing. You can’t rely on your ear here.
Thursday’s Meeting: A Simple Example
“Thursday’s meeting” means the meeting that happens on Thursday. The apostrophe shows that the meeting belongs to that day.
Let’s compare three versions:
- “Thursday’s meeting starts at nine.” (possessive, one meeting)
- “Thursdays meetings start at nine.” (incorrect, missing apostrophe)
- “Our Thursday meetings start at nine.” (correct, Thursday works as a describing word)
The second one is a common slip. Also, notice the third option. English often lets a noun describe another noun. So “Thursday meetings” is correct without any apostrophe at all.
Thursdays or Thursday’s in Everyday Writing
The choice in Thursdays or Thursday’s changes slightly with the place you’re writing. A casual text allows more freedom than a legal paper. Still, the core rule stays fixed in every setting.
Let’s walk through the common spots.
Emails
In emails, clarity wins. Write “Our team call is on Thursdays” for a weekly habit. Write “Thursday’s agenda is attached” for one specific meeting.
Here is a practical tip for Thursdays or Thursday’s in work emails. Look at your subject line. A line like “Thursday’s Update” reads as one update. “Thursdays Update” looks like a typo. Fix it before you hit send.

News and Reports
News writers value short and exact language. They often write “on Thursday” for a single past event. For example, “The council voted on Thursday.”
For repeated events, they write “on Thursdays.” Possessives show up in lines like “Thursday’s storm caused delays.” Style guides, such as AP, also favor clear dates over vague weekdays when the timing matters.
Social Media and Casual Writing
Casual posts allow short forms and playful tone. “Thursday’s the new Friday” is a popular style of caption.
Even so, avoid the common slip. Don’t write “Thursday’s are for tacos.” That apostrophe is wrong, because the plural needs none. Write “Thursdays are for tacos.” Your followers will notice, and grammar fans love to comment.
Formal Writing
Formal writing calls for care. Skip most contractions. Write “Thursday is the deadline” instead of “Thursday’s the deadline.”
When you need Thursdays or Thursday’s in a report, test each one. Use “Thursdays” for repeated events. Use “Thursday’s” only for true possession, such as “Thursday’s findings.” Also consider giving the full date. “Thursday, March 5” removes any doubt.
Thursday Boots and Thursday’s Child
Thursday shows up in names and sayings, too. Two famous examples are a footwear brand and an old rhyme. Each one handles the apostrophe differently.
Thursday Boots
“Thursday Boots” is a footwear brand, reportedly founded in 2014 in the United States. Here, “Thursday” is part of a company name.
Brand names usually have no apostrophe. The name works like a label, not a possession. So you write “Thursday Boots” and not “Thursday’s Boots.” Always match the spelling a brand uses on its own website.
Thursday’s Child
“Thursday’s child” comes from an old nursery rhyme about children born on each day of the week. The line says Thursday’s child has far to go.
Here the apostrophe is correct. It’s possessive, since the child belongs to Thursday. The rhyme is believed to date back to the 1800s. It’s a lovely example of how apostrophes show ties between a day and a person.
Common Mistakes With Thursdays and Thursday’s
Most errors come from one habit. People add apostrophes where they don’t belong. Let’s look at the five slips that happen most.
Don’t feel bad if you’ve made them. Even skilled writers do. A short checklist at the end of each draft catches nearly all of them.
Mistake 1: Using an Apostrophe to Make Thursdays Plural
Wrong: “I love Thursday’s.”
Right: “I love Thursdays.”
Plurals never need an apostrophe. This is sometimes called the “greengrocer’s apostrophe,” like “banana’s for sale.” Skip it.
Mistake 2: Writing Every Thursdays
Wrong: “We meet every Thursdays.”
Right: “We meet every Thursday.”
“Every” takes a singular noun. If you want the plural, drop “every” and say “on Thursdays.”
Mistake 3: Confusing Plural and Possessive Forms
Wrong: “Thursdays plan is ready.”
Right: “Thursday’s plan is ready.”
If the plan belongs to Thursday, you need the apostrophe. A missing mark makes the word look plural. Readers then stumble.
Mistake 4: Missing a Contraction
Wrong: “Thursdays here already.”
Right: “Thursday’s here already.”
You meant “Thursday is.” The apostrophe must show the missing letters. Without it, the sentence feels broken.
Mistake 5: Confusing Thursday’s and Thursdays’
Wrong: “Thursdays’ forecast is sunny.” (for one day)
Right: “Thursday’s forecast is sunny.”
Put the apostrophe before the s for one day. Put it after the s for many days. Count the days first.
Which is Correct, Thursday or Thursday?
Both “Thursday” and “Thursdays” can be correct. Which one you use depends on whether you mean one day or many.
Use “Thursday” for a single day, as in “See you Thursday.” Use “Thursdays” for a repeated habit, as in “I run on Thursdays.” Meaning decides the answer. Neither form is wrong by itself.
Thursdays vs. Thursday’s: Comparison
The table below puts the key differences side by side. Bookmark it for quick checks.
| Feature | Thursdays | Thursday’s |
| Type | Plural noun | Possessive or contraction |
| Meaning | More than one Thursday | Belongs to Thursday, or “Thursday is” |
| Apostrophe | No | Yes |
| Example | I rest on Thursdays. | Thursday’s class is full. |
| Swap test | “every Thursday” | “of Thursday” or “Thursday is” |
A few extra points help:
- Plural words never take an apostrophe for counting.
- Possessives always need one.
- Contractions need one to mark the missing letters.
What About Google Trends and Search Usage?
Many people wonder which spelling folks search for most. Search tools can offer clues. Still, they don’t decide grammar.
Spelling rules come from style guides and dictionaries. Popularity doesn’t make a form right. Let’s see what the data can and can’t tell you.
What Usage Data Can Show
Search data can show how often people look up a phrase. It can reveal when interest rises, such as at the start of a school term. It can also show which wording confuses people most.
For writers, that’s useful. It points to topics readers care about. Related searches, like “Thursdays meaning” or “apostrophe in days of the week,” show what readers want explained.
What Google Trends Cannot Prove
Trends can’t prove a spelling is correct. A common mistake can be searched often. That doesn’t turn it into good grammar.
It also shows relative interest, not exact counts. So treat the data as a hint. For the final call, trust grammar guides and trusted dictionaries.
An Easy Way to Remember the Difference
Memory tricks make rules stick. For Thursdays or Thursday’s, you need only three short tests. Use them whenever you feel stuck.
Picture them as three quick questions. Ask them in order. By the third one, your answer is nearly always clear.
No Apostrophe = Plural
If you mean more than one Thursday, skip the apostrophe. Think “Thursdays are fun.”
Say it out loud with “all.” Would “all Thursdays” fit? Then it’s plural. You’re done.
Apostrophe + S = Possession or Contraction
If something belongs to Thursday, add the apostrophe and s. If you can say “Thursday is” or “Thursday has,” do the same.
Try this: “Thursday’s lunch is free.” Does “the lunch of Thursday” work? Yes. So the apostrophe stays.
Every + Singular
Whenever you see “every,” use the singular. Write “every Thursday.” Never write “every Thursdays.”
This one rule fixes a lot of errors. Pair it with “every day,” “every week,” and “every month.” They all work the same way.
Frequently Asked Questions

Use it for a repeated event or more than one Thursday, like “I swim on Thursdays.”

“Thursday’s” shows ownership by one day, while “Thursdays'” shows ownership by multiple days.
Conclusion
Now you know how to handle Thursdays or Thursday’s with confidence. “Thursdays” means more than one Thursday. “Thursday’s” shows possession or stands for “Thursday is” or “Thursday has.” “Thursdays’” covers rare plural ownership.
Remember the three quick tests. No apostrophe means plural. Apostrophe plus s means ownership or a contraction. After “every,” always choose the singular. Keep these in mind, and you’ll write sharper emails, posts, and reports. Go ahead and use them on your next draft.
